2016 VR head sales total 6.3 million Samsung 4.5 million sales top
Today, according to technology website VentureBeat, a market research company Super Data published a research report that in 2016, global virtual reality headline sales were 6.3 million units.
According to the report, Samsung Gear VR sales were estimated at 4.5 million units last year, and Sony PlayStation VR ranked second in sales of "approx. 1 million units." This means that the combined sales of virtual reality heads from Oculus, Google and HTC is about 1 million units. The report shows that HTC’s Vive sales are “more than 400,000 unitsâ€, which exceeds Facebook’s Rift.
The report also pointed out that "Oculus has shown a strong interest in games and social applications, so the popularity among consumers is more important for Rift. HTC Vive is more favored by corporate developers."
Samsung is the only company to disclose head-to-head sales of virtual reality, saying that Gear VR has sold 5 million units.
Cylindrical lens is mainly used to change the design requirements of imaging size. For example, convert a point spot into a line spot, or change the height of the image without changing the width of the image. It can be used in linear detector lighting, barcode scanning, holographic lighting, optical information processing, computers, and laser emission.
Cylindrical mirrors are mainly divided into plano-convex cylindrical mirrors, plano-concave cylindrical mirrors, double-convex cylindrical mirrors, and double-concave cylindrical mirrors. Plano-convex cylindrical lens will focus the incident light on the line with a positive focal length. It consists of a flat surface and a convex cylindrical surface. It is often used to gather parallel or divergent light beams onto the line or change the aspect ratio of the image. A plano-concave cylindrical lens is composed of a flat surface and a concave cylindrical surface, and its focal length is negative. It is often used to gather parallel or divergent light beams on a line or to change the aspect ratio of the image. United Optics provides non-coated, anti-reflection coated cylindrical lenses. Antireflection coating options include UV, VIS, NIR, and SWIR. Germanium, silicon, or zinc selenide substrates are suitable for infrared applications, while fused silica is suitable for ultraviolet applications. Optical cylindrical mirrors are also widely used in high-power laser systems and synchrotron radiation beam lines. At the same time, the requirements for cylindrical mirror parts are getting higher and higher, especially in the cavity of high-power laser resonators and long-distance line interference. High-precision testing instruments and devices such as instruments.
