Knight Optical offer a range scientific optical components including custom aperures. Both our standard grade laser drilled and electroformed precision custom pinhole apertures are supplied in a range of pinhole diameters making them ideally suited to a range of laser applications where beam shaping is required or saturation of a detector needs to be limited.

Pinhole apertures are also used to determine a systems field of view and to limit the effect of aberrations. Whilst our standard range of pinhole apertures are widely used in general applications helping to limit saturation of detectors and the effects of aberrations, our high precision and high powered pinhole apertures offer increase performance and radiation dissipation for laser applications.

Custom pinhole apertures are available as unmounted foils or ridged mounts for seamless integration into your application. We are also able to supply in a range of alternative materials such as customised ceramic apertures with customized mounting options

Knight Optical supply high quality custom pinholes made to your exact custom specification. Every component is individually tested by our highly skilled technicians in our state of art metology lab
using our Starrett AV300 non contact dimensional imaging devise to ensure all components meet our high quality standards.
