Chrome-on-Glass Optical Aperture OFI1-20
JCOPTIX chrome-on-glass apertures use UV fused silica with chromium and precision-etched central holes. The fundamental mode passes while chromium blocks stray light. Rear broadband AR coatings provide high aperture transmission for spatial filtering and shaping. Hole size, shape, and outside diameter are customizable. Applicable models: OFI05-3, OFI05-5, OFI05-10, OFI05-20, OFI05-S100, OFI05-S200, OFI05-S500, OFI05-S1000, OFI1-3, OFI1-5, OFI1-10, OFI1-20, OFI1-S100, OFI1-S200, OFI1-S500, and OFI1-S1000. Chromium OD_abs>4; operating band 400-1100 nm; circular or square holes; outside diameters 12.7 mm or 25.4 mm. JCOPTIX apertures have diameters 12.7 mm or 25.4 mm and thickness 1.5 mm. Circular holes are 3, 5, 10, or 20 μm; square holes are 100, 200, 500, or 1000 μm. OD_abs>4 chromium and rear broadband AR over 400-1100 nm block stray light for filtering and shaping. Customization is available through technical support.

ID-12 Aperture U-optic
Length: 23 mm Outer-ring diameter D: 19.5 mm Adjustable diameter: Φ1.5-Φ12
The ID adjustable aperture continuously varies the central opening in spatial filtering, allowing selected frequency components in the spectrum plane to pass while blocking others, thereby changing the image's frequency content in the image plane. It consists of multiple curved blades. Its carefully engineered structure and precision assembly provide moderate damping between the blades, avoiding both stiffness and looseness.
