Pyser Optics 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 straightness/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.
