We offer a range of high quality Transfer- and Calibrationtandards to calibrate spectrometers and radiometers, for spectrale irradiance ([W/m²/nm]) in the UV/VIS/NIR range and photometric units ([lm], [cd]). They are traceble to PTB or NPL.
Our Quartz-Halogen- and Deuterium standards are produced as single lamps and complete systems including lamp holders and very stable, temperature compensated, constant current powersupply.

Wavelength range: 200 - 2500 nm.


Transfer Standard QTH: Labor/Transportable

Portable spectral irradiance transfere standard (Halogen Lamp, 200 W), based on the developement of the PTB (Physikalisch Technische Bundesanstalt, Braunschweig). Technical improvements allowe a simple and quick change of the lamp by up keeping of the original lamp certificate.

Wavelength range: 250 - 2500 nm.

Transfer Standard D2:

This calibration standard for spectral irradiance (Deuterium Lamp, 30W) is based on the developement of the PTB (Physikalisch Technische Bundesanstalt, Braunschweig).

Wavelength range: 250 - 350 nm.

LED-J1019: LED Transfer Standard

LED Transfer Standard for photometric and colorimetric units, based on the developement of the PTB (Physikalisch Technische Bundesanstalt, Braunschweig).

Units: luminous flux [lm], luminous intensity [cd], dominant wavelength

Calibration Standards

The accuracy of any spectroradiometric measurement system can only be as good as that of the standard source used for calibration. We manufacture a range of sources calibrated in our laboratory using NPL calibrated versions of the same product.

The following table is a representative but not complete list of devices available:
Product Standard of... Wavelength-range Units parameter
SRS8 Spectral Radiance 380-800nm mW/(sr.m².nm) Luminance (cd/m2)
