These are Type C/gamma goniophotometers with wide-ranging applications including luminaires, floodlights, streetlights, LED clusters, emergency lighting, flat panel displays and others.

The software has a step-by-step flow that makes testing easy, even for inexperienced users, and other software utilities make these systems powerful and advanced research and development tools.

PSI’s LF series integrating sphere photometers are widely regarded as excellent quality, robust equipment for industrial or laboratory applications.

Standard sphere sizes are 0.5, 1.0, 1.5 and 2.0m diameter, however other sizes are manufactured according to customer requirements.

PSI offers a variety of spectrometers to suit a range of applications. The most common type is the SP-3C real-time spectroradiometer for chromaticity measurement.
