(147kB PDF)

Description

The BPD1GA is an AC-coupled high-speed dual-balanced InGaAs photoreceiver. Due to its high transimpedance gain, its very low noise, and its bandwidth of 1GHz, it is ideally suited for future ultrahigh speed swept-source OCT systems with depth scan line rates up to above 1MHz.

The BPD1GA comes in a rugged aluminum case with two FC fiber receptables and a 50 ohm SMA output. It operates from a single 11-15V DC supply. OEM versions without a case are available upon request.

Typical Applications:

  • Ultrahigh speed SS-OCT imaging
  • Can be used single-ended as well

Features:

  • Bandwidth: 300kHz to 1GHz (5MHz to 1GHz on request)
  • High transimpedance gain: 3500 V/W (1550nm)
  • Low noise: Typically -130 dBm/Hz noise level
    NEP 20 pW/sqrt(Hz) (at 1550nm)
  • Wavelength range: 1000nm to 1700nm
  • 11-16V single supply
  • Input: FC fiber receptables
  • Output: 50 ohm SMA plug
  • Damage threshold: 10mW
  • Reasonable pricing (contact wieserlabs.com for a quote)
