1. optical transmission . Good optical transmission makes it have more luminous flux than
quartz at the same power (watt). So it is brighter.
2.thermal expansion coefficient . Its thermal expansion coefficient is much closed to that of
molybdenum. So it works perfectly without the help of the molybdenum belt.
3. lamp protecting. For schott glass can filter out UV radiation, auto lamp can be protected
to a certain extent.
Disadvantage: it can not meet with cold water when it is working, or, it will blast.
