Corner Cube Retro Reflector or Survey Prism operates on the principle of Total Internal Reflection (TIR). An incident beam will be reflected parallel to itself by the three roof surfaces. The reflection is insensitive to the incident angle, even when the incident beam enters the prism off normal axis, there will still be a strict 180deg reflection.
We are able to steadily control the complex reflecting error in the range of 2” (or 0 to -5”) and supply reliable silver (Ag) coating, Cu (copper) coating, aluminum (Al) coating and Anti-Reflect (AR) coating. |
