Description: The PDA series photo detectors are amplified photodiodes in a compact package. A wide bandwidth, low noise
amplifier boosts the output of the high-speed PIN photodiodes for detection of low-level signals. Connectorized
fibers can be easily attached to the PDA using one of the fiber adapters.
Thorlabs PDA400 Switchable Gain InGaAs Photodetector
The PDA400 adds near-infrared response and adjustable gain to the selection. A large 1mm diameter InGaAs
photodiode provides ease of use. Like its cousin, the PDA55, a 5-position rotary switch allows the gain to be
increased from 1.5 x 104 V/A to 1.5 x 106 in precise 10dB increments for repeatable measurements. The PDA400 has
a 10MHz bandwidth at the minimum gain setting.
This unit has the following features:
High-Speed Pin Photodiode
Low-Noise Wide Band Amplifier
Spectral Range: 800 to 1800nm
0 to 10V Output
New Low-Profile Housing
Includes Threaded Mount for 1" (25mm) Optics
