Optical-grade protection for compact near-eye displays

Ultra-Thin Sapphire Cover For AR VR Eyepiece Overview

This 0.1-0.5 mm single-crystal sapphire cover is engineered for AR/VR eyepiece modules that need a thin, hard, optically stable protective window. It combines Mohs 9 scratch resistance, tight thickness control, and a broadband anti-reflection coating for visible and near-infrared imaging paths.

Low Birefringence Sapphire Optical Advantage

Stable image quality

A-plane, low-birefringence material helps reduce polarization-related artifacts and image distortion in near-eye optical paths.

Hard protective surface

Mohs 9 hardness provides durable resistance to scratches from cleaning, assembly, handling, and everyday headset use.

Thin mechanical envelope

Custom 0.1?0.5 mm sections support compact optical stacks while retaining sapphire's chemical and thermal stability.

Full Optical Transmittance Test Data

The following values are target acceptance criteria for the proposed broadband-coated component. Final spectral curves and angle-of-incidence performance are confirmed against the approved drawing and coating specification.

Micro-Size Precision CNC Machining Capacity

Felix Glass supports custom outlines, compact apertures, edge profiles, holes, slots, and alignment features for prototype and production eyepiece assemblies. Manufacturability review focuses on minimum edge distance, corner radius, aspect ratio, and the handling risk of ultra-thin parts.

  • Drawing-based tolerance review
  • Micro-size CNC cutting and edge finishing
  • Fixture planning for fragile thin sections

Broadband AR Coating For AR Imaging Systems

Dual-band optical design

The coating can be tuned for the visible display channel and the near-infrared sensing channel used by eye tracking, depth sensing, or illumination subsystems.

Application-specific optimization

Provide wavelength bands, target transmission, incidence angle, polarization state, and environmental requirements so the coating stack can be matched to the optical system.

Anti-Scratch Performance Compared With Ordinary Glass

Single-crystal sapphireMohs 9

High resistance to abrasion during cleaning, assembly, transport, and repeated field use.

Typical ordinary glassLower surface hardness

More susceptible to visible scratching, depending on glass chemistry, treatment, and coating.

Standard Ultra-Thin Sapphire Thickness Options

0.10 mm

Extreme compactness; drawing review required.

0.20 mm

Thin optical protection for space-limited modules.

0.30 mm

Balanced handling and compact integration.

0.50 mm

Greater stiffness for larger or exposed windows.

Other thicknesses within the stated range can be reviewed for custom production. Practical limits depend on outline size, edge geometry, flatness, and coating stress.

Cleanroom Production Process Standard

  1. 01
    Incoming material control

    Crystal orientation, dimensions, and visible defects are checked before processing.

  2. 02
    Precision machining

    Parts are cut, ground, polished, and cleaned with fixtures suited to ultra-thin sapphire.

  3. 03
    Coating and inspection

    Optical performance, cosmetics, flatness, and critical dimensions are inspected to the agreed plan.

  4. 04
    Protected packing

    Micro components are separated and cushioned to reduce contact and transit damage.

Technical FAQ For AR Sapphire Optics

Why specify low-birefringence sapphire?

Crystal orientation and material selection help limit polarization-related artifacts in sensitive imaging paths. The correct orientation should be confirmed with the optical design.

Can one coating support visible display and NIR sensing?

Yes, a multi-band design can be evaluated when the required wavelength bands, incidence angles, polarization, and transmission targets are supplied.

Is ?0.003 mm available for every geometry?

It is a target for ultra-precision production, but feasibility depends on part size, thickness, edge features, and measurement method. The drawing review establishes the final tolerance.

What information is needed for a quotation?

Send the drawing, quantity, thickness, crystal orientation, wavelength bands, coating targets, flatness, cosmetic standard, and environmental requirements.

Submit Your AR Eyepiece Drawing For Custom Quotation

For a useful engineering response, include the component drawing, annual demand, prototype quantity, optical bands, angle of incidence, coating target, and inspection standard. Felix Glass can then review manufacturability, sampling, and OEM production options for your AR/VR eyepiece cover.
