Optical Standards

Calibration Standards from Pro-Lite

Our certified standards are used to calibrate spectroradiometers, colorimeters, photometers, reflectometers, spectrophotometers, remote sensing instruments and scatterometers. If you are measuring light sources, you'll need a lamp standard. If you are measuring the optical properties of materials, you'll need a standard of reflectance, or for larger tiles, a reflectance target. Calibrations are performed using transfer standards that are traceable to national or international standards.

Labsphere SCL-600 Spectral Flux Standard Lamp

Lamp Standards

This section includes standards of luminous and spectral radiant flux which are used to calibrate integrating sphere photometer and spectroradiometer systems. Also featured are standards of spectral radiant forward flux, and a standard of spectral irradiance and spectral radiant intensity for calibrating irradiance and intensity sensors.

Reflectance Standards

Standards of specular and diffuse reflectance for calibrating colorimeters, reflectometers, spectroradiometers, scatterometers, spectrophotometers and FTIR spectrometers. Our diffuse reflectance tiles are made of Spectralon and include standards of white & grey scale reflectance, colour, wavelength and fluorescence. For the IR (0.7-20µm) we also offer Infragold diffuse reflectance standards.

Reflectance Targets

Spectralon also forms the basis of our diffuse reflectance targets. Spectralon targets are available in sizes up to 60 x 60cm; non-standard sizes and larger panels are available to on a custom basis. For the IR (0.7-20µm) we also offer Infragold diffuse reflectance targets. Our targets are used to calibrate remote sensing systems and spectroradiometers.
