Precision Pinholes 10PP are round aperture precisely formed and controlled in a kovar foil. To facilitate handling, a pinhole foil is mounted in a Ø25 mm black metal donut. The Precision Pinholes 10PP can be used in our Precision Spatial Filters 10SF130 and YZ Positioner for Lens, Pinholes and Objectives 5ZYP-1. We also offer pinholes with diameter D in the range of 45-100 µm every 5 µm. Precision Pinholes of custom diameters up-to 200 µm are available on request. These pinholes of different sizes could be used for producing gaussian beams.
