Electronic projection system with polymeric film optical components |
摘要 |
An electronic projection system that includes specularly reflective optical components made of a multilayered polymeric material with a reflectivity of at least 96% from about 400 nm to about 700 nm, and a method for enhancing the optical quality of a projected image in a projection display device comprising the step of incorporating at least one specular mirror component in the optical train of the device.
