The RSAL1 is a high performance anamorphic add-on lens installed in front of digital projectors to convert them to a higher (wider) aspect ratio. The RSAL1 can be used for constant height 2.35:1 imaging as either a moveable lens (electronic vertical image stretch required for 2.35:1 content) or a fixed lens (both electronic vertical stretch and horizontal squeeze [for non-2.35:1 content] required).
Black aluminum and molded plastic housing with included black aluminum bracket.
Total lens weight with bracket of approximately 8.5 pounds (3.8 Kg).
Lens dimension without bracket is approximately 5.4" wide x 5" high x 7.6" long.
Large entrance aperture of 3.1" x 3.1" (4.3" diagonal) for maximum versatility.
Five element, 100% glass, patented, fully multicoated optical design corrected for chromatic aberration and astigmatism in standard home cinema environments.
Accepts even large beams and produces low distortion and exceptional image quality up to and beyond 1080 resolution at throw ratios down to 1.6 (image distance divided by pre-lens image).
Supports throw ratios down to 1.4 when used with smaller beams and curved projection screens.
No change in focus when moved in and out of the projection beam.
