sub1micron - Sub 1 Micron Apertures

Call For Price

We are pleased to introduce a new line of sub micron apertures. Manufacture of apertures less than 1 micron in diameter is made possible by the development of composite apertures consisting of a molybdenum (Mo) support with a thin sheet of platinum (Pt) foil fused to the surface. The sturdy Mo support contains a visible counterbore to simplify locating the very small aperture hole.

Please call us for details.
