Balanced Photodetector
OCT and sensor systems require high performance balanced photodetectors to increase system signal to noise ratio. The BPD-002 is specially designed for use in research and development, with ease of use and high performance as the primary design goals. The device is fully enclosed in a compact, sturdy aluminum 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 trans-impedance gain larger than 30K and a saturation power larger than 130 µW, the BPD-002 is ideal for integration into laboratory or commercial OCT, fiber sensor, and high performance optical measurement systems.
