Description
It has been known since the 1950s that potassium tantalum niobate crystals have a very large electro-optical effect; i.e., a large change in refractive index with a relatively low applied voltage. To be used as an optical device, KTN must be a single crystal so that incident light is not scattered.
The giant electro-optic effect of potassium tantalum niobate (KTN) crystals has been exploited.
Products Description
Potassium tantalum niobate crystals are used in the following applications:
- KTN deflectors
- 200kHz OCT wavelength scanning light
- Vertical focal length lenses
