Tir Optical Glass Prism with Coating@Vis Black Painted

26 Nov 2021

Specification:

Projector prism 
Optical material 
High precision

The main function of TIR bonded prism is to divide the illumination path from imaging path,that also called as incidence light and outgoing light of the DMD components in DLP system. Using TIR prism means more simple optical path design and better image quality.

Material BK7, H-K9L   ,B270,Fused silica, etc
Dimension Tolerance ±0.02mm
Angular Accuracy   ±5"
Surface Quality 20/10
Surface Accuracy λ/10
Clear aperture >90
Coating Reflective Coating, Polarizing Coating, AR Coating,Dichroic Coating,   Filtering Coating, Phase Coating.

1,The imaging path can assure high transmittance ratio between -9.5°~14.5°, for example at 0°,can assure T≥95%.

2,The bonded air gap can be controlled between 0.005-1mm according to customer requirement.And the tolerance for 0.005-0.01mm range can achieve ±0.003mm.

3,Fastness of the bonding:Does not peel off when under the 500N force from outgoing surface.

4,Black matt paint available on appointed surface or area. Advantage:cost under well control, stable quality level, assure the guaranteed service for customer.
