Method

Array spectroradiometry with integrating sphere

Precise measurement of luminous flux, color coordinates and spectra via integrating sphere – ideal for LED and display characterization.

Equipment

CAS 140D array spectroradiometer and  ISP1000 integrating sphere with 1m / Instrument systems, MK350S handheld spectrometer / UPRtek

Method

Together with the remote controlled current and voltage sources, power meters and temperature controllers all light sources with low and high radiation intensities can be characterized from 300 nm to 1100 nm. The mobile spectrometer is useful for measuring flicker, blue light hazard, illuminance and human centric lighting related parameters directly on site.

Expected Result

Accurate measurements of radiometric, photometric and colorimetric parameters to characterize all types of light sources.

Case Study

A luminaire manufacturer wants to evaluate prototypes.
