Ultraviolet Radiometer for Light-Curing Process

Transcript:
A radiometer is an important tool in a light during process because it measures the intensity and/or energy associated with light of specified wavelengths. Since UV light is not visible to the human eye, a radiometer is required to determine the amount of UV energy being emitted from a curing source.
Using a radiometer to measure light intensity is beneficial for three reasons. Maintaining a reliable light curing process, providing a worker-friendly light curing environment, and measuring transmission rates through substrates.
Benefit number one, maintain a reliable light-curing process. UV curing bulbs, light guides, and reflectors can deteriorate over time, causing less UV energy to reach the cure surface, resulting in incomplete cures. A radiometer can measure whether a light curing system is providing intensity above the minimum or bulb change intensity. Adjusting the process by using a radiometer to measure intensity can keep the process consistent and ensure the quality of finished products.
Benefit number two: provide a worker-friendly light curing environment. A radiometer can be used to determine if any stray UV light is reaching operators or bystanders, helping to ensure a safer, more worker-friendly light-curing process.
Benefit number three: measure transmission rates through substrates. A radiometer can be used to measure the transmission rates of various wavelengths through substrates that sometimes absorb various frequencies of energy. To ensure an effective curing process, it is important to measure the light intensity reaching the cure site below any intervening substrate.
