Product Description

General Introduction: VAD Fused silica CFS-100
Due to the great innovation and improvement of traditional VAD (vapor phase axial deposition) method in optical fiber fabrication technology, Raytek / c-laser has successfully developed the latest synthetic fused silica material cfs-100. The purity of Raytek/C-laser CFS-100 is very high, and its OH content is lower than that of traditional process, Raytek/C-laser CFS-100 is a kind of high-quality synthetic fused silica which can be widely used in semiconductor and liquid crystal display industry. In terms of optical properties, Raytek/C-laser CFS-100 adopts advanced manufacturing technology and process. Therefore, in addition to heat resistance, mechanical strength and chemical resistance, it also has high ultraviolet transmittance, high purity and excellent weather resistance.

Main Characteristics:
Raytek/C-laser Synthetic fused-silica offer a number of advantages over glass or fused quartz:
1).Greater ultraviolet and infrared transmission
2).Low coefficient of thermal expansion, which provides stability and resistance to thermal shock over large temperature excursions
3).Wider thermal operating range
4).Increased hardness and resistance to scratching
5).Much higher resistance to radiation darkening from ultraviolet, X-rays, gamma rays, and neutrons.
6).Optical-quality synthetic fused silica (OQSFS)
7).Low Hydroxyl content
8).High transmittance
9).Low cost.
