First fully adapted system for road lighting measurements according to the EN 13201: 2016 standard
Until the appearance of GL OPTICAM 3.0 4K TEC the measurement of luminance distribution was a tedious, time-consuming and costly process, requiring the participation of many people with specialist knowledge. The new system for imaging luminance measurements provides full measurement data necessary to calculate the luminance distribution of the selected road and area lighting standard compliance in seconds. Unlike other laboratory meters, GL OPTICAM 3.0 4K TEC is the world’s first solution fully adapted to field measurements.
It includes TEC unit for thermal stabilisation of the image sensor, which compensates for measurement errors resulting from changing temperature conditions. Its hermetic housing ( IP 54 ) is designed for field work and prepared for different weather conditions – even in the rain, without the fear of camera damage. In addition, it has a battery power source which relieves the operator of the need for power generators and portable power supplies when working outdoors. A set of included accessories makes it easy to determine the measurement field and complete measurement process.
Plug and Measure
Preconfigured and individually calibrated digital luminance camera system for immediate testing of luminance distribution. It is as easy as putting this instrument on the tripod in front of the lighting system and measuring absolute luminance level. The instrument can be used both in the field and laboratory.
Dedicated V- lambda filter
Each camera is equipped with the specially selected class A optical corrected filter to provide the highest quality of luminance measurements corresponding with the human eye sensitivity. Each filter is optimized for each CMOS sensor individually.
TEC controlled image sensor temperature compensates for measurement errors resulting from changing temperature conditions.
Adding spectrum and color
This new image luminance camera can be combined with our spectral instruments like GL SPECTIS 1.0 touch to expand the quality control with the colorimetric values like CCT, CRI and many more. Additionally it will also provide an automatic filter miss match correction procedure and support the measurements of multiple color LED devices testing.
