InGaAs Photodiode with NIST Traceable Calibration

FGA21-CAL - InGaAs Photodiode, Ø2 mm, Calibrated from 800-1800 nm

Thorlabs offers five photodiodes, with NIST traceable calibration, that ship from stock. These include one Indium Gallium Arsenide (InGaAs), two Silicon (Si), and two Germanium (Ge) photodiodes.

Calibration Features:

Responsivity Measured Every 10nm Over the Spectral Range of the Photodiode
Measurement Uncertainty ±5%
NIST Traceable
Each photodiode will come with its own data table and graph of the responsivity vs wavelength

InGaAs Photodiode with NIST Traceable Calibration

One NIST traceable calibrated InGaAs photodiode is available from stock. InGaAs photodiodes are sensitive in the near infrared spectrum from 800-1700nm. The FGA21-CAL has a PIN structure that results in fast zero bias Rise / Fall times. For detailed information about its specifications please see the Specs tab.
