The PDA series of Amplified Photodetectors feature a wide range of photodiode plus amplifier configurations housed in compact, low profile packages. Detectors are available for use in the UV, visible, NIR, and MIR regions. The modules possess 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. Thorlabs offers a wide variety of BNC, BNC-to-SMA, and SMC cables, as well as a variety of BNC, SMA, and SMC adapters.
Each housing provides two 8-32 tapped mounting holes (M4 for - EC versions) centered on the detector surface for vertical or horizontal post mounting. In addition, all units include a removable threaded coupler that is compatible with most Thorlabs SM1- and SM05-threaded accessories. This allows convenient mounting of external optics, optical fibers, and apertures, while providing an easy mounting mechanism when using Thorlabs' cage assembly accessories. A 120 VAC AC/DC power supply is included (230 VAC for - EC versions).
Please Note: Due to limitations in the IC, the high speed amplifier used in these devices may become unstable, exhibiting oscillations or negative output if the power supply voltage is applied when the module is on. The unit should always be powered up using the power switch on the power supply or the unit itself. Hot plugging the unit is not recommended.
