GL OPTICAM 3.0 4K TEC Usage

Smart development programme

Working with Poznan University of Technology, the GL OPTICAM imaging luminance equipment was developed and implemented under the National Center for Research and Development Program. The project’s objective was to commercialize a measurement device that facilitates on-site assessments of luminance distribution. Though there are a lot of luminance meters on the market, all of them are made for laboratory use and aren’t really intended for measuring road luminance.

Using both spot luminance meters and an imaging luminance measuring device, the staff of the Poznań University of Technology’s Department of Light Technology and Electrothermal Energy has many years of expertise measuring brightness on highways. An objective evaluation of the road lighting installation performance is made possible by the use of an ILMD meter, which greatly simplifies measurement procedures and contributes to the acquisition of more trustworthy data.

Focusing on road lighting quality

Road brightness measurement is a difficult task. This system is ready to take measurements on the road at the location. The hermetic casing of the camera is designed to prevent mechanical damage to the lens and system. The supplied power pack and auxiliary devices enable professional field measurement, and the thermally stabilized sensor is prepared to operate in a variety of temperatures. It can be applied in many settings while preserving the precision and efficiency of the laboratory.

Measuring system that works outdoors

The system also comes with a reflective safety vest, a measuring wheel for distance measurement, a heavy-duty elevating tripod, an extra battery pack, and specially made measurement field markers. This is all assembled into travel-ready cases to form a transportable measuring stand.

Adding colorimetry

Our GL SPECTIS 1.0 Touch spectroradiometer and this luminance meter can be used together to perform colorimetric testing and evaluation. Combining the spectroradiometric measurement with the luminance camera measurements is possible with our GL SPECTROSOFT. This allows us to provide complete colorimetric and spectral data for the LED product that is being tested, as well as mismatch correction for brightness values to obtain the best accuracy.

GL OPTICAM 3.0 4K TEC Features

Plug and measure

Digital luminance camera system that is individually calibrated and preconfigured for instantaneous luminance distribution assessment. Measuring the absolute brightness level is as simple as placing this device on the tripod in front of the lighting system. The device is applicable in both laboratory and field settings.

Dedicated V- lambda filter

A carefully chosen class A optically adjusted filter is fitted to every camera to ensure the best possible brightness measurements that match the sensitivity of the human eye. Every filter has a unique optimization for every CMOS sensor.

Thermal stabilisation

Temperature variations in the image sensor are compensated for by the TEC-controlled image sensor temperature.

Adding spectrum and color

The quality control can be expanded with colorimetric values such as CCT, CRI, and many more by combining this new picture luminance camera with our spectrum instruments, such as GL SPECTIS 1.0 Touch. It will also enable the measurements of multiple-color LED devices and offer an automatic filter miss-match adjustment process.
