Chapter 2 Description
The PDA20CS2 is an amplified, switchable-gain, Indium Gallium Arsenide
(InGaAs) detector designed for detection of light signals ranging from 800 to
1700 nm. An eight-position rotary switch allows the user to vary the gain in 10 dB
steps. A buffered output drives 50 Ω load impedances up to 5 V. The PDA20CS2
housing includes a removable threaded coupler (SM1T1) and retainer ring
(SM1RR) that is compatible with any number of Thorlabs 1” threaded
accessories. This allows convenient mounting of external optics, light filters,
apertures, as well as providing an easy mounting mechanism using Thorlabs’
cage assembly accessories.
