Optical Crystal Glass Sapphire Wafer Price
Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm
Synthetic
Sapphire
is
a
single
crystal
form
of
corundum,
Al2O3,
also
known
as
alpha-alumina,
alumina,
and
single
crystal
Al2O3.
Sapphire
is
aluminium
oxide
in
the
purest
form
with
no
porosity
or
grain
boundaries,
making
it
theoretically
dense.
The
combination
of
favourable
chemical,
electrical,
mechanical,
optical,
surface,
thermal,
and
durability
properties
make
sapphire
a
preferred
material
for
high
performance
system
and
component
designs.
For
various
semiconductor
applications,
sapphire
is
the
best
choice
in
comparison
with
other
synthetic
single-crystals.

Sapphire
is
used
in
analytical
applications
where
combinations
of
high
temperature,
pressure,
and
hydrofluoric
acid
species
are
encountered.
These
applications
need
the
survivability
of
sapphire,
while
often
needing
other
properties
such
as
favourable
UV
(ultraviolet)
or
IR
(infrared)
transmission.

tubes;
Sapphire
is
used
for
very
high-pressure
applications
in
replacement
of
glass
or
quartz
tubes.
·
Sample
preparation
-
sapphire
is
used
in
digestion
cells
as
sheaths
and
liners.
When
hydrofluoric
acid
is
used,
sapphire
replaces
quartz
components
·
Analytical
chemistry
-
for
mass
spectroscopy,
ICAP,
and
other
systems,
sapphire
replaces
quartware
to
improve
durability
and
reduce
contamination
while
offering
good
UV
transmission.
Medical
applications:
·
Sapphire
is
used
in
surgical
systems
for
laser
transmission
and
in
contact
with
bodily
fluids.
·
Surgical
tips
-
sapphire
is
used
in
contact
tips
for
various
surgical
laser
applications
·
Endoscope
lenses
-
sapphire
is
often
used
in
endoscope
lenses
due
to
its
durability
in
contact
with
tissues
and
in
sterilisation
environments
such
as
autoclaving
·
Sapphire
knives
-
with
a
sapphire
knife,
thinner
sections
are
possible.
The
near
perfect
cutting
edge
of
this
knife
/
blade
gives
distortion-free
sections
down
to
10
microns
thick.
Optical
applications:
·
Sapphire
is
used
for
short
and
long
wavelength
applications
(UV
and
IR)
beyond
the
range
where
conventional
optics
performs
adequately.
High
temperatures
and
hostile
environments
also
necessitate
the
use
of
sapphire
optics.
·
Illumination
windows
-
for
very
high
brightness
illumination,
sapphire
windows
survive
the
very
high
heat
while
providing
the
broadest
spectral
transmission.
