Protective Windows

The protective window is processed through fine grinding, grinding, measuring, ultra-high-precision polishing and other processes. Under precise control of the machine tool and processing environment, ultra-high-precision correction polishing technology is used to polish the window surface to achieve an optical plane. Borosilicate windows with shape accuracy ≤ 0.1 micron and surface roughness Ra ≤ 0.01 micron.

Features of Protective Windows

Features of Protective Windows
  • One-stop customized production: Solar Valley processes various round, D-shaped, square, trapezoidal and other structural protective windows according to customer requirements, and can provide windows of different size ranges and materials.

  • Material: borosilicate glass, quartz, sapphire, infrared materials, etc.

  • Protective window properties: strong resistance to mechanical impact and thermal shock, high surface hardness, high transmittance, suitable for use in harsh environments. It can be made very thin and is suitable for visible light use. It is usually used as a protective window for electronic sensors or detectors of the external environment. It is used to separate the environment on both sides to isolate the inside and outside of the instrument from each other, thereby protecting the internal components. Product specification description: 1. Maximum outer dimensions of protective windows: OD ≤ φ300mm, thickness 0.1 ~ 50mm 2. Maximum outer dimensions of protective windows: L×W ≤300×300mm 3. Protective windows can achieve the following accuracy levels according to customer requirements: Ultra-high precision grade: Surface error <0.1μm, surface roughness <0.01μm High precision grade: Surface error <0.5μm, surface roughness <0.05μm Precision grade: Surface error <1μm, surface roughness <0.1μm

  • .Surface defect level: 60-40, 40-20, 20-10, 10-5. Produced according to customer requirements.

  • Coating: Coating according to customer requirements.
