Opsytec Dr. Groebel GmbH

Opsytec Dr. Groebel GmbH is one of the world's leading suppliers of industrial UV measurement technology. We are developing, producing, and distributing UV measuring instruments, UV sensors, UV equipment, and UV irradiation chambers for a wide range of industrial applications.

For this purpose we are accredited in accordance with DIN EN 17025:2005 as a calibration laboratory  for UV sensors and as a test laboratory for spectrometers, spectroradiometers and light sources.

Since 1981, we have established industry milestones with our products again and again. For example, as early as 1986 we were able to offer a microprocessor-controlled stand-alone spectral radiometer called SR-02. It was followed by many compact and durable UV radiometers, and the product range was expanded consistently. In 1991, we received DIN CERTO certification as an facility for non-therapeutic UV radiation equipment.

In 2016 we moved into our new location "Am Hardtwald 6-8,76275 Ettlingen". With a significantly increased production and laboratory area, we are thus underlining our future orientation.

Since 2017 we are the first calibration laboratory accredited by the German DAkkS that calibrates broadband radiometers to irradiance.

Quality and punctuality are of utmost importance to us. Therefore, we rely on efficient quality management and enhance this by our ISO 9001:2008 certification. read more

Opsytec Dr. Gröbel has an accredited calibration laboratory for the irradiance and a test laboratory for lamps and spectroradiometers. This labs are certified according ISO 17025.

UVpad - spectral UV radiometer for belt dryers

The UVpad is a powerful, accurate, and easy-to-use spectral radiometer.
Without optical filters, it's especially designed to measure different UV lamps and UV LEDs - also available with external sensor head.

UV-LED large area flood lamp

High UV irradiance combined with a uniform irradiated area is the key feature of the series L. The LED modules are air-cooled high-power UV LED sources emitting at 365, 385, 395, 405 or 450 nm.
