Defence, Aerospace and Astronomy

Precision Apertures are a key element in many defence, areospace and astronomy applications. Graticules use electroforming and laser cutting methods to produce precise, high definition slits and pinholes.

The specification demands for apertures used in space and astronomy telescopes are very demanding. Graticules has perfected processes to provide long apertures with exceptional straightness and parallelism for these applications.

In addition to aperture products, Graticules specialises in manufacturing reticles for sighting systems, with a heritage going back to WW1, and can also offer cemented doublets, multi-layer coatings and small optical assemblies.
