High efficiency inexpensive 2-slices image slicers

摘要

Image slicers are widely used in astronomical instrumentation to increase the resolving power of spectrographs with themaximum throughput. However, the manufacturing costs are usually significant. This paper describes new image slicersimple designs. They provide only two slices but with high throughput and low cost manufacture process. Twoprototypes have been evaluated and their performances are reported.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
