•Temperature coefficient corrected •Low profile - disk shape design •Optimized for precise UV curing measurements and profiling utilizing its internal data memory •Robust design for use in high temperature environments under intense UV radiation typically found in UV curing applications •Selectable calibration entries stored for different UV LED & blue LED wavelengths for reduced measurement uncertainty •Cosine corrected field-of-view UV curing is a process in which photocurable chemicals applied to substrates are irradiated with high energy UV LED, traditional UV arc or blue light sources. This energy accelerates polymerization (cross-linking) and consequently the hardening or drying (curing) process. The irradiating energy must be controlled and monitored since too low a dose will not cure the product, whereas too high a dose may damage the surface layer. In this industry conveyor belt systems are commonly employed with the product traveling at a set speed through the UV curing station(s). The belt speed is determined to ensure the required UV dose is delivered. One downside to this system is that irradiance intensity profiles are produced due to LED, UV or blue light source spacing along the belt. Low profile UV radiometers that can travel down the production line under or through UV curing stations are an important quality control tool. They provide real time measurement of UV curing irradiance and dose ensuring fully cured product repeatedly. One critical design element of the UV disc meter is its ability to withstand high temperatures and intense UV radiation while maintaining stability between recalibrations.
