摘要： An optical material includes lithium tantalate, and a molar composition ratio of lithium oxide and tantalum oxide (Li2O/Ta2O5) in the lithium tantalate is in the range of 0.975 to 0.982. Since an optical material having a high refractive index is provided in an optical unit, at the same focal distance, a lens thickness can be significantly reduced. As a result, an optical electronic component and an optical electronic device including the optical material has a reduced size and thickness and is highly functional.
