In UV curing applications for surface and deep curing, radiation in the UV and visible spectral range is used to excite the photoinitiators. UV radiometers for applications in which LED technology is used for irradiation must be designed in such a way that the irradiance is measured within the spectral range emitted by the LED.


Product description
RCH-013 irradiance detector

The RCH-013 UV detector was specially developed for use in UV curing with UV LEDs. They offer all the features and functions of the RCH series detectors (link to RCH-xxx series data sheet). Their spectral responsivity covers the wide wavelength range from 240 to 550 nm and thus applications for surface and deep curing.


Calibration

The detectors are calibrated in 5 nm steps with regard to their spectral irradiance responsivity 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.
