GL Spectrometers Spectis range


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.

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 spectral distribution meter


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 5.0 Touch Laboratory Specrometer Spectroradiometer


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.
