HPFS® fused silica glasses are known throughout the industry for their consistent and repeatable performance. Many different grades of fused silica can support various product applications. Glass codes 7979 and 7980 are high purity non-crystalline silica glasses with excellent optical qualities. Product characteristics include extraordinarily low refractive index variations leading to state-of-the-art homogeneity values, low birefringence values, large size capabilities, exceptional transmittance from the deep ultraviolet through the infrared region, and an ultra-low thermal expansion coefficient; all of which are critical to our customers' demanding needs.

HPFS® 7980 Standard Grade meets high T≥ 88.00 %/cm @185 nm. (Equivalent to T. ≥> 80.00 %/cm @185 nm)
HPFS® 7980 KrF Grade meets high T. ≥ 99.90 %/cm @248 nm.
HPFS° 7980 ArF Grade meets high T, ≥ 99.50 %/cm @193 nm.
Higher transmittance is available upon request.

In the optical component, Quartz glass can be mainly divided into three grades:
JGS, JGS2, and JGS3 according to the spectral application range:
JGS1 Synthetic Fused Silica: 185nm-2500nm
JGS2 Fused Quartz: 220nm-2500nm
JGS3 Infrared Optical Quartz: 260nm-3500nm

Besides domestic materials, we also offer materials in all grades and specifications from major manufacturers such as Corning, SCHOTT and Heraeus. The materials have high purity and uniformity, ensuring finished products have better and more stable performance.
Depending on the customer's custom needs, considering the optical, mechanical and chemical properties of the material, we recommend more suitable materials or other specified materials for processing
