Precision Apertures

High Precision Electroformed-foil and chrome on glass pinholes and slits. 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 more complex and smaller patterns.

Why Electroforming?

A major part of our business is manufacturing custom apertures for products like spectrometers, collimators, MTF testing, augmented reality, space telescopes and numerous other optical devices. Please send us your requirements.
