Sapphire Crystal Products and Custom Precision Parts

We provide sapphire crystal materials and finished sapphire components for customers in the semiconductor, optical, electronics, scientific instrument and industrial equipment sectors.

Our product range covers sapphire crystal blanks, wafers, circular windows, rectangular plates, rods, tubes and special-shaped components. Products can be supplied in raw, ground, lapped or optically polished condition according to the required application.

Sapphire is synthetic single-crystal aluminum oxide rather than conventional glass. It offers a valuable combination of high hardness, optical transparency, electrical insulation, wear resistance and thermal stability.

From initial material selection to precision machining and inspection, sapphire components can be manufactured according to customer drawings, samples and technical specifications.

Why Sapphire Is Used in Demanding Applications

High Surface Hardness

Sapphire provides excellent resistance to scratching and abrasion. It is often selected for windows and protective covers exposed to dust, particles, repeated cleaning or mechanical contact.

Оптическая прозрачность

Optically polished sapphire can transmit ultraviolet, visible and infrared light across a broad wavelength range.

Transmission performance is affected by:

• Material thickness
• Crystal orientation
• Surface quality
• Surface roughness
• Operating wavelength
• Optical coating
• Environmental conditions

Термическая стабильность

Sapphire maintains useful mechanical and insulating properties at elevated temperatures. It is suitable for high-temperature observation systems, sensors, furnaces and process equipment.

Химическая стойкость

Sapphire resists many corrosive substances and harsh operating environments, making it suitable for chemical processing, semiconductor equipment and industrial instrumentation.

Electrical Insulation

Sapphire is an electrically insulating material and can be used as a substrate or structural component in electronic and high-voltage applications.

Механическая прочность

Compared with conventional optical glass, sapphire offers improved resistance to pressure, impact and wear when properly designed and installed.

Типовые применения

Custom Processing Services

We support multiple sapphire manufacturing and finishing processes.

Manufacturing feasibility depends on minimum wall thickness, hole size, spacing, tolerance and component geometry.

Surface Finish Options

Ground Surface

A ground surface is suitable for structural, positioning or non-optical applications where transparency is not required.

Lapped Surface

Lapping can improve flatness, parallelism and dimensional control before final polishing.

Single-Side Polished

Single-side polishing is commonly used for substrates and components requiring one functional optical or processing surface.

Double-Side Polished

Double-side polishing is suitable for windows, wafers and components requiring transmission through both surfaces.

Frosted Surface

Frosted sapphire can be supplied for light diffusion, appearance control or non-reflective structural use.

Optional Optical Coatings

Sapphire optical windows may be supplied with coatings according to the operating wavelength.

Available coating options may include:

• Single-wavelength AR coating
• Broadband AR coating
• Dual-band AR coating
• UV optical coating
• Visible-light coating
• Infrared optical coating
• Customized coating design

Please provide the wavelength range, angle of incidence, operating environment and transmission target when requesting a coated product.

Quality Control

Each sapphire component is inspected according to the approved drawing and order specification.

Typical inspection items include:

• Material appearance
• Crystal orientation
• Outer dimensions
• Диаметр
• Толщина
• Плоскость
• Параллелизм
• Surface roughness
• Surface quality
• Edge chips
• Трещины
• Chamfer dimensions
• Hole size and position
• Optical transmission
• Coating appearance
• Packaging condition

Material certificates and dimensional inspection reports can be supplied when specified in the purchase order.

Design Considerations

Sapphire is very hard but can be sensitive to concentrated impact and unsuitable corner designs. Product designs should consider:

• Avoiding excessively sharp internal corners
• Providing reasonable edge chamfers
• Maintaining sufficient wall thickness
• Avoiding holes too close to component edges
• Controlling thermal gradients during use
• Using suitable mounting and sealing methods
• Preventing concentrated mechanical loading
• Defining only necessary precision tolerances

Early drawing review can help reduce machining risk and production cost.

Information Needed for Quotation

Часто задаваемые вопросы

Is sapphire glass the same as normal glass?

No. Sapphire is a synthetic single-crystal aluminum oxide material. The term “sapphire glass” is commonly used in the market, but its structure and performance are different from conventional glass.

Can you produce sapphire components from customer drawings?

Yes. We can review customer drawings and manufacture sapphire wafers, windows, plates, rods and special-shaped components.

Are different crystal orientations available?

Yes. C-plane, A-plane and R-plane sapphire products are commonly available. Other orientations should be reviewed according to the required dimensions and quantity.
