    Cold filters are designed to protect the more sensitive substrate from direct infra-red radiation. They also protect the UV lamps and reflector assembly from dust and other contaminants, particularly when the lamphead is inverted. The cold filter is manufactured from material that is naturally transparent to UV, but reflective to infrared radiation.
