aperture plates

vast variety of aperture solutions with customized micro structures

aperture plates

Precision aperture plates with micro pinhole, slits and other micro patterns are essential parts in many products across industries. Typical application can be found in Gamma-ray detectors, spatial filters, spectroscopes, endoscopes, leak detectors, high power laser light control, pinhole cameras, TEM specimen grids, etc

With the Electroforming technology, Veco offers vast categories of precision aperture products, ranging from standard aperture plates with pinholes/slits, to high power apertures, laminated multi-layer electroform apertures, and customized microstructures for any complex geometries and specific application environments. Integrated in house techniques of precision electroforming, etching, plating, and laser cutting further enable us to provide vast variety of aperture solutions with flexible choices of materials, thickness, layers, finishing, etc.
