GL PRODUCTS

Accurate. Reliable. Practical. High performance light measurement products designed for everyday applications

Light Measurement Simplified

At GL Optic, we understand light measurement challenges because we come from the technical lighting industry. We know that for an instrument to produce dependable light measurement results, its precision is as critical as its reliability. But it doesn’t stop there. Practical, high value solutions are needed to bridge the gap between reference labs and real world challenges.

For over 40 years our parent company JUST Normlicht has been a leading supplier of standardized light solutions. As an expert in the lighting industry, we have managed to combine German know-how with a fresh and innovative approach to spectral light measurement.

Fast and Precise Results

Accurate light measurement data is no longer exclusive to experts – our individually calibrated measurement tools deliver fast and precise results, with intuitive and easy to navigate software. All traceable to National Laboratory sources and best practices.

Complete Light Measurement Solutions

We provide complete light measurement solutions that deliver the results you need rather than managing a set of individual components on your own. Our commitment is to deliver fully integrated color and spectral measurement tools that will help companies develop higher quality products, faster.

Spectrometers

Spectrometer is an essential tool in every quality control and research and development departments of lighting manufacturers companies. It enables measuring basic quantities, such as light intensity (illuminance), luminous flux and color temperature and is neccesary to prepare detailed spectral analysis.

GL SPECTIS 1.0

Precise light measurement technology in a handy format, configurable with a range of accessories.

GL SPECTIS 1.0 Touch

Highly efficient and user-friendly intelligent spectrometer. Leading accuracy in its class and unrivalled flexibility thanks to a wide range of accessories.

GL SPECTIS 5.0 Touch

The GL SPECTIS 5.0 Touch spectrometer is equipped with a Hamamatsu CCD sensor (back-thinned), which guarantees high stability even with long integration times.

Integrating spheres

Integrating sphere is indispensable when it comes to measuring the luminous flux. The range of our interating spheres will meet the needs of professional laboratories and lighting manufacturers as well. They are easy to operate and flexible for adaptation to individual consumer needs.

GL OPTI SPHERE 48

It measures the radiant power, luminous flux, color temperature, color coordinates and color rendering index (CRI) of LEDs.

GL OPTI SPHERE 205

Provides an automated, user-friendly alternative for measuring the luminous flux and radiant power of LEDs and other small light sources.

GL OPTI SPHERE 500

Simple measurement of luminous flux and energetic radiation of LEDs and LED modules.

GL OPTI SPHERE 1100

Developed for measuring the luminous flux and energetic radiation of medium-sized LED luminaires and large LED modules.

large integration spheres

Diameters of 1.5 m, 2 m or 3 m ensure that the sphere is optimized for measuring large lighting devices.

Goniometers

Goniometers are used to determine the light distribution curves. They are designed to rotate the luminaire to collect data, using photometers and spectrometers, on which direction the light from the luminaire falls.

GL GONIO SPECTROMETER GLG 8-850

The GLG 8-850 goniometer is a high class desktop goniometer designed for the measurement of LED modules, component tests and smaller lighting luminaires.

GL GONIO SPECTROMETER GLG 30-1800

With a maximum load of 30 kg and a maximum diameter of 1800 mm, the GLG 30-1800 goniospectrometer meets most requirements in evaluation analysis.

GL GONIO PHOTOMETER GLG A 50-1800

It was designed in accordance with the CIE 121-1996 and IESNA LM-75-01 standards, which govern photometric and colorimetric measurement systems in the far field.

Luminance meters

Luminance meters measure one of the most important quantity in lighting design and a key measure in road design and architectural illumination. They enable, in very short time to obtain a complete image showing the distribution of luminance, from which selected points can be analyzed individually.

NEW! GL OPTICAM 4.0 M SC

It provides high-resolution and highly sensitive measurements of parameters related to luminance and color distribution.

GL OPTICAM 1.0

The GL Opticam 1.0 is ideal for all applications where precise and fast luminance measurements are required.

GL OPTICAM 2.0 4K TEC

Imaging luminance meter in laboratory quality with high resolution and thermal stabilization

GL OPTICAM 3.0 4K TEC

The first fully adapted system for measuring street lighting in accordance with the EN 13201: 2016 standard
