Opsytec Dr. Gröbel GmbH: UV measurement since 1981

Opsytec Dr. Gröbel GmbH develops, manufactures and calibrates optical measurement and irradiation systems for ultraviolet and visible radiation. The programme ranges from a single UV sensor through radiometers and spectroradiometers to complete irradiation systems. The programme comprises UV sensors, radiometers, spectroradiometers, UV LED systems, irradiation chambers and customer-specific optical solutions for industry and research. The company goes back to Dr. Gröbel UV-Elektronik, founded in 1981; manufacturing takes place in-house at its site in Ettlingen near Karlsruhe, Germany.

We are accredited as a calibration laboratory for UV sensors and as a testing laboratory for spectrometers, spectral radiometers, and light sources in accordance with DIN EN ISO/IEC 17025:2018-03. The quality management system is certified to DIN EN ISO 9001:2015.

Milestones

1981 – Dr. Gröbel UV-Elektronik is founded; the first UV measuring instruments are built.

1986 – The SR-02 spectroradiometer brings a microprocessor-controlled stand-alone spectrometer to market.

1991 – DIN CERTCO certification as a testing body for non-therapeutic UV irradiation equipment.

2008 – Dr. Stefan Pieke and Dr. Mark Paravia found Opsytec GmbH for development services and contract measurements in optical technologies.

2013 – Opsytec GmbH and Dr. Gröbel UV-Elektronik merge; Dr. Manfred Gröbel had led the latter for over 30 years. The range now spans application, development and measurement.

2016 – Move to Am Hardtwald 6–8 in Ettlingen, with substantially larger production and laboratory space.

2017 – Accreditation as an ISO 17025 calibration laboratory for calibrating broadband radiometers for irradiance (registration number K-20284-01-00).
