Light Meters, Detectors, UV-VIS-NIR Radiometers
Devices and systems for photometric, radiometric and colorimetric measurements of light and optical radiation. Light Meters and Radiometers for different applications like UV radiation, Laser measurements, LED measurements, photomedicine and much more.
We offer one of the most comprehensive photometer (light meter) and radiometer product ranges including light measurement detectors in the industry. Coupled with our versatile and high class optometers (respectively current amplifiers and display units) we are able to support you for your measurement requirements. Whether the radiometers or light meters task is: laser pulse measurement, low signal illuminance detection, photomedicine, UVC disinfection, radiation curing, PAR, infrared detection, etc. We usually have a suitable light meter solution ready!
In the following categories you will find exemplary application solutions and combinations of our products to ready to use radiometers or light meters. If you do not find what you are looking for, please contact us for individual radiometer respectively light meter advice. We are happy to support you! Especially because of the multitude of possibilities for radiometers or light meters and the different optical characteristics of the detectors with different focus (highest sensitivity, most optimal cosine response, different calibration strategies, etc.) a consultation can lead to the optimal radiometer and light meter solution.
Due to the modular detector concept, partly with stored calibration data in the detector head for plug & play application, it is also possible to equip one Optometer/Display Meter with different detectors to enable several applications with one radiometer at a reasonable price.
At the same time, we do not compromise on precision. Our measurement systems allow highest radiometric measurement accuracy by very low dark currents, automatic offset corrections and more than 30 years of experience in the analog amplifier field. Especially these are very challenging due to the measurement of a few pA (picoampere). Our experience also shows in the optimally adapted detectors (responsivity curves), cos responses, linearity as well as calibration strategies and provided rel. spectral responsivities of the detectors for further corrections.
A detector head comprises one or more photodiodes each with an appropriate optical bandpass filter, diffuser, lens assembly, integrating sphere or other optical elements. Detector heads are calibrated in the Gigahertz Optik GmbH's calibration laboratory.
Optometers, Amplifiers, Display Meters
Optometers are a specific type of digital multimeter (DMM) used for optical radiation measurements. The particular light detector(s) connected determine the wavelength range/spectral weighting function and displayed measurement units.
