Features of Borosilicate Windows

Features of Borosilicate Windows
  • One-stop customized production: Solar Valley processes various circular, D-shaped, square, trapezoidal and other structural borosilicate windows according to customer requirements, and can provide different size ranges and materials. Window piece, the base material is borosilicate glass

  • Material: borosilicate glass, such as TEMPAX, PYREX, Borofloat33, etc.

  • Properties of borosilicate glass windows: 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 borosilicate glass windows: OD ≤ φ300mm, thickness 0.1 ~ 50mm 2. Maximum outer dimensions of borosilicate glass windows: L × W ≤ 300 × 300mm 3. Borosilicate Glass windows can reach the following precision levels according to customer requirements: Ultra-high precision grade: surface shape error <0.1μm, surface roughness <0.01μm High precision grade: surface shape error <0.5μm, surface roughness <0.05μm Precision grade: surface Form error <1μm, surface roughness <0.1μm

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

  • Coating: Coating according to customer requirements.
