UV exposure units, or UV exposure lights, are devices that give out UV (Ultra Violet) light at concentrated levels. UV exposure units are used with photo sensitive material to create PCBs (printed circuit boards). They are also used for hot foil polymer plates and making signs. They are ideal for treating larger pieces of work in one go.
UV exposure unit cases are usually made from aluminium for additional strength whilst . The feature multiple UV bulbs for great UV coverage. Double sided exposure units have UV light hit the object from both sides. The lid of a exposure unit may contain a pressure pad to help keep the artwork and photo sensitive material together.
The exposure unit usually features a base and a lid. UV bulbs can sit within the base of the unit, within the lid, or both. Once the exposure unit is closed encased UV lamps, which lay underneath clear glass or plastic, emit rays of UV light which is typically a purple light. This UV light then makes with a desired surface, usually used for drying, curing or treating.
