Scanned Lidar & Laser-ranging Photoreceivers (InGaAs APD)

Our laser-ranging photoreceiver products—which include custom pulse detection and processing circuits—achieve the state-of-the-art sensitivity that enables reducing laser-pulse-energy requirements by a factor of at least 20 compared to PIN photodiode receivers and a factor of at least five compared to competitor APD photoreceivers.

To achieve the stable gain required for the highest-sensitivity imaging capabilities of our APD photoreceivers—especially at higher temperature operation, where impact ionization would otherwise decrease, leading to unstable gain witnessed as noise—temperature is monitored thousands of times per second and APD bias is optimized by a microcontroller that is integrated into the TO-8 package.

To give system designers a turnkey laser-ranging solution for thermal, electro-optical, and optical scope integration, these photoreceivers are available with optional laser ranging control electronics to control a user-provided laser. The result is a compact, lightweight highly-reliable ranging module with excellent performance.

APDs (InGaAs)

Unlike common APDs, which have noisy avalanche gain, our custom-engineered, industry-leading advanced InGaAs APDs offer extremely low dark current and half the excess noise, providing superior range and false-alarm performance. These APDs are sensitive over the 950 – 1750-nm spectrum, including the eyesafe spectral region beyond 1300 nm.

Deschutes™ Series

Key Product Features

  • Very low excess noise (k < ~0.2)
  • Moderate gain (M < 20) and low dark current is optimal for low-bandwidth optical receivers where only moderate gain is required to overcome electronic noise
  • Available with collection areas from 30 μm to 500 μm in diameter
