A combination of two laminated prisms, a TIR prism effectively directing the incident light to DMD chip, the expected image is projected following the light beam reflected by DMD chip.
Applied in DLP® projection system, light path is changed by using TIR to save the space in optical engine and enhance contrast level of the system.
What We Achieved :
|Material||N-BK7, H-K9L or equivalent|
|Air Gap||10 +/- 2 μ , 5 +/- 2 μ or 3 +/- 2 μ|
|Operating Temperature||0 ~ 85°C|
|Remark||* In-house black-painting |
* Excellent parallelism control
* Precise gluing and cementing technique
* Excellent transmittance performance at required AOI angle
