Our quality slits are laser-drilled into 302 stainless steel substrates with thinning at the aperture for increased sharpness and definition. Slits, like other apertures, offer control of beam shape and size to help limit saturation of detectors and minimise abberations. Slits offer fixed beam control and are ideal for applications requiring high repeatability and accuracy.

High-powered slit apertures are used for higher intensity applications, primarily in laser systems, where the high levels of irradiation incident on the aperture are dissipated more quickly by the substrate.

Our high-powered apertures are copper substrates with gold plating on one side for reflecting radiation, with the other side flat ploy black coated for absorption.

Typically our high powered slit apertures can withstand 100-200MW/cm2 at 10ns pulses (700nm) and are thinned to 25µm around the aperture for increased definition of shape and sharper edges.

Knight Optical also offers an extensive custom optic service thanks to our many years of experience in the industry. Our apertures can be manufactured to any size or shape to suit your application. More information is available by contacting
