The Single-Side Polished Quartz Plate is a precision optical component with a dimension of 130 x 5 x 1.5mm, featuring optical polishing on one side. The polished surface is scratch-free and clean, providing a reliable optical window for testing and observation applications. Manufactured from high-purity quartz, the plate offers high temperature and acid-alkali resistance with low impurity precipitation, keeping optical performance stable in demanding environments. With precise dimensional tolerance and excellent thermal stability, the plate integrates reliably into optical testing equipment, laboratory optical systems and semiconductor observation assemblies.

• Scratch-free polished surface: The optically polished face provides a clean, defect-free aperture for light transmission.
• High temperature and acid-alkali resistance: The plate withstands elevated temperatures and corrosive cleaning agents.
• High purity with low impurity precipitation: Minimal outgassing keeps processes and samples uncontaminated in service.
• Precise dimensional tolerance: Length, width and thickness are controlled within tight limits for dependable fit.
• Excellent thermal stability: The material resists thermal cycling without deformation or cracking.

The Single-Side Polished Quartz Plate is designed for optical and semiconductor systems that require a clean, stable viewing surface. It is widely used as an optical testing window, allowing light to pass through a polished aperture while protecting the system interior. In laboratory setups, the plate serves as an optical accessory for optical paths, providing a flat reference surface for alignment and measurement. The component is also adopted as a semiconductor observation sight glass, enabling visual inspection of wafers and processes in high-temperature or corrosive environments. Its combination of purity, stability and precise geometry makes it suitable for demanding inspection and testing applications.

• Precise dimensional tolerance: Accurate size control ensures reliable mounting and alignment in equipment.
• Customizable unpolished side: Frosting or sandblasting can be applied on the unpolished face to meet application needs.
• Excellent thermal stability: Stable geometry and optical performance are maintained across temperature changes.
