Apertures - Slits & Pinholes


Pyser-SGI produce apertures and slits in both metal foil and on glass substrates to very high resolution. The metal foil products are all made using electroforming techniques to give excellent edge definition and stratightness/roundness, features essential in many optical applications to provide precise beam definition without light scatter. The glass products are created using vacuum deposited chrome and photomasks, this allows complex and smaller patterns than may be possible in electroforming.

The brochure (click below) gives all of the metal foil and glass pinholes and slits but many customers require something more specific for their applications, in this case Pyser has a very cost effective custom-make facility to provide quantities from single pieces to many thousands.
