Product Description

ZS-1 ZS-2 KS HS ZHKS Optical quartz glass

Quartz glass has excellent optical spectrum property. It can transmit far UV spectrum , is
the best one of all UV transmitting materials ,and also transmit visible light and near
infrared spectrum. The user can select any sort within the wave-range of 185
mu~3500mu .For its excellent properties ,such as : high temperature proof ,low thermal
expansion ,chemical stability ,thermal stability ,and similar to ordinary optical glass in
bubble , striae ,homogeneity ,birefringence, optical quartz glass became an essential
optical material for high stability optical system under worst conditions .

HS infra-red optical quartz glass. ZS-1 is a kind of synthetic quartz glass made from high pure tetrachloridesilicon.It is characterized for the freedom from the bubbles, highest purity of material, the best transmittance in far UV spectrum,high resistance to radiation . Wave length used: 175 -2500 nm . Because formed by a wet process, the fundamental vibrational band of
incorporated structural hydroxyl ions will absorb strongly at 2730 nm . No grain structure.

ZS-2 is a kind of quartz glass made from synthetic or high pure silica raw material.
Bubble free,no grain structure. It has absorption at 2730 nm. Wave length used:
200-2500 nm.

HS is made from quartz crystal by electric fusion. It is an ideal optical material whose
advantages are almost no (OH), bubbles and striae, good transmission in IR
spectrum .Wave length used : 260-3500nm.

Refraction index and Dispersion of Quartz glass

Ks visible quartz glass is made by H2,O2 fusion crystal ,strongly absorbes at waveband :
200-2500nm and 2600-3800nm.

ZKHS is SiCi4 synthetic quartz glass, made by electric fusion. Its characteritics: no
absorption at 185-3500nm, high purity, bubble free ,no grain structure . ZKHS is the
optimum one in quartz glass.
