The PDA36A is an amplified, switchable-gain, silicon detector designed for
detection of light signals over 350 to 1100 nm wavelength range. An eightposition 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 PDA36A 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 the Thorlabs cage assembly
accessories.
