UV Curved Quartz Dichroic Reflectors

UV cold mirrors reflect UV energy while removing heat-producing visible and infrared energy.  The removal of visible and infrared energy can be accomplished by transmitting the visible and infrared energy through the reflecting optic (typically fused silica) or by absorbing the visible and infrared energy and transferring the absorbed heat to the reflecting optic (typically aluminum). UV cold mirrors are extremely effective at increasing the amount of reflected UV energy at the irradiation zone while simultaneously significantly reducing the visible and infrared energy.  The result is lower temperatures at the irradiation zone, allowing the processing of temperature sensitive substrates.

Cold mirrors are useful in protecting temperature sensitive substrates. Uses include

• Photo polymerization of inks, dyes and adhesives
• Semiconductor manufacture
• Printed circuit board manufacture
• Product packaging
• Flooring
• Water sterilization
• Imaging
