Light sources for calibration

We offer two types of light sources for calibration: Pen-Ray line sources for the wavelength calibration of spectroscopic instruments and calibrated irradiance sources covering UV-NIR.

  • Narrow discrete spectral lines
  • PTB traceable calibrated Halogen and deuterium lamps

Pen-Ray line sources

For the wavelength calibration of spectroscopic instruments such as monochromators, spectrographs and spectral radiometers we offer Pen-Ray line sources. These are stable, low-pressure discharge lamps and produce narrow, intense lines from the excitation of various rare gas and metal vapors.

Calibrated irradiance sources, UV-NIR

For measuring spectral responsivity of spectrometers and radiometers we offer calibrated halogen and deuterium lamps as standards of irradiance. These are sources of known spectral irradiance.
