About GL Optic

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.

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 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.
