The Proma 140017, UV Exposure Unit 60W is housed in an anodised aluminium enclosure and features a polished crystal plate and electronics integrated in the base with the UV fluorescent bulbs and a timer. The robust lid with foam bed ensures good, even pressure thanks to its toggle-type fasteners. The four aluminium feeder and adjuster bars around the exposure plate allow single and double sided films to be accurately assembled and the alignment of photo coated circuit boards.
