Pro Lite Technology

Light Measurement

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. Not sure what you need? Either review our applications area, use the table below or contact Pro-Lite for informed assistance.

Goniophotometers are used to measure the angular intensity distribution and beam angle from lamps and luminaires (and for creating standard photometric data files), while for displays they measure the angular luminance variation and view angle.

  An imaging photometer or  colorimeter is a powerful, CCD-or CMOS-based instrument that provides for vastly increased productivity compared with ‘spot’ luminance meters. An imaging photometer can measure the illuminance, luminance or colour millions of points simultaneously. Our latest models feature sensors with up to 12 mega pixels for enhanced image quality and defect detection capabilities.

Labsphere 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 lamp and reflectance standards for calibrating integrating spheres, 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.

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.
