Sapphire Assembly Component

Sapphire crystal - the hardest oxide crystal, is the most fundamental single crystal form of aluminium oxide (al2o3). It has valuable physical properties such as high strength, high melting point, chemical properties and a variety of optical properties.

1.Main uses:

Sapphire crystals have a wide range of uses. Because of its high hardness, good wear resistance, good transparency and high heat resistance, sapphire is often used to make sapphire watch crystals, sapphire blades, chisels, gemstone bearings, etc. Sapphire is now used to make the outer glass of many high-end watches. Sapphire is often used to make various optical components, optical Windows, missile fairings, etc., because of its good light transmittance in the 0.20-5.50m band, its infrared transmittance hardly changes with temperature, and its wear resistance, heat resistance, and high hardness. In addition, sapphire substrates play an extremely important role in the semiconductor lighting industry of leds.

2. Three major categories of applications for sapphire:

1) Sapphire watch crystals, surgical knives, gemstone bearings:

2) Sapphire optical components:

3) Sapphire substrate for leds.

Sapphire prisms

Shanghai Xiwei Optoelectronic Technology Co., Ltd. offers a variety of high-precision prisms, such as right-angle prisms. Conical prisms, pentagonal prisms, duff prisms, ridge prisms, withering prisms or other irregularly shaped prisms. Many types of prisms each have a specific geometry to achieve the necessary reflection to perform a particular imaging task. Reflective prisms can be inverted, rotated, deflected, or replaced with light. Dispersing prism spectral separation spectral adjustment production laser output.

Sapphire substrate

Sapphire substrates are the preferred substrates for the current blue, violet, white light-emitting diode (LED) and blue laser (LD) industries (where gallium nitride films need to be epitaxial on the sapphire substrate first) and are also important superconducting thin film substrates. In addition to being able to produce Y- series. In addition to high-temperature superconducting films such as La- series, it can also be used to grow new practical MgB2(magnesium diboride) superconducting films.

Sapphire window

Sapphire window sheets are ideal materials for high pressure, high vacuum, or high corrosive environments and are widely used in electro-optics, aerospace, biopharmaceuticals.

Sapphire lens

Sapphire lenses are made from optical-grade grown sapphire. Sapphire is chemically produced to be corrosion-resistant.

Sapphire rods

Sapphire crystal rods are widely used in various laser applications in surgical operations. For instance, sapphire crystal rods are used in 2940nmEr:YAG. Sapphire axles are used for coronary stents and so on.

Sapphire light blocks 

Light blocks and filters are the focus of the optical components on pulsed light machines, which filter ultraviolet light and retain useful wavelengths of 400nm to 1200nm for cosmetic lasers such as hair removal, vascular and acne treatments. Available wavelength of 400 nm / 420 nm / 460 nm / 490 nm / 515 nm / 530 nm / 550 nm / 560 nm / 570/590 nm / 615 nm / 645 nm / 695 nm / 755 nm / 780 nm / 810 nm.

UItraopto Precision Optics Co. Ltd. provides light guide blocks and filters that polish all surfaces using advanced polishing machines. The surface quality of its input and output surfaces can reach 20/10, effective flatness λ/10.

The sapphire window sheet transmits wavelengths ranging from 0.17 μm (deep ultraviolet) to 5.5 μm (mid-infrared), and is one of the few optical materials that can take into account the ultraviolet, visible, and infrared bands simultaneously. It is extremely hard, with a Mohs hardness of 9, second only to diamond (Mohs hardness of 10), and much higher than fused silica and calcium fluoride. It can withstand the friction and impact of gravel and metal particles without causing scratches and is suitable for harsh working conditions; It is difficult to process, requires diamond grinding wheels for cutting and polishing, and costs more than ordinary optical glass. It has a bending strength of about 400 to 500 MPa and excellent thermal shock resistance. Resistant to acid and alkali corrosion, no reaction to strong acids, strong bases, organic solvents except hydrofluoric acid (HF) and hot phosphoric acid, superior to fused quartz. Suitable for observation Windows in chemical and semiconductor wet etching processes; It can be used for a long time in harsh conditions such as dampness and salt spray without aging or discoloration. Radiation-resistant performance, insensitive to ultraviolet light, X-rays, gamma rays, no color center, suitable for aerospace ultraviolet remote sensing, nuclear industry inspection and other scenarios. High melting point and heat resistance, with a melting point of up to 2045 ° C, it can work for a long time below 1000 ° C and withstand short-term temperatures up to 1500 ° C, far exceeding fused quartz (melting point 1710 ° C). Low coefficient of thermal expansion, good thermal stability, little deformation when temperature changes, ensuring the stability of optical parameters.
