New DYMAX ACCU-CAL 50V Visible Radiometer For Use With Visible Light Curing Systems

Consistent curing requires consistent light intensity. The new ACCU-CAL 50V radiometer from DYMAX is simple to operate and offers repeatable measurement of visible light. The ACCU-CAL 50V 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 to 465 nm (visible portion of the spectrum), the ACCU-CAL 50V measures intensities from 1 mW/cm2 to 40 W/cm2. A specially designed photo sensor assembly protects the photo sensor from the high temperatures sometimes associated with today's high-intensity spot lamps.

There are three reasons to use a radiometer:

• Maintaining Light Curing Processes – A radiometer measures whether a light curing system is providing sufficient intensity levels required for successful curing processes. Radiometers provide the same monitoring control for light curing processes that a thermometer would provide for measuring temperature in thermal-curing processes.
• Providing Worker-Friendly Light Curing Processes – The ACCU-CAL 50V is sufficiently sensitive to measure the intensity of stray or reflected visible light (as little as 1 mW/cm2) to ensure the safety of operators and surrounding workers.
• Measuring Transmission Rates Through Substrates – A radiometer can be used to measure 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.
