Optical Wafers and Crystal Substrates

Optical Grade Wafers and Crystal Substrates

ATR Crystal supplies optical grade wafers and single crystal substrates for photonics, electro-optic devices, acoustic devices, sensors, nonlinear optics, precision optical components, and research development. Wafer selection depends on crystal material, orientation, thickness, diameter, surface quality, flatness, transmission, and device process requirements.

Frequently Asked Questions

Can ATR Crystal supply custom wafer thickness?

Yes. Custom thickness, polishing, and dimensional requirements can be reviewed according to drawings and material feasibility.

Which wafer material should I choose?

Lithium niobate is often selected for electro-optic and photonic devices, lithium tantalate for SAW and related device work, and quartz for optical and piezoelectric applications. The final choice depends on device physics and process requirements.
