Handheld Radiometer Measures UV and Blue Light

This radiometer can maintain stability in high temperature and intense UV flood and spot curing environments.

Gigahertz-Optik presents its handheld X1-1-RCH-116-4 UV and blue light LED curing radiometer featuring a horizontally constructed photodetector assembly that keeps the photodetector out of the hot zone. The radiometer is also able to maintain stability in high temperature and intense UV flood and spot curing environments.

The remote-controlled, four-channel X1-1 meter features auto-ranging from 0.1 pA to 200 uA or manual range selection, CW, dose, run/stop, offset and peak hold functions, selectable integration time from 20 milliseconds to 1 second, USB interface, backlit LCD and is compatible with all Gigahertz-Optik single and multi-sensor (up to 4) light detector heads.

The RCH-116-4 wand-style detector consists of a RADIN radiation integrator coupled to a stainless steel rigid tube housing a quartz light guide that pipes the light signal to a detector capsule housing the photosensor/filter assembly. RADIN provides a cosine-corrected spatial response along with a light guide and remote detector capsule that provides signal attenuation and thermal isolation. The detector assembly is not subject to direct irradiation, which reduces ageing and saturation effects and allows the RCH detector to operate in temperatures up to 1000 C° (peaks up to 2000 C°).

The detector covers the spectral range from 350-465 nm with calibration points at key LED wavelengths and can measure irradiance levels up to 40,000 mW/cm2. The low-profile RCH detector enables measurement 8 mm above the exposure plane. Optional S-X1 software is available.
