UV Measurement: Why and How

UV measurement is an essential and integral part of a UV curing application process.

A UV measuring device called a Radiometer provides the ultimate in process control allowing for measurement of the radiant energy output of the light guide or optical accessory generally directly at the cure site, either at specified wavelengths or integrated over broad wavelengths. The radiometer is an essential tool to set, monitor and control the exact amount of output irradiance for maintaining a repeatable, calibrated process traceable to the National Institute of Standards and Technology (NIST). A quality Radiometer should retain it's calibration for at least 6 months. A memory for storing data with a PC software interface for downloading makes it easy to track and log the processes.

Measuring devices can be combined with Spot Curing systems to provide a complete curing station with unmatched control and repeatability. Special electronics built into some sophisticated radiometers allow for connection of custom sensors for measuring light energy directly at the cure site, with some detector systems accurately measuring wide varieties of spot cures. Light guide ports automatically sense a diverse range of industry standard light guides (2, 3, 5, 8mm diameter).
