The periscope lens is made of high refractive index glass and is processed into a right triangular or customer required shape. It is used for periscope imaging or emitting ends, turning the incident light by 90 degree or customer required angle, and provides more design space for camera or transmitter module in the length direction.
Technical characteristics and advantages:
Easier mass production
processes includingcold working, coating and printing.
Minimum surface accuracy < 0.1λ
Advanced coating and printing
Mobile phone camera
3D camera transmitter module
