Precision Optical Aperture (OSS Series)

【Product Overview】

The OSS Series precision optical apertures are made from SS-304 stainless steel in ø9.5mm (3/8") standard discs with 0.013mm thickness. Inspected, selected and evaluated for high-quality imaging and diffraction applications, they offer higher circularity (>1µm) than standard apertures with minimized substrate thickness.

【Key Features】

(1) Precision optical grade, circularity > 1µm, better than standard apertures;

(2) Minimized substrate thickness to reduce ringing of the diffraction pattern;

(3) Sharper diffraction patterns than standard apertures;

(4) SS-304, hole sizes from 1 to 1000µm;

(5) Individually packaged in clear plastic case with label for identification.

【Typical Applications】

Spatial filtering, molecular beam masks, pinhole cameras, high-precision imaging, diffraction and optical measurement.
