Product Description
General Introduction:
Synthetic Fused Silica, the epitome of high purity and noncrystalline silica glass, brings forth an unparalleled fusion of a remarkably low thermal expansion coefficient with extraordinary optical properties and supreme transmittance. Its key features include impressive homogeneity, minimal birefringence, and exceptional transmittance across a broad spectrum, from deep ultraviolet (DUV), UV, visible light, to infrared regions.
Our HPFS Fused Silica glasses are celebrated industry-wide for their consistent and reliable performance. We present a variety of fused silica grades to meet diverse application needs. Glass code 7978 exemplifies high purity non-crystalline silica with superior optical qualities. It boasts exceptionally low refractive index variations, translating into top-tier homogeneity, minimal birefringence, the capability to support large sizes, and unparalleled transmittance from the deep ultraviolet to infrared, complemented by an ultra-low thermal expansion coefficient, all critical to fulfilling the sophisticated demands of our customers.
Products Name: Explore our diverse range of grades: Synthetic Fused Silica 0F Grade, 0C Grade, 0A Grade, along with krf and Arf Grades, each tailored to deliver precise solutions for your optical needs.
