GL SPECTROMETERS
Reliable equipment instrument for measuring optical radiation parameters
Spectrometer - the indispensable tool for measuring optical radiation
Spectrometers are used to determine spectral characteristics and measure the parameters of light. These instruments measure basic quantities such as light intensity (illuminance), luminous flux and color temperature, as well as help prepare detailed spectral analysis.
Dedicated optical probes make it possible to test all kinds of sources under various conditions and extend the range of instrument capabilities. GL’s proprietary SPECTROSOFT M software is used to accurately analyze the results obtained.
Spectrometers are essential equipment in the quality control and R&D departments of lighting, display and LED manufacturers.
Complete data at hand
GL Optic’s portable spectrometers enable measurements to be taken anywhere, anytime. Thanks to their battery-powered operation, the spectrometers can be successfully used during lighting audits. The touch screen display on the GL SPECTIS 1.0 Touch provides an overview of the results without the need for a computer.
Measure what cannot be seen
Selected instruments offer advanced measurements in the extended spectral range from 200 nm to 1050 nm (UV-VIS-NIR). High-quality optical components and multi-stage factory calibration guarantee precision and repeatable measurements.
Stay informed
We are constantly striving to improve our instruments so that they operate in line with current requirements. Among other things, GL Optic’s spectrometers enable light ripple (flicker) measurements to be made in relation to the requirements of Ecodesign EU 2019/2020.
Spectrometers that guarantee repeatability and precision
GL Optic’s spectrometers are instruments of relatively simple design. However, the use of high-quality components from renowned optoelectronics manufacturers such as Hamamatsu combined with the extensive knowledge and experience of our engineers, guarantee excellent accuracy and repeatability of measurements.
The temperature sensors installed in the spectrometers monitor temperature changes and automatically compensate for all changes in dark current levels, ensuring excellent measurement stability.
Thanks to the built-in touch screens on GL SPECTIS 1.0 Touch and GL SPECTIS 5.0 Touch, it is possible to read out the measured values directly and to view spectral distributions or ripple characteristics (in the Flicker version) instrument.
More analytical functions are offered by the optional GL SPECTROSOFT M software.
Spectrometers for laboratory applications
Thanks to their versatile concept and design, GL Optic spectrometers are a great addition as a measuring instrument for working in conjunction with an integrating sphere as well as a goniometer.
The spectrometers are ideal for LED measurements in the laboratory in accordance with the requirements of CIE 127:2007, CIE 025/E:2015 and IESNA LM-79-08.

One spectrometer, multiple measurement options
The intelligent automatic detection of the measurement probes connected to spectrometers greatly expands the spectrum of possibilities of GL Optic instruments. All it takes is one spectrometer with a set of dedicated optical probes and light intensity, luminous flux and luminance measurements are possible.
The small integrating sphere GL OPTI SPHERE 48 included with GL SPECTIS 1.0 Touch + Flicker is an excellent tool for measuring the luminous flux of single LEDs, while GL OPTI PROBE 1.0.10 is suitable for luminance measurements of displays and monitors.
GL SPECTROLUX
Reliable, precise and simple to use spectral distribution meter
GL SPECTROLUX, a spectral distribution meter, provides a complete set of accurate optical data at a low price. Reliable light measurement is no longer the domain of experts or external laboratories. The individually calibrated GL Optic instruments guarantee fast access to precise results.
Data analysis and ready-to-use results reports
The free Spectrosoft Connect software allows basic measurement analysis and the creation of reports that summarize relevant results. Wider analysis is available with the industry-leading GL SPECTROSOFT M software. The software offers completely customized reporting options, extended parameter calculation capabilities and unique tools such as lighting audit automation and a spectrum mixer.
GL SPECTIS 1.0
Compact and versatile
Despite its compact size, the GL SPECTIS 1.0 portable spectrometer allows any light source to be examined. Depending on your needs, the meter allows you to: measure illuminance – when connected to a computer, measure luminous flux and light color – when connected to an integrating sphere, and to measure luminance using dedicated GL OPTI PROBE optical probes.
Excellent precision
The components used in the instrument guarantee the highest quality measurements. The spectrometer’s optical system uses a miniature collimating lens with a nano-printed diffraction grating and a CMOS sensor operating in the 340-780 nm range. It is a low stray light system that produces measurement data in 1.7 nm increments, making it an ideal tool for measuring LED sources.
GL SPECTIS 1.0 Touch
Immediate insight into results
GL SPECTIS 1.0 Touch has been designed based on the experience built on a simpler screenless model , the GL SPECTIS 1.0. The aim was to create a spectrometer with good optical performance, powered by a battery, with the immediate ability of on-screen viewing of results. Advanced design, technology and calibration make the instrument suitable for a variety of applications from field testing to laboratory control.
Automatic optical probe detection
The spectrometer comes standard a Class B angle-corrected probe as the primary probe for measuring illuminance. The unique automatic detection mechanism of the attached optical head eliminates the possibility of measurement errors resulting from changing probes.
Factory calibration of the spectrometer meets the requirements of standardization institutes and is certified by the manufacturer.
GL SPECTIS 1.0 Touch + Flicker
Up to date with the latest standards
The new version of the popular spectrometer has been expanded to include the ability to measure light ripple, in addition to the already wide range of standard photometric and colorimetric values. The meter has been equipped with an additional electronic module and a high-speed photodiode to measure the frequency and quality factors of the flicker. These enhancements allow measurements such as SVM and California Title 24.
Response to Ecodesign requirements
According to the EU Ecodesign regulation, manufacturers and importers of LED sources are required, among other things, to measure the Pst LM parameter, i.e. the flicker index. This measurement is possible using the GL SPECTIS 1.0 Touch + Flicker spectrometer together with the dedicated GL SPECTROSOFT M software in the PRO or LAB version.
GL SPECTIS 4.0 M

GL SPECTIS 4.0 M spectroradiometer allows measurements over a wide wavelength range from 200 to 1050 nm in accordance with many standards, including those for photobiological safety (EN 62471) or measurement of LED products (IESNA LM-79-08). The instrument is optimized for demanding tests and measurements of UV and IR radiators.
Laboratory-grade repeatability
High-quality optical components, multi-stage traceable factory calibration, a stray light reduction system and automatic temperature compensation help to obtain precise and reproducible results, making the GL SPECTIS 4.0 M an excellent instrument for use in a professional laboratory.
GL SPECTIS 5.0 Touch
Highest precision in a portable form
GL SPECTIS 5.0 Touch optical spectrometer is the new benchmark for quality for a variety of applications among portable light measuring instruments. Until now, such photometric and radiometric accuracy was only available in much more expensive stationary measuring instruments. GL SPECTIS 5.0 Touch is not only suitable for applications in the laboratory, but also for measurements in the field, thanks to its compact size and built-in touch screen.
