glg goniospectrometer glg 8-850 Kompaktowy system do pomiaru przestrzennego rozkładu światłości, strumienia świetlnego i barwy light intensity distribution

A compact system for measuring light intensity distribution, luminous flux and color.

The easy-to-use GL Optic system combines the functionality of a goniophotometer with the features of a spectroradiometer to measure the luminous flux, determine the light intensity distribution values of colorimetric parameters required by international standards.

The new GLG 8-850 goniometer is a top-of-the-range benchtop goniometer designed to measure LED modules and smaller luminaires and to test components.
The automated system allows to measurement of devices weighing up to 8 kg and with a diameter of 850 mm.  The system with computer and GL Spectrosoft add-on software, enables measurements with an angular resolution of 0.1° and in the angular range of the C axis and λ +/- 180°.

Small in size, big in capability

Don’t let the size fool you. GLG 8-850 offers the ability to measure not only LED modules or small luminaires, but also vehicle lamps, thanks to the optional Type A conversion kit. The included lasers allow precise positioning of the DUT on the goniometer and measurement of the distance to the measuring instrument. In addition, the goniometer can be equipped with a temperature stabilization module.

Compliance with international standards

GL Optic’s devices are constantly updated to work in accordance with worldwide standards. Compliance with CIE S025/E:2015 and IES LM-79 ensure, that the results obtained can be used to sell products worldwide.

Accelerate product development

There is no need to build a large laboratory. The compact size of the GLG 8-850 goniometer, the intuitive interface software and the best price/performance ratio is a great basis for starting your own measurements. Instead of ordering measurements from external laboratories and wait for results, now you can have them done in minutes!

GLG 8-850 Lightweight Goniometer Application

Build Your Competitive Edge

LED lighting is becoming increasingly competitive and the available technology and components are changing rapidly. Developing and evaluating new modules and lamp models is a constant challenge for manufacturers and importers. Our fully automated, compact light goniometer instrument supports development teams and product testing laboratories that need to measure the light intensity distribution of LED products.

A large, expensive laboratory is not necessary if you want to measure smaller products and components. The GL Gonio Spectrometer GLG 8-850 can be used in a small darkroom or even in a dedicated test station and deliver professional photometric and colorimetric characterization of LEDs. A spectroradiometer and a user-friendly analysis software are needed to make the system complete. Start testing your own products and build your competitive advantage based on quality and knowledge.

Detailed tests and reports

Most goniophotometers on the market require highly trained and experienced technicians to deliver the results you need. The GLG 8-850 goniometer has been designed to bring the capabilities of any company closer and constructed as a practical, everyday solution for engineers and technicians. The plug-and-measure nature of the system simplifies complex measurement procedures. Simply install the lamp on the mechanical board, align it with the available laser alignment tool, set the parameters and you are ready to measure the intensity distribution. The system automatically rotates and the high-speed photometer measures the DUT in on fly mode and then the software presents the results in a fully customizable report.

Photometric files and more

GL Spectrosoft can easily generate light distribution diagrams, customized reports as well as IES and LDT photometric  files. With the spectroradiometer as the primary detector, the GLG 8-850 goniosystem provides all colorimetric values such as CCT and Duv, CRI and Rf (TM-30 2015) MacAdam Ellipses, Angular Color Uniformity and more. This is simply not available in standard light goniophotometer systems.
