Lanthanum Fluoride Crystal Substrate is widely used in the infrared and ultraviolet window prism substrate. Stanford Advanced Materials (SAM) can offer a variety size of LaF3 Single-crystal Substrates.
Lanthanum Fluoride Crystal Substrate is widely used in the infrared and ultraviolet window prism substrate. Lanthanum Fluoride Crystal Substrate is sometimes used as the “high-index” component in multilayer optical elements such as ultraviolet dichroic and narrowband mirrors.

There are very few high-index materials in the far UV. LaF3 is one. Lanthanum Fluoride Crystal Substrate is also a component of multimetal fluoride glasses such as ZBLAN. It is also used (with europium fluoride, EuF2) in fluoride selective electrodes. LaF3 Substrate can be used for the preparation of modern medical image display technol.
