Focussing Image Slicers: Refractive and Reflective
Abstract
A number of design options for image slicers for NGST and Gemini are being investigated. These image slicers are all of the focussing type and both refractive and reflective solutions are being explored. One such device, an image slicer that focuses 10 slices on a spectrograph slit is now in operation at the McMath Solar telescope. It consists of three lenslet arrays, and additionally acts as a focal reducer and provides correction for astigmatism of the telescope. A combined refractive and reflective slicer designed for use on NGST delivers near-diffraction limited images for up to 40 slices.
