Etch and Fill Reticles

Etch and fill reticles, also known as day/night reticles are a specialty of Graticules Optics Limited. The skills and equipment required to make them are an important part of the complex production process, and very few companies have these capabilities. These reticles are predominantly used in night vision and periscope sights but have uses in numerous applications where a coloured image is required against a background where a normal black image would not be clearly visible. By side illuminating the reticle the etched and filled pattern will appear white against a dark background

Graticules Optics has been producing etch and fill reticles for over 60 years and can also offer cemented doublets and small optical assemblies.
