The PDA25K Amplified Photodetector is housed in a compact, low profile package, and is designed for the detection UV and visible light. The module has a thin profile to allow access to light paths with a minimal footprint. All connections and controls are located perpendicular to the light path, providing increased accessibility. Amplification is provided by low noise transimpedance or voltage amplifiers that are capable of driving 50 Ohm loads. Signal output is via a BNC connector.
