With the Lighting industry we focus on manufacturers of lighting products like lamps and leds. But also the companies involved in testing and validating lamps and leds, and assembling these products in streetlights, solar simulators and more.
Since lighting products emit light, the connection with spectroscopy is easily made. In this industry spectroscopy is mostly used for quality control.
Radiometry and Photometry are important topics. The comprehension which parameters need to be determined is critical for the selection of the correct setup.


Radiometry deals with the measurement of all optical radiation including the visible portion of this radiant energy.
Within the field of radiometry different parameters can be defined, such as: irradiance, radiant flux and radiant intensity. Radiometry measurements can be done in the UV, VIS and NIR wavelength ranges.


Photometry relates to visible radiation alone, just as the response of the human eye. Like with radiometry, in photometry also different parameters can be defined. Such as Luminous flux, Luminous Intensity and Illuminance.

Other Parameters

Aside the above measurement parameters often specific parameters are used to describe the quality of a lighting product. Parameters describing the color, dominant wavelengths and calculated color temperatures are needed to specify and document the lighting products.

In order to achieve the above Avantes offers aside a wide selection of spectrometers, the needed accessories like integrating spheres and cosine correctors.
Often the system needs to be Intensity calibrated. Avantes offers in-house calibration services as well as field calibration sources.
