In the world of the very small, National Aperture, Inc. has led the industry in innovations in Precision Apertures for thirty years.

If you need round apertures, these are the roundest. If you need straightness, these are the straightest. If you need clean edges, these are the cleanest. If you need production quantities of Apertures, NAI compete with them all with five combined fabrication technologies.

NAI specialises in Aperture sizes from 0.5 μm to 1000 μm and up.

Apertures (micro-precision pinholes, slits, etc.)are made in a variety of materials including high-damage metals and exotic foils. And NAI do things no one else can do, including making pinholes on optically reflective surfaces.

You will find these pinholes used in SPATIAL FILTERS, LASER GAS/LIQUID FLOW, HIGH POWER LASER LIGHT CONTROL, MICROSCOPE CALIBRATORS, ASTRONOMICAL TELESCOPES, AEROSPACE, and more.

If you need custom apertures, or production runs, Laser Support Services is confident that these precision apertures can satisfy your most demanding requirements.
