Consistent curing requires consistent light intensity, according to Dymax, maker of the new ACCU-CAL 50V radiometer designed to offer repeatable measurement of visible light. The radiometer can measure visible light energy emitted from lightguides (3 mm, 5 mm, and 8 mm), flood systems, and conveyors. With a spectral sensitivity from 395-465 nm (visible portion of the spectrum), a specially designed photo sensor assembly protects the photo sensor from the high temperatures sometimes associated with today’s high-intensity spot lamps. According to the company, there are three reasons to use a radiometer, including maintaining light curing processes so that the system is providing sufficient intensity levels required for successful curing processes; ensure the safety of operators and surrounding workers; and measuring the energy transmission levels of usable curing-energy wavelengths through substrates. This will assure that sufficient energy is reaching the curable resins through substrates that absorb and attenuate needed energy.
