PLE/PLF series light source uses special structure and special light-emitting method. It can freely choose different light-emitting surface dimensions. PLE series light source can be thinnest at 11.7mm, which can meet the requirements of different narrow space requirements. PLFseries is the largest light-emitting surface. Can achieve 1000 * 1000mm, can meet the large volume detection objects, and the high uniformity can be widely used.
