UV Heat Filters


Proprietary UV Heat Filters are designed to significantly reduce process heat in UV curing systems. Coursen Heat Filters work by reflecting very specific wavelengths of light emitted by both the plasma and the envelopes of typical mercury vapor long arc lamps. Designed for high power industrial applications, they offer long life and reliable performance.
