    Pinholes and Slits

    Pinholes and Slits are used to provide a fixed or adjustable aperture through which laser beams may be directed in a number of laser applications such as spatial filtering. Pinholes and Slits consist of variously shaped apertures within a range of materials or coatings designed to reflect or absorb laser light that does not pass through the opening. A selection of mounts is also available for holding aperture slides.
