  The Cambridge Infra-red Panoramic Survey Spectrograph (CIRPASS) is described.
This near-infrared (NIR) spectrograph has been used on the 8m Gemini-South
Telescope, the 3.9m Anglo-Australian Telescope (AAT) and the 4.2m William
Herschel Telescope (WHT). Its performance in both integral field mode and
multi-object mode is discussed and some scientific highlights are presented. A
multi-IFU system, which is currently under construction, is also described.
