Wide-Field, Two-Stage Optical System
Proposed telescope offers wide field of view, yet relatively inexpensive to manufacture. Design, in form of three Schmidt cameras, offers 10-degree strip field of view, single large-diameter collecting aperture, four spherical mirrors, and two diamond-turned aspheric mirrors in relatively compact configuration. Transference of large-diameter Schmidt corrector plate to smaller element makes this wide-field optical system suitable for application of two-stage optics theory. Concept enables cost-effective implementation of large-diameter optics by relaxing fabrication requirements.
