What is Optical Windows Feature

1. Suitable for high power,high-pressure applications and vacuum or corrosive atmospheres.
2. Sapphire is a single crystal form of alumina.The material is extremely hard and resistant to attack by srong acid.
3. It has high compressive strength, a high melting point and excellent thermal conductivity.
4. Low distortion,low scatter and excellent parallelism for laser and non-laser applications.

Specification

Spherical sapphire bearings are suitable for supporting movable parts such as electrical measuring instruments, thermal measuring instruments, navigation and aviation instruments, and water meters.

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.
