Defense and Aerospace Sensors
Excelitas has over 30 years of experience providing sensors for the accurate measurement and detection of light, heat, motion, and distance in mission-critical military and aerospace applications.
Excelitas offers a wide range of emitters and detectors for laser ranging and designating and proximity fuzing and laser warning systems, including the EXACTD series, detectors, and pulsed lasers. We also offer terminal guidance detectors for precision guided munitions and laser spot tracking, as well as emitters for target acquisition, ranging, and designation.
We address requirements with both standard (off-the-shelf) products and customer-specific designs customized to meet end-user requirements.

Avalanche Photodiodes
Excelitas offers Avalanche Photodiodes (APDs) on both Silicon (Si) and InGaAs materials. Si APDs cover the spectral range of 400 nm to 1100 nm and the InGaAs APDs cover 950 nm to 1550 nm. An Avalanche Photodiode (APD) provides higher sensitivity than a standard photodiode and is for extreme...
