Bern Optics has made available coated optical apertures with outside dimensions as small as 0.20mm in diameter. The aperture can be circular or made to custom shapes and held to micron tolerances.
Created from optical and filter glasses, these microscopic elements – some as small as a grain of salt – can be produced with apertures positioned within microns of a physical feature. Custom designed anti-reflection coatings can be applied to all transmitting surfaces. Bern Optics can also provide apertures cemented to other optical components in a sub-assembly. These extremely precise elements are ideal for use in any application where a precision aperture is required.
