600 MHz Dual-Balanced InGaAs Low Noise Photodetector

  In stock

The BPD600MA is an AC-coupled high-speed dual-balanced InGaAs photoreceiver. Due to its high transimpedance gain, its very low noise, and its bandwidth of 600 MHz, it is ideally suited for future ultra-high speed swept-source OCT systems with depth scan line rates up to above 1 MHz.

The BPD600MA comes in a rugged aluminum case with two FC fiber receptables and a 50 Ω coupled SMA output. It operates from a single 11-15 V DC supply.

OEM versions without a case are available upon request.

Main Applications

  • Ultra-high speed SS-OCT imaging
  • Interferometry
