Ge Photodiodes with NIST Traceable Calibration

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.

Ge Photodiodes with NIST Traceable Calibration

Two NIST traceable calibrated Ge photodiodes are available from stock. Ge photodiodes are sensitive in the near infrared spectrum from 800-1800nm. The FDG03-CAL and FDG05-CAL are AR Coated for 1300-1550nm and are packaged in a can and on a square ceramic substrate respectively. For detailed information about their specifications please see the Specs tab.

FDG03-CAL - Ge Photodiode, Ø3.0 mm, Calibrated from 800-1800 nm


FDG05-CAL - Ge Photodiode, Ø5.0 mm, Calibrated from 800-1800 nm
