High Irradiance LED Sources for UV Curing
High power UV and BLUE LED sources are appearing in several applications including UV and BLUE light curing.
Measurement of LEDs from 365 nm to 430 nm
The RCH-116 detector head is specially designed for high power LED light sources in the wavelength range from 365 nm to 440 nm. It offers a relatively flat (radiometric) spectral responsivity to minimize measurement uncertainty if any shift in LED wavelength occurs.
Calibration at Six Wavelengths
The detector is calibrated at typical LED wavelengths 365 nm, 375 nm, 385 nm, 395 nm, 405 nm and 430 nm at Gigahertz-Optik’s calibration laboratory. Certificates describe the calibration procedure and traceability.
RCH-116 Detector with Rigid Light Guide
The RCH-116 detectors are supplied with a 22 cm / 8.7 inch long rigid light guide between the RADIN element and the photodiode/filter capsule.
Traceable Calibrations
Calibration of irradiance in W/cm² and W/m² is performed at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
Optical radiation is spectrally defined as covering from UV-C to far infrared. In UV Curing applications only the high energy radiation in the UV-C to BLUE range is initialization the polymerization. UV Curing detectors should only detect UV within the specified wavelength range of the irradiation source.
Conventional UV detectors are built with a diffuser, UV bandpass filter and photodiode which are directly irradiated by the high intensity ultraviolet and heat radiation which can reduce life time and cause damage and temperature drift.
Gigahertz-Optik’s RCH series UV detectors are built with a low profile housing and UV and temperature stable Radiation Integrator. The photodiode and UV bandpass filters are located outside the critical hot zone coupled to the RADIN diffuser by a flexible or rigid light guide.
