Principle and function:

Its main function is to transfer R,G,B three primary color images, and combine them as a total chromatic image, then pass through the lens assembly projecting onto the screen.

Specfication:

1. Outer dimension:50×50×50~10×10×10,accuracy:±0.1.

 2. Surface form N=0.5~1

3. Angle of Reflective surface:±10″

4. Mismatch controled within:1μm

 5. Width of combined center reticle : 7μm

 6. Refractive index of 4 prisms bonded together within 0.00005.

 7. Coating characteristic: 420nm~680nm,Blue Rs(avg.)>95%,Green Tp(avg.)>97.5%,Red Rs(avg.)>95%,Difference of two coating surface  within 3nm.
