Integrating Sphere Photometers

Integrating Sphere Photometers from Pro-Lite

Integrating sphere photometers are used for measuring the total luminous flux from lamps, LEDs and luminaires. We offer integrating spheres from 2 to 76" (5cm to 1.93m) diameter, which means that we can accomodate almost any size of light source. For small sources and fibre optic illuminators, we have a portable 2" sphere photometer. For larger samples, we offer interior access integrating spheres with diameters from 10 to 76".

Integrating sphere photometers record the total flux from a light source in lumens; for improved accuracy with narrow band sources such as LEDs, or if you need to measure the spectral power, chromaticity or colour rendering of your light source, you will need an integrating sphere spectroradiometer (see: integrating sphere spectroradiometers).

Labsphere HLMS-200P Portable Sphere Photometer

HLMS-200P Portable Sphere Photometer

The Labsphere HLMS-200P is a convenient, hand held photometer with 2-inch integrating sphere. With a 0.5-inch input port diameter, the HLMS-200P is perfect for measuring the total luminous flux in lumens from individual LEDs, small lamps and fibre optic illuminators.
