A Stanford/NIST collaboration is developing an imaging detector suitable for IR/optical/UV astronomical observations based on the Transition Edge Sensor, a cryogenic quantum microcalorimeter. Currently, the 32 pixel detector can in time and energy resolve single photons with high event rates ðDto1 ms and DE FWHM $0:16 eV at 2.33 eV and more than 10 kHz/pixel). We report on current progress with the first imaging TES instrument, focusing on recent advances in instrumentation including focusing, reflection masking and infrared filtering.
