Sight Glass, Pressure and High Temperature Resistant Glass Window

Items: trapezoidal frames/360 window glass/combined glass/framed mirrors/conical mirror windows.

Specifications: Ф12*1 Material: Optical glass （K9)

Windows/protective glass for optical instruments, with AR antireflection coating on request.

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.

Diameter: 1 mm to 1000 mm Diameter Tolerance: +/-0.02 mm Material: Bk7 Sapphire Fused silica 、ZnS2、CaF2、Si、Ge。

Sunday-optics specializes in precision optical windows, using four-axis polishers, large annular polishers and two-axis machines to manufacture high-precision windows for customers.

Material: H-K9L、JGS1、 Sapphire Available diameter: 8-400 mm Diameter Tolerance [or Customer design]: +0.00/-0.05mm or Customer design

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.
