Knight Optical (UK) Limited products

Our high precision eyepiece graticules, also referred to as reticules, are manufactured by photolithographically printing a pattern onto a thin glass substrate. Eyepiece graticules are typically used in gun sights, scopes and other ranging systems for civilian and military use. Graticules are also used in handheld measurement tools such as loupes and magnifiers. Each pattern is designed to fit the appliction and generally consists of a mix of circles, lines and linear dimensions.
