Sapphire optical component for fiber coupling

Sapphire Half Ball Lens for Stable Fiber Coupling

A sapphire half ball lens focuses or collimates light between an optical fiber and a detector, emitter, or other optical element. Its hemispherical geometry supports compact coupling assemblies, while sapphire combines broad optical transmission with low thermal expansion and high surface hardness.

Interest

Why Sapphire Fits Demanding Optical Assemblies

Material selection affects alignment stability, service life, and optical performance. Sapphire is used where conventional optical glass may face abrasion, temperature change, or repeated handling.

Optical Transmission

Useful transmission from ultraviolet through infrared wavelengths supports a range of sensing and fiber-optic applications.

Mohs 9 Hardness

A hard optical surface helps resist scratching during assembly, cleaning, and operation.

Thermal Stability

Low thermal expansion helps reduce dimensional drift when operating temperatures change.

Geometry and dimensions can be matched to the coupling layout

How the Half Ball Lens Manages Light

The curved surface refracts incoming or outgoing light so it can be focused or collimated over a short optical path. In a fiber coupling device, the lens can help match the fiber output to a photoelectric sensor or another optical component.

  • Compact geometry for space-limited assemblies
  • Controlled curvature for repeatable alignment
  • Optional AR coating for the specified wavelength band

Custom Dimensions and Optical Finishing

The existing product range supports diameters from 2 mm to 50 mm. Final geometry, tolerances, surface quality, and coating should be defined against the optical design rather than selected from a generic tolerance set.

Desire

Applications in Fiber-Optic and Precision Systems

The lens can be integrated into fiber coupling modules, optical communication equipment, precision detection instruments, and compact optoelectronic sensing devices.

Fiber Coupling Modules

Focus or collimate light between the fiber end and the next optical element.

Optical Communication

Support compact transmitter, receiver, and signal-routing assemblies.

Precision Detection

Use stable geometry in instruments exposed to temperature change or repeated operation.

Optoelectronic Sensors

Fit small sensing packages where durability and optical access are both required.

From Drawing Review to Finished Lens

  1. 1

    Review

    Confirm diameter, height, curvature, clear aperture, wavelength, and assembly conditions.

  2. 2

    Machine and Polish

    CNC spherical machining and optical polishing establish the required geometry and surface.

  3. 3

    Coat if Required

    Apply the specified AR coating for the operating wavelength and surface selection.

  4. 4

    Inspect

    Check dimensions and optical requirements before shipment.

Sapphire Half Ball Lens Questions

What diameter range is available?

The existing product information states that custom diameters from 2 mm to 50 mm are available. Feasibility depends on the complete geometry and tolerances.

Can the lens receive an AR coating?

Yes. Single- or double-side AR coating can be discussed for the specified fiber-optic wavelength band.

Why use sapphire instead of optical glass?

Sapphire offers high surface hardness and low thermal expansion, which can help in assemblies exposed to abrasion or temperature change.

What information is needed for quotation?

Provide a drawing, material and coating requirements, operating wavelength, quantity, and any inspection or documentation needs.
