Birefringence is a fundamental optical property exhibited by materials in which the refractive index varies according to the polarization and propagation direction of incident light. These highly optically anisotropic materials are classified as birefringent crystals. At Atr Crystal, we provide a premium selection of high-performance birefringent crystals—including Yttrium Orthovanadate (YVO4) and Alpha-Barium Borate (α-BBO)—expertly engineered to meet the rigorous demands of your advanced optical systems.

Selection guide
| Selection item | What to confirm | Why it matters |
|---|---|---|
| Material and wavelength | Transmission range, birefringence and operating wavelength. | Determines optical suitability and component length. |
| Crystal orientation | Optical axis, propagation direction and drawing reference. | Controls polarization separation and device behavior. |
| Optical finish | Surface quality, flatness, parallelism and coating. | Affects insertion loss, wavefront and long-term performance. |
Manufacturing support
Products can be prepared according to drawings, target tolerance and system integration requirements.
Polishing, coating, wrapping, encapsulation and optical coupling requirements can be reviewed before quotation.
ATR can help match material selection with detector, laser, optical or measurement requirements.
FAQ
Please provide material, dimensions, tolerance, quantity, surface requirements and target application. Drawings are recommended for assemblies and custom parts.
Many products can be customized by size, geometry, polishing, coating, wrapping, packaging or optical coupling requirements.
Start from the required wavelength, radiation type, readout method, operating environment and mechanical constraints. ATR can review the application before quoting.
