OCT and sensor systems require high-performance balanced photodetectors to increase system signal-to-noise ratio (SNR). General Photonics’ BPD-002 balanced photodetector module is specially designed for use in research and development, with ease of use and high performance as the primary design goals.
The BPD-002 device is fully enclosed in a compact, sturdy aluminium box with two optical input ports, a balanced RF output port, two 1 MHz monitor ports and a power supply port. With a bandwidth up to 200 MHz, a transimpedance gain larger than 30K and a saturation power larger than 130 µW, the BPD-002 balanced photodetector is ideal for integration into laboratory or commercial OCT, fiber sensor, and high-performance optical measurement systems.
