This is an introduction to electro-optical crystals, oxide lens material crystals, and more. Electro-optic crystal KTN (KTa1-xNbxO3) We sell optical devices using KTN crystals such as optical scanners and varifocal lenses, OCT light sources for optical scanner application products, and KTN crystal chips for research and new device applications. KT (KTaO3) crystals KT (KTaO3) crystal is a transparent oxide crystal composed of potassium (K), tantalum (Ta) and oxygen (O). It is a transparent crystal with no properties. SIL literature
