Detectors for High Irradiance Light Sources High power irradiances light sources are in use for several applications Solar Simulators High speed Imaging Environmental Simulation UV Curing Irradiance and Irradiance Dose Quantification As a light source ages its light output changes so in a critical process the source irradiance and energy needs to be quantified to ensure a constant incident irradiation over the entire lamp operating time. Selection of Spectral Ranges from 250 nm to 400 nm The effective radiation in a UV process typically falls within a narrow wavelength range within the lamp’s total emission spectrum. Therefore optical bandpass filters are used to limit the detector‘s sensitivity to that narrow spectral range of interest. UV-Energy and Heat Resistant Detector Design High energy UV radiation places special demands on the radiometers used to measure these high power sources. Conventional UV irradiance detectors exhibit drift and instability over time and use. Gigahertz-Optik has developed a detector design based on an integrating element called RADIN that is able to withstand these high temperatures and high UV radiation. The RADIN element is exposed to the UV signal while the active detector is capsulized outside of the irradiated zone and coupled to the RADIN input optic by fiber light guide. RCH-0xx Series Detectors with Flexible Light Guide The RCH-0 detectors are equipped with a 50 cm / 20 inch long flexible light guide between the RADIN element and the photodiode/filter capsule. The flexible light guide allows the sensor element to be placed remotely.
