1. What is Potassium Tantalate Niobate Crystal?

Potassium Tantalate Niobate (KTN) is a solid-solution perovskite oxide crystal generally represented by KTa₁₋ₓNbₓO₃. It combines tantalum and niobium in a single crystal and exhibits strong electro-optic and nonlinear optical properties.

2. What is KTN Crystal used for?

KTN crystals are used in electro-optic modulators, optical beam steering, tunable optics, laser systems, optical switching, nonlinear optics, photonics, and advanced optical-material research.

3. Can the tantalum-to-niobium ratio be customized?

Yes. The Ta/Nb composition is one of the most important specifications for KTN crystals, as it influences the crystal's dielectric, ferroelectric, and electro-optic behavior.

4. Can KTN crystals be optically polished?

Yes. Optically polished KTN crystals can be supplied with controlled surface quality, flatness, dimensions, and optical specifications for photonics and electro-optic applications.

5. Can custom crystal orientations and dimensions be supplied?

Yes. REG Metals can source KTN crystals with custom orientations, dimensions, thicknesses, surface finishes, and electrode configurations according to application requirements.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting Ta/Nb composition, purity, crystal orientation, dimensions, surface finish, optical properties, and other applicable crystal specifications.
