Mer-AR70D
The AR detection lens Mer-AR70D adopts an innovative optical design, which is specially optimized for the optical performance detection and production process of AR equipment and modules. This lens accurately simulates the imaging characteristics of the human eye, can truly restore the display effect from the user's perspective, and provides high-precision and high-efficiency solutions for the research and development, production and quality control of AR products. It has the following core advantages:
● Accurately simulated visual imaging of human eyes
●The field of view angle is up to 70°× 66°
● Ultra-low stray, high transmittance
●High stability focus
●High resolution
● The lens size is small
Features
AR detection lens Mer-AR70D has many core technical advantages
High stability focus adjustment
The focus sensitivity of Mer-AR70D is 0.75mm/ring, and the focus sensitivity is low, making it easy to find the best image surface; it can be locked after adjustment, so that the lens can be automatically defocused during use.
high resolution
This lens has a higher resolution, up to 0.4@200lpmm, 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 has been optimized, and the overall reflectivity of the lens is reduced by 12% compared to competitors. Therefore, the lens only has ultra-low stray light that is lower than that of the human eye. During the detection process, the stray light variable introduced by the lens can be eliminated, so that the stray light situation of AR equipment 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
