>>> Sapphire Windows
Sapphire
window is made from synthetic sapphire. Due
to the hardest of the oxide crystals, Sapphire has a
combination of optical and physical properties that makes it
the best choice for a variety of demanding applications.
Sapphire maintains its strength even at high temperatures. It
has good thermal properties, excellent electrical and
dielectric properties and is resistant to chemical attack.
These properties encourage the use of Sapphire in aggressive
environments where reliability, optical transmission or
strength is required.
Sapphire
window can be made much
thinner than BK7 windows.
It has
a wide transmission range. Sapphire
window is best suited for scratch resistance application that
requires better transmission over a broad transmission spectrum.
New
Rise Optics can supply a variety of sapphire optics range from
round windows, rectangular windows to rods. We are
capable of supplying sapphire window with diameter up to 3 inches.
