Excelitas ready to support demand for heated YAG-enhanced quadrant photodiodes.

  • Date: 9th October 2019
  • Company: Qioptiq

Intended for, amongst other applications, Munition guidance, Semi-Active Laser (SAL) seeker, Laser Spot Tracking (LST), and Laser seeker header, etc. Our extensive capability means we are ready to support both common cathode (N-type) and the continued support of common anode (P-type) seeker designs.  Heating increases performance while smaller active areas enable guidance for smaller weapons, such as smart grenades and mortars.

Eric Desfonds – Product Leader, said “Localized heating of the Silicon photodiode, while slightly increasing the noise of the photodiode, greatly increases the responsivity. Rapid heating allows faster locking-in from a farther distance and safer engagement distances for warfighters.” Beyond the standard catalog parts, Excelitas can provide further custom packaging, screening and qualification to meet the most stringent operating conditions, delivering ITAR-free and BAFA-free solutions.
