RGB Prism(Philips Prism)

RGB Prism(Philips Prism)

 

The RGB (Philips)Prism is designed for reflective LCOS Projector, matrix camera applications, and is well-suited to fast lenses imaging onto three CCD/CMOS sensors.
Foctek has developed the unique thin air-space (8um+/-2um) cementing technique for this prism, which allows Foctek to custom-made high precision Philips Prism for the customers.
