We offer an extensive range of detectors to measure radiation from UV to IR. Radiometers to measure solar radiation with weather proof housing as well as filter based radiometers with individual spectral response.

UV Radiometer for solar UV radiation measurement

We offer the UV-A, UV-B, UV-E, UV-AB and UV-A/UV-E Broadband Detectors for measuring precise global UV irradiance for different spectral ranges. The systems provide a considerably improved measurement accuracy in comparison to the traditional detectors. The direct cosine error f2 is typically less than 1.5%.
The detectors are flexible enough to be easily installed on every measurement site. Detector base plates for individual alignment work and a shadowring system J1033-Shadowring (pdf 42k) make an effective meteorological system.

Filter Based Detectors

We also offer a range of filter based detectors offering “close match” spectral responses to the desired function. For example, the DH400-VL photometric detector provides high accuracy illuminance and luminance measurements.
Some of the most common detector types are listed below:
ModelSpectral FunctionWavelength rangeNormal calibration
DH400-XYZx,y,z Colorimetric380-780nm(x,y), K, lux
DH400-UVA-xRadiometric UV-A315-400nmW/m²

DH400-R01-xRadiometric ‘blue’400-500nmW/m
DH400-R02-xRadiometric ‘red’700-800nmW/m²
DH400-R03-xRadiometric ‘visible’400-800nmW/m²
DH400-R04-xRadiometric ‘near IR’800-1000nmW/m²
DH400-R05-xRadiometric ‘vis-NIR’400-1000nmW/m²

The ORM400 Optical Radiation Meter is ideally suited to display the measurements from the DH400 range of detectors as well as third party current generating detectors. The ORM400 has a USB 2.0 interface and is supplied with powerful calibration features and data display functions. It includes a library of standard spectral light sources to which customers may add. This accommodates greatest accuracy and flexibility when measuring light sources with a filter based instrument.
