75μm Aperture Diameter, 25mm Mounted, Acktar Blackened Pinhole

Product Details Low Reflectance from the EUV to SWIR 99% Absorbance Blackening Coating Aperture Sizes from 20 to 1000μm Available Unmounted and Mounted Acktar Blackened Pinholes feature Acktar Magic Black blackening coating that provides wide-band low reflectance from the extreme ultraviolet (EUV) to the short-wave infrared (SWIR). This coating provides near zero outgassing and can be used in temperatures up to 380°C. Acktar Blackened Pinholes are coated on both sides, including the pinhole edge, and are available either unmounted or mounted in a 25mm mount for easy integration into optical systems. These stainless steel substrate pinholes are ideal for spatial filtering applications requiring low back reflection and scattering from light sources.
