Radiometer validates UV curing process for consistency

Where both validating and monitoring of the UV lamp output is vital to consistent production quality, Intertronics has produced the Dymax Accu-Cal 160 radiometer.

It is designed to be used with both benchtop flood curing lamps and conveyor systems, and is available in two versions, for either broad spectrum or LED-based UV curing lamps.

The radiometer will help process and quality engineers understand the curing energy of their lamps, and to ensure that their emissions are maintained within the required parameters. This is vital to full and consistent curing of light curing materials such as adhesives, coatings, potting compounds and inks.

The Accu-Cal 160 simplifies cure process validation, and is recommended for checking curing lamps where bulbs will need replacing due to normal degradation.  Suitable for outputs up to 10W/cm², it can be used to determine intensity (measured in mW/cm²) or total energy or dose as derived from intensity and exposure time (measured in mJ/cm²). It features an extended calibration cycle of 12 month intervals.

The radiometer may also be used to measure the light transmission rates of various wavelengths through substrates that absorb UV and/or visible light. To assure an effective curing process it is critical to measure the light intensity reaching the bondline below the intervening substrate. In this way, it ensures consistent production quality, says the company.

The radiometer and can be controlled manually via four buttons on the faceplate or by a USB remote interface. Measurement results are displayed on the integrated LCD or transmitted by the USB remote interface to a computer.
