RCH-109
Detector head for high intensity irradiation in blue-peak light curing processes
Separate light integrator and detector with rigid fiber coupling
In UV curing applications requiring deep curing of adhesives and paints, longer-wave radiation in the blue spectral range is used to excite the photoinitiators. UV radiometers for these applications must be designed in such a way that they only measure the irradiance in the actinic range of the photoinitiators. See our application note about general UV curing measurements and our product overview about UV curing meters.
Product description RCH-109 irradiance detector
The UV detector RCH-109 was specially developed for use in UV curing with discharge lamps. It offers all the features and functions of the detectors of the RCH series (see RCH-xxx Series). Its spectral responsivity covers the wavelength range from 390 nm to 460 nm, which is used in particular for deep curing of adhesives and paints.
Calibration
The detectors are calibrated with regard to their responsivity to irradiance and are supplied with a factory calibration certificate that corresponds to the high standard of the measuring laboratory for optical radiation measurements of Gigahertz-Optik. If necessary, a test certificate accredited according to DIN EN ISO / IEC 17025 can optionally be created for the detector with the associated measuring device.
