Cameras for infrared interferometry from Armstrong Optical

With the greater use of thermal imaging in military, homeland defence, security and surveillance applications the need to test infrared lens systems to ensure that they meet demanding specifications has never been more widespread. One of the easiest and most diagnostic lens testing techniques in use is interferometry and Armstrong Optical Ltd now have the capability to offer camera systems for all the common infrared wavebands.

As well as the usual 8-12µm sensitive cameras for use with a 10.6µm (CO2) laser source, Armstrong Optical have just added into their product portfolio a 3-5µm sensitive system, for use with 3.39µm (HeNe) laser source, and a 3-12µm sensitive system, for dual band applications. Cameras for near-IR testing applications are also available on demand.

All of the cameras have been selected for their ease of retrofitting into existing infrared interferometry systems and complement the range of interferometry accessories available from Armstrong Optical such as phase shifting kits and fringe analysis software.
