| specifications︰ | ZS-1 is a kind of synthetic quartz glass made from high pure tetrachloride silicon．It is characterized for the freedom from bubbles， highest purlty of material， the best transmittance in far UV spectrum， high resistance to radiation． Wave length used：175-2500nm． Because formed by awetprocess，the fundamental vibrational band of incorporated structural hydroxyl ions Will absorb strongly at 2730nm．No grain structure．
ZS2 is a kind Of quartz glass made from synthetis Or high pure silica raw material． Bubble free， no grain structure． It has absorption at 2730nm． Wave length used：2002500nm．
HS is made from quartz crystal by electric fusion， It is an ideal opticai material whose advantages are almost no (0H)，bubbles and striae，good transmission in IR spetrum．Wave length used：260-3500nm．
|
| Advantages︰ | Quartz glass has excellent optical spectrum property．It can transmit far UV spectrum，is the best one of all UV transmiting materials， and also transmit Visible light and near infrared spectrum．The user can select any sort Within the waverange of 185mµ- 3500mµ．For its excellent properties，such as：high temperature proof，low thermal expansion，chemical stability，thermal stability，and Similar to ordinary opticai glass
in bubble，striae，homogeneity，birefringence，optical quartz glass became an essential optical material for high stability optical system under worst conditions．
Among the above mentioned products，the HS infra-red opticai quartz glass was awarded the China National Silver medalfor its excellent quality |
