Inphora T1¾, Series Calibrated LED Standards

IPR-DES2 series of T1¾ sized LED standards offer a convenient and accurate means of calibration or verification of LED spectroradiometers. Each standard incorporates a temperature regulator to stabilise the LED junction temperature and thus the intensity and spectral output from the LED. The LED drive current is typically set to 20mA with optional currents from 5 to 30mA. A choice of seven colour outputs are available across the visible and NIR spectrum. Port adapters and a body locking ring are available to mount the standards at the input port of an integrating sphere or LED intensity jig.


Calibration options include photometric and radiometric measurements of total flux and averaged LED intensity - condition A & B. Chromaticity, FWHM, peak and dominant wavelengths can be derived form the spectral radiometric data.


IPR-DES2 Model Range:
IPR-DES2 B Blue Standard
IPR-DES2 G Green Standard
IPR-DES2 Y Yellow Standard
IPR-DES2 O Orange Standard
IPR-DES2 R Red Standard
IPR-DES2 IR Infrared Standard
IPR-DES2 W White Standard

Other colours of IPR-DES2 products are available on request!
