Quart Glass JGS 1 - Ultra High Purity Synthetic

JGS1 quartz glass, a type of synthetic quartz, is produced using SiCl4 as raw material and melted with a high-purity hydrogen-oxygen flame.  

• High Hydroxyl Content: Contains a significant amount of hydroxyl groups (approximately 2000 ppm).
• Excellent UV Transmission: Exhibits superior UV transmission properties, especially in the short-wave UV region.
• Transmittance at 185nm can reach 90% or higher.        
• Absorption Peak: Displays a strong absorption peak at 2730 nm.  
• Structure: Lacks a grain structure, unlike some other types of quartz glass.

JGS1 is used for optics operating in deep UV and the visible wavelength range,

Some of the applications include

• Laser
• Lenses
• Windows
• Prisms
• Mirrors, etc.).

The following equivalencies exist for Synthetic Quartz Silica (specifically JGS1):

• Heraeus: Suprasil 1 and 2  
• Saint-Gobain: Spectrosil A and B
• Corning: Corning 7980
• Dynasil: Dynasil 1100 and 4100  

It is important to understand that these are considered equivalent materials, meaning they share similar properties, particularly regarding their high purity and excellent UV transmission.
