Sapphire windows description:

Sapphire has a wide transmission range, spanning the three wavelength bands of ultraviolet, visible light and infrared and has high thermal shock resistance, high hardness and wear resistance. Almost no substance except the diamond can produce scratches on its surface, and its chemical properties are stable which is insoluble in most acid solutions. Furthermore, because of its high strength, windows made of sapphire are thinner.

Sapphire Windows Applications

Optical Systems:
Sapphire windows are widely used in optical systems for their high transparency across the UV, visible, and IR spectrum, making them ideal for cameras, sensors, and laser systems.
Aerospace and Defense:
Their durability and resistance to high temperatures and pressure make them suitable for missile domes, cockpit windows, and protective optics.
Medical and Scientific Instruments:
Sapphire windows are employed in spectroscopes, endoscopes, and other diagnostic equipment due to their scratch resistance and chemical inertness.
Industrial Applications:
Commonly used in harsh environments such as high-pressure chambers, vacuum environments, and process monitoring equipment.
Electronics:
Utilized in devices requiring robust protection, such as smartphone screens and watch crystals.

Package of Sapphire Windows

For sensitive applications, sapphire windows are vacuum-sealed to prevent contamination or moisture exposure.

Different Types of Sapphire Windows

Round Sapphire Windows

Sapphire has better light transmittance in the wavelength range of 0.20 - 5.50 μm and the infrared transmittance hardly changes with temperature.

Square & Rectangular Sapphire Windows

Square and rectangle sapphire windows are widely used in many fields, such as high-temperature infrared windows, bar code scanning windows and various optical components.

Custom Sapphire Windows

Due to the extensive applications of sapphire in various fields, different dimensions are required. Stanford Advanced Materials can provide custom sapphire windows of any size and thickness in complete orientations.

FAQs

Q1 What are the benefits of using Sapphire Windows?
Sapphire windows offer exceptional optical clarity, high thermal and mechanical resistance, scratch resistance, and chemical inertness, making them ideal for demanding applications.

Q2 Do you provide anti-reflective (AR) coatings for Sapphire Windows?
Yes, AR coatings can be applied to improve transmission and reduce reflections. Specify your wavelength requirements for customized coatings.

Q3 Are Sapphire Windows transparent in the infrared spectrum?
Yes, sapphire windows are highly transparent in the UV, visible, and IR spectrum, with excellent transmission from 150 nm to 5 µm.
