LISA offers a wide variety of instrumentation and equipment to test and characterize cameras and sensors. Depending on the sensor type (CCDs, CMOS, EMCCDs, semiconductor arrays, photodiodes, microbolometers, etc.) the characterization procedure changes. Here, for simplicity, LISA characterization set-ups are divided according to the wavelength range response:

  • Near UV, Visible and Near IR (300 nm-1100 nm); CCDs, CMOS, EMCCDs, silicon photodiodes. 
  • Infrared: 
    • Short wavelength infrared range SWIR (750-1500 nm): InGaAs detector modules.
    • Middle wavelength infrared range MWIR (1-5 μm): MCT and InSb array detectors.
    • Large wavelength infrared range LWIR (8-14 μm): thermal sensor and cameras, microbolometers.

 

LISA has an extensive list of equipment to carry out measurements, make custom set-ups, and integrate adapted designs. Moreover, the Electronics Department providse some specific auxiliary facilities that complements the LISA lab. Finally, LISA supports cryogenic and vacuum systems in collaboration with the Mechanics Department. 

A summarized list of the available equipment is showed here below:
