Engineering pain points we resolve

Core Pain Points Facing AR/VR Optical Engineers

Ordinary protective glass causes polarization distortion and damages uniform AR/VR imaging effect

Thin optical substrates are vulnerable to scratches during assembly and daily end-user usage

Standard optical coatings trigger high surface reflection, lowering display contrast and visual experience

Few suppliers deliver ultra-thin sapphire panels with consistent optical uniformity and low birefringence control

Direct engineering overview

Advantages of Felix Glass Low Birefringence Sapphire Eyepiece Cover

We select imaging-grade low birefringence single crystal sapphire as base material, eliminating polarization distortion risks which commonly exist in ordinary optical glass. The Mohs Grade 9 hardness offers superior wear resistance to protect internal eyepiece optical elements. Custom broadband AR coating optimizes transmittance within target wavelength band, suppress ghost image and surface reflection for clearer AR/VR visuals. We support ultra-thin wafer processing starting at 0.1mm thickness, satisfying compact HMD lightweight design requirements. All manufacturing processes are finished inside Class 100 dust-free workshop to guarantee consistent optical parameters batch by batch.
