The 750 Series Laser Rangefinder Receivers are designed for laser ranging applications in which high sensitivity and fast recovery are required. The hybrid versions are designed to meet MIL-STD-883D requirements. Either a silicon avalanche photodiode (APD) or an InGaAs PIN photodiode or APD is available to detect 1.064µm or 1.55µm wavelengths. Different receivers also are available to accommodate pulsewidths ranging from 0.5ns to 30ns FWHM.
Data Sheets (PDF Format) are available for models listed below.
