UV Light Measurement
Nov 2011Dymax Corp.Request Info
Dymax Corp. has released the Accu-Cal 150, a radiometer offering repeatable, NIST-traceable measurement of UV light for validating and monitoring a light-curing process. The instrument can measure UV light up to 10 W/cm2 emitted from stationary light-curing floodlamps or lamps used in conveyor processes. It can be used to determine intensity (measured in mW/cm2) or total energy as derived from intensity and exposure time (measured in mJ/cm2). The device also can be used to measure the light transmission rates of various wavelengths through substrates that absorb UV and/or visible light. Spectral sensitivity is 320 to 390 nm, and typical accuracy is ±5%. Using radiometers in UV light-curing application processes ensures that any changes to the properties of curing energy are identified.
