Mer-VRB140P/Q
Mer-VRB140P/Q is a VR single-double-bian folding detection lens designed for optical performance detection of VR equipment and modules. It has an ultra-large field of view angle of 140°×105°. It adopts an innovative folding design to avoid interference with the object to be tested, and provides high-precision, high-efficiency and high-stability solutions for VR research and development, production and quality control.
Core advantages:
●Binocular detection of optical performance of VR module
●140°×105° ultra-wide angle
● The outer diameter of the machine is smaller than the distance between the pupils of the human eye
● Ultra high resolution
●Single full inspection
Features
VR detection lens Mer-VRB140P/Q has many core technical advantages:
Full coverage detection of binocular FoV
Mer-VR140P/Q can obtain a monocular field of view of 140°×105° at one time. Compared with the same type of binocular detection lens, the obtained field of view data is more comprehensive to avoid missed inspection.
Innovative design
The innovative folding design is adopted, and the folding position is farther away from the pupil. While avoiding interference with the headset, it reduces the space required for detection and lens torque, which is more conducive to improving the stability of production line detection.
high resolution
This lens has a higher resolution, which can simulate human eye imaging more clearly, and obtain better image details and image quality.
Ultra-low stray, ultra-high transmittance
The lens coating was optimized, and the overall reflectivity of the lens was reduced by 12% compared to the competitors, and it only had ultra-low stray light that could be distinguished by human eyes. During the detection process, the stray light situation of the VR device or module can be more accurately judged.
Small size, saving detection space
The size of this lens is better than industry indicators, and it finds the best balance between performance and size. While ensuring that the lens optical parameters meet the testing needs, it minimizes the lens size to the maximum extent, facilitates installation and installation, and makes inspection more flexible. The aperture can be replaced to meet the detection needs in different scenarios.
