Si Switchable Gain Detector

Chapter 2 Description

The PDA100A2 is an amplified, switchable-gain, Silicon (Si) detector designed
for detection of light signals ranging from 320 nm to 1100 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 PDA100A2 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. Also included is a ±12 V power supply.
The components inside this instrument are ESD sensitive. Take all appropriate
precautions to discharge personnel and equipment before making any electrical
connections to the unit.
