These filters transmit only the UV radiation needed for UV curing. Use of a UV filter minimizes heat generation on the illuminated surface making it ideal for use with parts and materials, which are vulnerable to heat.
The following two filters are available according to the wavelength range to be blocked.
-- 03 type: Transmits UV radiation very efficiently but blocks (absorbs) visible light.
-- 05 type: Uses two filters to block visible to infrared light, achieving better absorption of heat rays than –03 type.
Both types have a long service lift. Almost no drop in the transmittance even, after 10,000 hrs of operation.
