High resolution, thermally stabilized, laboratory imaging luminance camera system.
Optical engineers and system developers are facing faster changes in design and complexity of backlit components in automotive, transportation, electronics and other industries. Improvement of user interface with the use of modern LED and OLED components makes the quality verification a challenge for development teams and QA/QC personnel. They all need reliable and accessible instruments for optical tests and measurements.
The GL OPTICAM 2.0 4K TEC is an Imaging Luminance Measuring Device designed to verify compliance and check performance of lighting components to support faster introduction of modern LED, OLED lighting devices. The optical performance of displays, backlit buttons and instrument clusters requires a dependable luminance testing solution. Developers, designers and quality engineers need to verify luminance uniformity, contrasts, luminance distribution and light leakage. With this new optical instrument all touch screen control panels, backlit buttons, displays, keyboards and indicating lights can be easily and precisely verified during the R&D and production stage.
The GL OPTICAM 2.0 4K TEC is a high resolution, laboratory performance optical camera system featuring a high resolution 9M pixel CMOS image sensor with a dedicated V-Lambda correction filter precisely adjusting the system’s sensitivity (response) to human’s eye sensitivity. Selection of high class lenses is available for this optical system depending on a specific luminance measurement requirements. The system features a unique RFID lens recognition* system and a thermal stabilization of the image sensor, which compensates for measurement errors resulting from changing temperature conditions. *patent pending

Drive Your Critical Requirements with Specialized Instrument
Automotive and household appliances electronics industries are the major drives of the development of the new GL OPTICAM Imaging Luminance Measuring Device – ILMD. The increased number of touch screens and complex instrument clusters puts additional demand on precise testing of lighting components. High resolution imaging system is required to evaluate luminance uniformity of fine backlit icons for instance. Also, when working with high resolution displays, an appropriate resolution of luminance measuring camera is required. This is why we decided to launch a new model of the luminance camera system with 9M pixel image sensor resolution. The GL OPTICAM 2.0 4K TEC is based on the new type of CMOS monochromatic image sensor from Sony combined with a class A, V-lambda correction filter and carefully selected lens. Each optical system from GL Optic includes factory calibration consisting of multi-step procedure ensuring traceability and laboratory accuracy performance.
Best-in-class optical system
Each camera system is equipped with an individually selected and calibrated optical correction filter optimized for the image sensor. Unlike mass produced digital cameras, GL Optic instruments are designed with the use of high quality glass filters and lenses from the leading suppliers.
The image sensor is thermally stabilized by TEC unit to improve stability and increase the dynamic range of the sensor.
A novel RFID Automatic Lens Recognition helps to change the system configuration automatically. This light camera luminance meter, supported by our GL OPTICAM SOFT analytical software, allows the user to set and measure different objects in no time. Simply plug this calibrated imaging luminance meter to your PC where you can monitor the image, set the parameters and measure the luminance simply by recording the image of the device user test of the luminance scene.
The analytical software will detect default areas of interest, show luminance level, histograms and will immediately display other useful data. The system helps to analyse specific details and regions and even provide necessary corrections. This instrument provides absolute luminance accuracy just like a typical laboratory device.
When colour matters
When the lighting fixture or electronic board is using different colour LEDs, the standard OPTICAM 2.0 4K TEC luminance meter can be combined with our GL SPECTIS 1.0 Touch spectral device to support luminance and colour test and evaluation. Our GL SPECTROSOFT features an option to combine the measurements from the luminance camera with the spectroradiometric measurement. As a result, we are able to provide the mismatch correction for luminance values to get the highest accuracy and provide all colorimetric and spectral data for the LED product under test.
Plug and Measure with RFID Automatic Lens Recognition*
Preconfigured and individually calibrated digital luminance camera system for immediate testing of light components and light device quality control. You can simply put this instrument in front of the lighting system and measure absolute luminance level immediately. The system automatically recognizes the lens and uploads the calibration file. Use this instrument in the laboratory, product testing and field measurements for lighting systems quality control. *patent pending
Improved optical resolution
When developing new complex optical system this precise 9M pixels resolution luminance measuring instrument will improve your R&D process. Now you can make faster decisions on modification and/or compliance.
This instrument is equipped with a TEC unit for thermal stabilisation of the image sensor, which compensates for measurement errors resulting from changing temperature conditions.
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.
Adding spectrum and colour
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 colour LED devices testing.
