Optical Glass Windows |
| |
Optical glass windows, plates
and discs are fabricated in a broad range of optical glasses
having many applications and uses for scientific, medical,
optical and industrial companies.
Optical glass windows are used for the visible spectrum
allowing visible transmission
transmitting visible light through the window. This is
not their only purpose as they have a wide range of refractive
indexes andoptical properties. They act as a protection
window protecting sensitive and fragile equipment. The
refractive index of optical glass which ranges from 1.42nd
to 1.85nd are used for test pieces and monitor windows
in thin film coatings.
Optical glass materials are made by major glass manufacturers
from around the world including Schott Glass, Pilkington
Special Glass and Ohara Optical Glass.
Optical Glass manufacturers produce a large inventory
of optical glass which includes doped glass, high index
glass, crown glass, sealing glass, flint glass, radiation
resistance glass and non browning optical glass, which
are all used in optical window manufacturing.
Polished optical glass windows are made to standard and
precision finishes in a wide size and product range. |
