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 an isolated BNC connector that helps eliminate ground loops via the optical table. Power is easily provided via Thorlabs-compatible M8 connector, including directly from the MOGLabs FSC fast servo controller. Optical tubes, filters and lenses are easily mounted using the standard SM1 threaded ring.
