Sapphire Glass Window

Tcoptics, one of professional big size sapphire windows manufacturers, provides
all types of custom sapphire windows, which have a series of excellent physical
and chemical characteristics such as high strength, high hardness, high-
temperature resistance, abrasion resistance, corrosion resistance, good light
transmission performance and excellent electrical insulation performance.
Therefore, the sapphire window can be widely used in various demanding fields
such as national defense, scientific research, and civil industry.

Sapphire windows are known as being high performers in any industry for their
overall versatility and ability to withstand abrasive applications that would
otherwise break glass made of silica. Sapphire optical window is hard, strong,
and wears resistant. Because of sapphire hard properties, so it can be used in
Aerospace windows, downhole and drilling vision systems, inspection windows,
watch crystals, and gun sights. Sapphire window transparency is very good also.
So it is ideal for deep sea and underwater sensors.

Our team of experienced engineers and technicians use advanced manufacturing
techniques and equipment to ensure that our optical windows are of the highest
quality, with exceptional clarity, low levels of birefringence, and minimal
wavefront distortion. This makes them ideal for use in many optical
applications, including imaging, spectroscopy, and laser optics.

Sapphire Optical Window Feature
Ideal for high temperature, high pressure, or strong vacuum environments.

Highly corrosion resistant.

Transparent from 170 nm to 5.5 µm.

Extremely hard and more durable than standard optical glass.

Sapphire Window Cleaning
Cleaning a sapphire custom optical window is similar to cleaning any other type
of window, but you need to be careful to avoid scratching the surface. Here are
some steps you can follow to clean a sapphire window:

Prepare the cleaning solution: Mix warm water with a small amount of mild soap
or detergent in a container.

Wet a soft cloth with the cleaning solution: Make sure the cloth is clean and
free of any debris that could scratch the surface.

Gently wipe the sapphire window: Use the wet cloth to wipe the surface of the
window, being careful not to apply too much pressure.

Rinse the window: Use a separate clean cloth or sponge to rinse the window with
clean water.

Dry the window: Use a clean, soft cloth to dry the sapphire window. Avoid using
paper towels or any other abrasive materials that could scratch the surface.

If the window has stubborn stains or grime, you can use a specialized sapphire
cleaning solution, which can be purchased from jewelry stores or online
retailers. Be sure to follow the manufacturer's instructions carefully when
using these products.

Sapphire window transmission
Sapphire windows have excellent optical properties, including high transmission
in the visible to near-infrared (NIR) wavelength range. The exact transmission
characteristics of a sapphire window depend on factors such as its thickness
and surface quality, as well as the wavelength of the light passing through it.

In general, sapphire windows have high transmission in the visible spectrum,
with transmission rates of up to 90% or more depending on the thickness of the
window. In the NIR range, sapphire windows also have high transmission rates,
typically over 80% for wavelengths up to 2 microns.

However, as the wavelength increases beyond 2 microns, sapphire windows become
increasingly opaque due to absorption. At wavelengths around 3 microns,
sapphire windows have a transmission rate of around 50%, and at 4 microns, the
transmission rate drops to around 10%. Therefore, if you need to transmit light
at longer wavelengths, you may need to consider other materials such as
germanium or zinc selenide, which have higher transmission rates in the mid-
and far-infrared regions.

Sapphire Glass Window Uses
Sapphire windows can be used in vision systems, inspection windows, watch
crystals, and gun sights. Underwater security equipment. Sapphire windows can
be widely used in gas and oil analysis, barcode readers, and IR analysis
devices. Its application in industry, military, defense, space, medical and
research sectors. Sapphire optical windows can be made a great deal thinner
than other optical windows, which results in improved transmission. Sapphire
optical windows are useful through a wide wavelength range of 0.15 to 5.5µm and
are resistant to UV radiation darkening.
