Rectangle Sapphire Glass window Optical Sapphire Window Plate Customized Products
Description
The rectangular sapphire window is a double-plane rectangular
optical sapphire glass, which is usually used as a protective
window for sensors and detectors. The window does not change the
magnification of the system.
Hechen Crystal provides window coating services, anti-reflection
coatings, high-reflection coatings, spectroscopic coatings, metal
coatings and other optical coatings. Broadband antireflection
coatings can be used in the ultraviolet, visible, near-infrared and
mid-infrared bands.

As a transparent physical barrier, windows enable light to enter a
different environment from one environment. For example, from air
to water, or from vacuum to air. Such as different temperature,
pressure, chemical composition or cleanness.
The hardness of sapphire is only lower to diamond and it is hard to
scratch. Its transmission wavelength ranges from deep ultraviolet
to infrared. At present, sapphire is a kind of material widely
used, which has the properties of scratch resistance, impact
resistance and flexibility. Sapphire has long been used to make
watch protective glass or camera lens protective glass cover and
filter glass, and now it is widely used to make mobile phone
screen. Sapphire glass is composed of colorless synthetic corundum
(a mineral produced by alumina AL2O3). In fact, strictly speaking,
sapphire is not a kind of glass, because it does not have glass
amorphous structure, but a crystal structure.
Sapphire window products can be used as Gan, GaAs and other new
materials, integrated circuit substrates, epitaxial and directional
substrates, watch glass lens, optical lenses and surface acoustic
wave devices; Because sapphire has good light transmittance, its
infrared transmittance almost does not change with temperature, so
it can be used as infrared window, high temperature furnace
observation window, counter window, etc. It ranges from ellipse,
oblique disc, step window, oblique disc and so on.
Sapphire (Al2O3) glass optical window is a high-performance optical
window and substrate material. It has a high transmittance in the
ultraviolet/visible light/infrared band, the transmission range is
170nm-5.5um, and it is resistant to high temperatures (under
1700℃). Long-term service), high hardness, second only to diamond,
and resistance to acid and alkali corrosion.
Sapphire glass can be used as optical window lenses, lens
protection lenses, windows, armored windows, wear-resistant
windows/optical components, high-temperature and impact-resistant
optical windows, etc.
Silian Optoelectronics provides sapphire substrates and window
materials with excellent performance, and can process different
sizes and shapes according to your requirements to ensure excellent
optical performance.
The sapphire optical window plate is a kind of plane plate, which
has two parallel or wedge-shaped faces. It is usually used as the
protective window of electronic sensor or external environment
detector. The window slice does not change the magnification of the
system. The substrate materials include sapphire, optical glass,
K9, ultraviolet fused silica, infrared fused silica and crystal
materials such as CaF2, MgF2, ZnSe, GE and Si. Various optical
coatings such as antireflective coating, high reflection coating,
spectroscopic coating and metal coating are also provided. Wide
band antireflection coatings can be used in ultraviolet, visible,
near infrared and mid infrared bands.
Sapphire optical window is a plane polished product based on single
crystal sapphire processing. Sapphire protection window is a
special window plate used to protect the observer, the inside of
instrument and the inside of container by using the pressure
resistance, wear resistance and high temperature resistance of
sapphire.
Single crystal sapphire window chips are very suitable for
demanding applications such as laser systems because of their high
surface hardness, high thermal conductivity, high dielectric
constant and resistance to chemical acids and bases. Because the
hardness of sapphire is second only to diamond, and its structural
strength is very high, the thickness of sapphire window sheet made
by enhanced transmittance is thinner than that of ordinary high
dielectric window sheet. In terms of chemistry, sapphire is a
single crystal aluminum oxide (Al2O3), which is very suitable for
0.2 to 5.5 μM. In general optical applications, the basic
requirements of customers can be met without coating. Our products
can also be coated, screen printed or special heat treated
according to customers' requirements to meet customers' special
needs.
It has ultra-high surface hardness and chemical resistance.
The wavelength from UV to mid infrared can be transmitted.
It is thinner and stronger than the standard glass window.
Product shape can be divided into: round, rectangular, step shape
and a variety of Machinable shape.
Product size range: diameter (maximum diagonal) 10-500MM, thickness
0.3-100mm.
Finish after polishing: 80 / 50, 60 / 40, 40 / 20, 20 / 10, 10 / 5
(American Standard).
