Optical slit/pinhole 1 - 300 µm | R039xx-00 series

Pinholes are used in holography to remove unwanted spatial intensity variations in a laser beam. Thus, the intensity side bands from a Gaussian beam are stripped away. These pinholes are un-mounted and are available from 1 to 1000 microns. Gold coating can be applied to the pinhole surface to allow it to operate in high energy environment. Custom sizes are available upon request.
