Abstract
A near and a mid infrared imaging camera for the NGST are presented, which were studied under ESA contract. Imaging in the 1 to 5 microns domain, possibly extended to 0.6 microns is a strong requirement for the core programs identified for NGST. Our compact near-IR camera design emphasizes simplicity with a single optical train covering a field 6 X 3 arcmin2 with a fixed spatial sampling of 0.03 arcsec/pixel on a 12 k X 6 k detector array. Three filter wheels allow for broad band and narrow band imaging. A mid- IR camera on NGST will be capable of carrying out aspects of many programs in the DRM. In addition to mid-IR is relatively unexplored at the spatial resolution and sensitivity NGST will be capable of, and so there is great potential for serendipitous science. A compact mid-IR camera design is presented covering a field 2.5 X 2.5 arcmin2 in the spectral range from 5 - 28 micrometers with two optical channels and a critical spatial sampling of 0.075 arcsec at 5 micrometers and 0.15 arcsec at 10 micrometers wavelengths.© (2000) COPYRIGHT SPIE--The International Society for Optical Engineering.
