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.
Optical Wafer Material Comparison
| Material | Typical Use | Key Strength | Product Page |
|---|---|---|---|
| Lithium niobate | Electro-optic and photonic devices | Strong electro-optic and nonlinear optical properties | Lithium Niobate Wafers |
| Lithium tantalate | SAW, pyroelectric, and nonlinear optical devices | Useful crystal properties with good thermal and chemical stability | Lithium Tantalate Wafers |
| Quartz single crystal | Optical, piezoelectric, and UV-related components | High optical quality and stable crystal behavior | Quartz Single Crystal Wafers |
