Fused Silica Rectangular Windows

Fused Silica Windows（rectangular）

The fused silica rectangular windows are a part of the protective window or lens. The shape is rectangular, with characteristics such as high transmittance, low refractive index, and low dispersion, which have unique advantages for infrared optical systems and applications in high-temperature environments. The fused silica material has the characteristics of high purity and high temperature melting, which makes the window piece have excellent light transmittance and thermal stability. Fused silica rectangular window slice has a variety of sizes and specifications to meet different application needs. UM OPTICS can provide different types of window sheets such as circular, rectangular, wedge-shaped, perforated, and stepped sheets.
