STIS2 is the visible detector of choice. With this detector, the field of view covers 1400 x 1400 pixels, but the full 2048 pixels can be used along the dispersion for spectroscopy. Pixel size is 15 microns. B, V, R, I filters are available 4. K is a clone of the UH8K with an expanded focal plane of 8K x 12K pixels.
Work is well underway on the dewar and shutter assemblies.
These are thinned, blue sensitive devices with significant Q.E. down to 3800 Angstroms. The exact number of devices, and their quality is still undetermined as the fabrication and testing is not yet complete. However, we feel fairly confident that we will be able to populate the camera with 12 reasonably good devices. While this 5. Results were encouraging, and no major flaws were noticed.
