|
This lens is a 3 panel LCOS design intended to utilize a high-index prism color management system such as the PBH56 ColorQuad system to project a 72 inch diagonal image with a 47 inch projection distance. At F/2.8 this lens exhibits less than 0.1% distortion, less than 3 microns of lateral color, nearly 90% illumination in the corners, 75% polychromatic MTF on axis at 45 cpmm, and maintains better than 50% MTF at 45 cpmm (average S&T). This is accomplished with common Schott glasses and plastic aspheres to achieve a high performance, low-cost projection lens option. Vertex-to-vertex length is 94 mm, and barrel diameter is approximately 47mm.
