Innovations in Optical Measurement Technology Made in Germany

Light Measurement Technology Directly from the Manufacturer

Gigahertz Optik GmbH provides more than thirty years of experience in the development, production, calibration and distribution of optical radiation measurement equipment. We are globally recognized experts in the entire optical spectral range from ultraviolet (UV) to infrared (IR).

As a medium-sized manufacturer, we offer a high level of flexibility and respond to the needs of our customers and markets. We always try to help our customers in being successful. Our company has earned worldwide recognition through the individual and intensive support of our customers in many areas of research and industry. We are also part of the Berghof Group, which offers us very good framework conditions and allows long-term planning

Innovative Technology for Challenging Applications

With a wide range of products from detectors, spectroradiometers, homogeneous light sources to entire measurement systems paired with a large selection of accessory components such as calibration standards, we can fulfill just about any application in optical radiation metrology. We also specialize in custom solutions which further broadens our scope.

Our fields of application are diverse including but not limited to measurement solutions for UV radiation, SSL characterization, measurement of general and special lighting, assessment of optical radiation risk, measurement of solar radiation and photomedicine, characterization of image sensors or the optical determination of material properties.


Quality and Know-How

In addition the continual development of new and existing products, we at Gigahertz Optik GmbH, have always paid special attention to the quality aspect of our products and services. We are particularly proud to present our calibration laboratory for optical radiation measurements. Its ISO/IEC 17025 accreditation for spectral sensitivity and spectral irradiance (German Accreditation Body DAkkS D-K-15047-01-00) offers the highest and most rigorous industry standard for the traceability of our calibrations
