UV Radiometers- Ultraviolet Measurement Systems

Posted on: May 12th, 2020

Avantes UV Radiometer systemUV Radiometers provide the quantitative measurement of light sources emitting electromagnetic radiation in the wavelengths from 100-400 nm.  The ultraviolet wavelength range can be subdivided into three distinct spectral bands, A, B and C.  The ultraviolet A covers the range from 315-400 nm, the ultraviolet B range from 280-315 nm and the Ultraviolet C from 100-280 nm.   There are a variety of applications which require ultraviolet radiometry ranging from solar measurements to ultra-violet disinfection in water treatment or medical disinfection.

UV Radiometers from Avantes offer a variety of compact, affordable ultra-violet radiometer systems with detection ranges from 180-400 nm, with purged options for vacuum measurements.  The systems consist of Avantes AvaSpec spectrometers, a fiber optic and a collection optical head such as a cosine corrector or integrating sphere.  The entire system is radiometrically calibrated using a NIST traceable source our in house calibration lab.  We also offer ISO 17025 certified calibrations for customers requiring this.   Avantes ultra-violet radiometers facilitate in situ measurements and through control enabled by Avantes AvaSoft software, can be set to measure over designated time intervals without direct operator intervention.
