Flipping the headset over, everyone immediately noticed the difference.

The first thing that catches the eye is naturally the two extra trapezoidal additional screens on the outside of the eyepiece, the big of which is next to the eyepiece, and the small head is bent into the frame, giving the impression that there is a screen outside the lens.

"I'm finally willing to spend money," this is Yuan Yang's opinion.

"Oh, it's really simple and rude!" Wang Shan commented.

Zhou Lin's gaze swept back and forth on the faces of the two, and he wanted to ask: What are you talking about?

Noticing the ignorant expression on his face, Yuan Yang first opened his mouth to explain, and pointed to the screen and said, "See, the trapezoidal curved screen, this must be specially customized by bees, and the cost must not be small." ”

"Can the screen still form a trapezoid?"

"Of course, you can just cut it in whatever shape you want. However, the panels that come down from the production line are rectangular, so they are usually cut into rectangular shapes. ”

"I don't think it's useful, it's almost up to the ear. ”

"If you don't put the screen behind your eyes, how do you think the 0-degree limit horizontal viewing angle came from?" interjected.

"Isn't the human eye 180, and is it useful to have an extra 50 degrees?" asked Zhou Linhaobao.

Wang Shan said: "The normal situation is 188, but the theoretical limit is 0, and no matter how many eyeballs there are, they will bulge." ”

"The biggest selling point of this machine is the large field of view, the picture fills the field of view, and the immersion must be great," Yuan Yang said with a smile.

"Let's try it when I find something," Zhou Lin said: "The custom screens are all out, if the effect is not good, won't it be blind?"

"Well, I'll pair them first," Yuan said.

His high-spec P has a whole bunch of test videos and games on it, which you can experience immediately with just a wireless connection. That being said, it was still a little troublesome to connect for the first time, because Yuan Yang didn't bring the handle over.

There was nothing to do, Wang Shan reached out and pulled the empty packaging box, turned it over to check the specifications on the back, and then he smiled.

"Brother Wang, what's the coke?" Zhou Lin quipped.

"Look at this!" the former fingers to the bottom of the box, where the words "Bee Mirage Design, Bee Optics Industrial Manufacturing" are printed in bold bold letters.

Zhou Lin was confused, and didn't find anything wrong with this, there were similar words on the boxes of mobile game consoles.

"I laugh at the fact that these glasses are made by the glasses factory, and the bees are too good. ”

Seeing that the other party hadn't laughed yet, Lao Wang had to explain patiently: "The optical industry is also a bee subsidiary, which specializes in the production of mobile phone lenses, and its positioning is somewhat similar to that of bee core semiconductors, of course, the latter does not have a wafer factory, while the former has a lens department and an assembly department." And then you get the idea? They make the whole machine, just like the bee core makes the mobile phone, it's very out of tune. ”

"I think it's normal," Yuan Yang said. He has already completed the setting, but he didn't put it on his head for the first time, but instead launched a running score software, and the test screen is beautifully made, which is more beautiful than most R games, but Yuan Yang has watched it hundreds of times, and he has long been aesthetically fatigued.

Putting the headset aside, he said: "Mirage itself does not have a factory, and the production is all OEM by other subsidiaries, and it used to be the No. 0 factory in Ludao. However, since the technical transformation of Factory 0 into a full robot factory last year, the high-end products such as N7 and BG3 have been replaced by Bee Optics, and visual inspection may be related to the accuracy of robot assembly. ”

"Isn't the accuracy of the robot higher than that of a human, and it can't make mistakes?"

Throwing a Yung look of contempt to his young colleague, Yuan Yang pricked up his hands and said: "Robots are better than good repeatability, as long as the equipment is not faulty, they can be repeated tens of thousands of times without making mistakes, but this does not mean that their accuracy can be higher than that of human hands." At least the work of a professional technician can throw them a few streets away. ”

"Snort!" Wang Shan suddenly laughed, he was poked by the statement that the technician had a good job.

"What's so funny?"

Of course, Lao Wang couldn't say that he thought of 280, but fortunately, he was in a hurry, and the head goggle next to his finger said: "The bee finally uses Fresnel, this should be the bee optics grinding itself, right?"

"Well, I just took a look at it, and the two shots work very well. ”

After being reminded by the two of them, Zhou Lin also looked at the two eyepieces of light and shadow, and found that its surface was not smooth and flat, and the circle of circular threads looked quite obvious, so he couldn't help asking: "Is the Fresnel lens like this?"

"Uh-huh, that's it. ”

In 1822, the French physicist Augin Fresnel designed this lens for the lighthouse as an alternative to the conventional convex lens. It replaces the large continuous curved surface of the latter with several small facets, which greatly reduces the thickness of the lens and the material requirement (optical glass is expensive). Its cross-section is serrated with serrated teeth, and the front view is a ring sleeve ring, so it is also called a threaded lens.

The more threads, the smaller the thickness and the more material saving, but the corresponding accuracy is also worse, so this lens is usually used in applications where thickness is emphasized and precision is not too important, such as searchlights and Fresnel lamps for photography. The core of the well-known Fresnel optical landing system is a signal lamp equipped with Fresnel lenses, which makes the signal beam as straight as possible and more indicative.

With the rapid development of semiconductor process technology, the ancient mirror-making industry has also been subverted, not by the improvement of computer mirror grinding machines, but by wafer lenses based on the theory of diffractive optics. That is, the production process of integrated circuits is used to produce lenses with photolithography, embossing and other technologies.

Because continuous surface processing is a problem in the world, continuous steps are commonly used to fit curved surfaces when producing lenses by semiconductor process, so diffractive optical elements (iffraiepialEleens, E) are also called binary optical components. This is a new type of device that does not look at the technology and the algorithm, and it is basically not compatible with the traditional mirror-making process.

Many modern Fresnel lenses are E because they can be used to maximize machining accuracy while ensuring mass production, and can even be used in laser beam shaping and eyeglasses where precision is required. For example, Mrs. Ke, the recently popular presidential candidate of the Donkey Party, has this left spectacle lens, which is used to correct strabismus and can achieve better results than traditional prisms.

And what makes ordinary people pay attention to them is because of H and ul, two R headset manufacturers. Both the former IE and the latter RIF use Fresnel lenses as eyepieces, but IE is standard, while the Rif has two different sets of lenses for users to replace.

For the R headset with limited space and millimeters, the Fresnel lens with small thickness, light weight and short focal length is really difficult to discard, and its poor accuracy can also be improved by computer modeling and CNC machining.

In the face of the rapid pursuit of the pursuers, the bees naturally did not dare to slack off, and the latest N7E is also equipped with this lens. The reason why it is half a beat is slow is because it takes a certain amount of time for bees to acquire integrated optical companies and then develop their own exclusive lenses.

The lenses of Bee Glasses 3 are independently developed and manufactured by Bee Optics, and this product is also hand-assembled by the latter's professional technicians. Although the automated assembly line and even the robot assembly line are efficient and low-cost, they are not as good as skilled and professional skilled workers in terms of precision control.

It is also because of the sweetness in BG3 that Bee Mirage continued to hand over the production task of N7E to Bee Optics, which also made the latter's nickname "Glasses Factory" more deserved.

The latter first attracted the attention of the outside world because it appeared on the packaging box of BG3, and it was also nicknamed the optical factory because of this. Then after the excavation of well-intentioned people, everyone found that this nickname seems to be very reasonable, and among the many companies that make up Bee Optics, there are indeed several that were originally engaged in the glasses business.

It is said that the gross profit of the glasses industry is scary, and the glasses with a purchase price of dozens of yuan are hundreds of dollars in the hands of consumers.

This is a fact, but it is only a partial fact, the actual situation is that the gross profit is high, but the net profit is small. As the old saying goes, it is "three years without opening, three years after opening". On the surface, a pair of glasses earns several times, but after deducting operating costs, the remaining net profit is actually not much. It is the equipment manufacturers and the landlords who really make money, after all, high-end glasses need luxury automatic glasses equipment and bustling and spacious stores to set off.

In fact, the first people who ate crabs did make money, but the guys who followed suit were tragic. After all, glasses are not consumable and not fast-moving, although heavy schoolwork and wonderful screens are still creating vision problems, but the market potential is far from as big as imagined.

When Bee was preparing to establish the optical department, it incorporated several such companies, and they were also industry insiders, so it was always faster to get started. Of course, much more money is spent on acquiring the BE business, which is the core business.

In addition to these two lenses, there is also an important element on this headset that is provided by Bee Optics and brings a great surprise to everyone.

After completing the running score, the N7E unsurprisingly achieved the second-highest result, significantly ahead of the N7, second only to the N that strange one.

The screenshot was saved, and then Yuan Yang put the headset on his head with his hand, and the reason was very high-sounding: "There is my eye data on the machine, which may save debugging time." ”

Then he was slapped in the face, and the prompt on the screen in front of him, "Visual detection and automatic adjustment is about to begin, please follow the prompts" is so dazzling and annoying.

The only thing that makes Yuan Yang feel relieved is that the synchronous display function of the external display is turned off, and it is not considered embarrassing if it is not looked at by Wang Datou.

As the detection process was carried out automatically, his chagrin was quickly replaced by surprise, and the mouth exposed under the headset opened wider and wider, and all of them were photographed by Wang Shan.

"I kind of understand why they design their own lenses," Yuan Yang suddenly shouted, because he had an earpiece in his ear, his voice was a little louder, which attracted the collective attention of everyone in the office.

Wang Shan felt embarrassed at this time, and hurriedly stood up and patted him. "Be quiet, what do you understand?"

"They've put a 3-film in the middle of the screen! The vision is great!"

At first, he didn't think about it, but when it came to the monocular test, Yuan Yang immediately noticed the difference, and the N7E's monocular field of view was wider, and suddenly threw the square field of view of other headsets into the ditch.

The human visual field is composed of the overlapping visual fields of the two eyes, the overlapping areas constitute the three visual fields of the human being, and the peripheral areas are the afterglow areas, and the whole visual field is somewhat like a huge "8" shape that lies down and bends around the head.

In order to facilitate production, the traditional R headset directly uses a large-size mobile phone screen as a display device, with a resolution of about 1920×1080, and only 960×1080 left in one eye, which can only be made into a square, and the actual appearance is a pillow-shaped polygon after eyepiece cutting.

This kind of picture is obviously not in line with the physiological structure of the human eye, and the field of vision that does not conform to human visual habits not only affects the sense of immersion, but also brings certain discomfort.

Also as a product that emphasizes a wide field of view, the N7E has also been specifically designed to address this issue, and their solution is to assist the display plus the naked eye3.

Naked-eye 3 is to attach a layer of grating to the screen, so that the left and right eyes can see different images respectively, and then mislead the brain to produce stereoscopic vision.

Nintendo's latest handheld 3S is based on this, which uses a slit LCD grating, which is called a "parallax barrier". In addition, there is also micropillar lens 3-film technology, which can bring better brightness and imaging effects, and is also used in some mobile phones that emphasize 3 functions.

It's just that this design has requirements for the viewing angle, and once you move your head, the 3 effect will disappear, and frequent movement may also cause vertigo. The international e-commerce giant Amazon's FirePhne uses eye-tracking technology to improve this problem, but unfortunately the excellent technology is no match for the lack of application and the bottleneck of battery technology, and finally becomes flashy chicken ribs, forcing Amazon to give up mobile phones and continue to sell e-readers.

The Bee N7E still uses the mobile phone screen, but a microlens3 film is pasted in the middle of the screen, but it is to open up the monocular field of view.

The combination of the 3 membranes and the eyepiece allows both eyes to see a wider range of images, bringing a wide field of view and slightly relieving R discomfort.

The human eye can only image the macular area of the retina in detail, and when we look at something, our eyes will automatically align it so that its image is projected on the macular area, so that we can see the target clearly. The parallax display of a normal headset can disrupt this coordinated "focus" pattern, known as visual convergence accommodation conflict. With the help of 3 membranes to widen the field of view, the eyeball has a larger range of motion, which can effectively improve this problem. As for the auxiliary screens on both sides, they also exist for this purpose, and they are an upgraded version of the LE scheme that has been tried before.
