The MOGLabs PDA030 is an amplified silicon photodetector designed for demanding low-noise applications such as Pound-Drever-Hall optical cavity locking. It provides high bandwidth, high quantum-efficiency and low noise photodetection in a convenient mechanical enclosure with industry-standard connectors.
The 50Ω impedance signal is provided via a BNC connector that is isolatetd to help eliminate ground loops via the optical table. Power is via a Thorlabs-compatible M8 connector, which can be supplied by the MOGLabs FSC fast servo controller or a Thorlabs LDS12B. Optical tubes, filters and lenses are easily mounted using the standard SM1 threaded ring.
