Photometric Measurement Systems

Complete Photometric Characterisation from Goniophotometry to Spectroradiometry

Photometric measurement systems characterise the full light output of LEDs, luminaires, and lamps — spectral power distribution, luminous intensity distribution, colour rendering, and correlated colour temperature — to standards including IES LM-79, CIE127, and EN13032-1.

This range covers goniophotometers and goniospectroradiometers for luminous intensity distribution, integrating spheres from tabletop to 3-metre diameter for total luminous flux, CCD spectroradiometers for spectral and colorimetric measurement, and complete LM-79 compliant integrating sphere spectroradiometer systems combining all the equipment needed for full LED and luminaire photometric testing.
