Standard power pinholes are made of 302 stainless steel; and high power pinholes are made from copper with gold plating on one side and flat poly black coating on the other and are intended for use with high continuous power (i.e. Argon and Krypton) lasers and high pulse power lasers. Precision slits with similar specifications are also available.



Custom laser cut patterns of all sorts can be made in thin metal film from a variety of materials.
