Spectroradiometers

Spectroradiometry

A spectroradiometer functions in a similar way to a photometer or colorimeter but measurements are performed spectrally and the photometric and colorimetric properties are computed. For narrow band sources such as LEDs, discharge lamps, CFLs and LCDs, a spectroradiometric measurement yields much more accurate results. Also, spectral measurements are the only way to determine the colour rendering performance of a light source. We offer spectroradiometric instruments that can measure spectral radiance (W/m2.sr.nm), spectral irradiance (W/m2.nm), spectral radiance intensity (W/sr.nm) and spectral radiant flux (W/nm).

Spectral Radiant Flux	Spectral Irradiance & Intensity	Spectral Radiance


Integrating sphere and hemisphere ("Half Moon") spectroradiometers are used for measuring the total radiant flux from light sources. With sphere sizes from 15cm to 3.0m, we can accomodate almost any size of light source or luminaire. Part of the modular Labsphere spectroradiometer system that includes accessories for spectral irradiance and LED CIE 127 average intensity measurements. » More	Spectroradiometers with collection optics for measuring the spectral irradiance, intensity and colour of light sources. Choose from the USB2000+IRRAD modular spectroradiometer system or the fullly portable JAZ Light Meter that combines the convience of a handheld photometer with the accuracy of a laboratory spectroradiometer. » More	The CS-2000 is a spot spectroradiometer that performs measurements of the spectral radiance, luminance and chromaticity of light sources and displays. With a sensitivity of 0.003 cd/m2 and exceptionally low stray light performance, the CS-2000 is capable of measuring contrast ratios of up to 100,000:1. » More
