Our apertures are supplied in a range of forms and grades and offer precise control of beam shape and size with sharp edges.
Both our standard grade laser-drilled and precision apertures are supplied in a range of pinhole diameters and slit widths and lengths, making them ideally suited to a range of laser applications where beam shaping is required or saturation of a detector needs to be limited. Apertures are also used to determine a system’s field of view and to limit the effect of aberrations.
Whilst our standard range of apertures are widely used in general applications, our high precision and high powered aperture offer increase performance and radiation dissipation for laser applications.
Knight Optical’s Iris diaphragms offer circular aperture variation for the direct control of throughput in systems. We supply oxide coated sprung steel and stainless steel iris diaphragms in both fully and partial closing types.
