Drilled Optical Window
Drilled windows are optical elements with hole structures machined into optical windows, allowing precise control of hole position, diameter, depth and other parameters. The aperture area allows the beam to pass through unobstructed, while the non-aperture area maintains the transmission or reflection characteristics of the window and provides physical space for other elements in the optical path; the hole shape is usually circular, and square and other shapes can also be customized.

Diameter: 10 mm to 127 mm Diameter Tolerance: +/-0.02mm Material: JGS1
The Brewster window uses the material's total-reflection properties. At the specified incidence angle, known as the material's Brewster angle, the S-polarized component is partially reflected while the P component is nearly fully transmitted. Sunday offers various UV fused-silica Brewster windows for ultraviolet applications.

An optical dome is a lens element with two concentric spherical surfaces. Common materials include K9 glass, fused silica, ZnS and ZnSe, with parallelism tolerance controlled within 2μm. Typical shapes are hemispherical or hyperhemispherical. Widely used in detectors, optical sensors, underwater photography and security monitoring, domes protect internal optics, provide a wide-angle light-entry window and optimize optical transmission.
