Measurement of Light
Pro-Lite provides a solution for almost any application in measuring the colour and brightness of light sources and displays. From a simple, inexpensive lux meter, to the world's most advanced imaging photometers, we have a light meter that you can rely upon to give you accurate, repeatable data. We also supply reference standards to calibrate your instrument and integrating sphere uniform light sources which are used to test and calibrate imaging and remote sensing equipment. Not sure what you need? Either review our applications area or contact Pro-Lite for informed assistance.

Goniophotometers perform angular analysis of light sources and displays. Our far-field goniophotometers are used to test vehicle lighting and road signs, while our near-field goniophotometers are used for testing flat panel displays and luminaires. Our source imaging goniophotometer generates Radiant Source Model files. The novel Imaging Sphere is an ultrafast goniophotometer.

Integrating spheres are used as directionally-insensitive collectors of light when combined with a detector. An internally illuminated integrating sphere emits a field of spatially and angularly uniform luminance or radiance which is perfect for testing and calibrating electronic imaging systems. Spheres are also used for measuring total reflectance and transmittance.

Certified standards for calibrating spectroradiometers, colorimeters, reflectometers, spectrophotometers, remote sensing instruments and scatterometers. If you are measuring light sources, you'll need a lamp or radiometric standard. If you are measuring the optical properties of materials, you'll need a standard of reflectance, or for larger tiles, a reflectance target.

The world's most popular spectrometers? Probably - over 120,000 have been sold since 1992 - but there can be no question that Ocean Optics CCD spectrometers provide for convenient, affordable spectral analysis. Applications include laser and LED testing as well as reflectance and transmittance measurements. Choose from spectrometers for the 200-1100nm and 900-2500nm ranges.

A spectroradiometer functions in a similar way to a photometer or colorimeter but measurements are performed spectrally. For narrow band sources such as LEDs 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.

An internally illuminated integrating sphere provides uniform radiance or irradiance for testing and calibration optical instrumentation. Uniform light source systems are used to perform flat-fielding and pixel gain normalisation of cameras and array detectors (CCD, CMOS). Other applications include calibrating photometers and remote sensing spectroradiometers.
