Opticam GL Optic

Who are we?

We manufacture, distribute and support professional light measurement systems.

From single LEDs to comprehensive luminaire testing, We provide integrated light measurement solutions across a broad array of industries and applications:
  • Lighting Manufacturers,
  • Electronic Companies,
  • Automotive Component Providers,
  • Laboratories and Scientific Applications


Our business was born of necessity. In the early 2000’s Jan Lalek, a leading physicist and developer of optical products, was looking for a way to simplify the light measurement. Michael Gall of Just Normlicht, a leading manufacturer of standardized viewing solutions, had a need for high performance, affordable measuring equipment to support rapid development of new lighting systems.
The ensuing partnership created GL Optic as a start-up in 2009, and formed as a separate business unit in 2014.
In the picture (from L to R), there are Jan Lalek, the co-founder and head of technology, Michael Gall, the entrepreneur and co-founder.


Today, GL Optic’s headquarters in Poland designs, develops, manufactures and supports a broad range of light measurement instruments and turn-key systems for a wide range of applications and industries.
Our team includes experienced software developers, electronic and mechanical engineers, production technicians, sales and support engineers, all focused on delivering high performance, cost-effective solutions.
Our customers include leading multi-national manufacturers of lighting systems, test laboratories, and integrators, as well as start-ups and consultants worldwide in every industry concerned with light measurement.


We are expanding our business and services further. GL Calibration Laboratory is in the process of installing primary optical radiation reference standard – the Black Body Radiator. This is the first venture of such a standard in the Central and Eastern Europe. We establish a world-class metrological accuracy for the benefit of our customers. Our software and hardware are in a constant updating process to meet the requirements of international standards and provide the latest metrics.
