Description

LaF3 Infrared Crystal is an optical material with high transparency from 0.2 to 10.5 um. That span covers UV, visible, and infrared in one material. The crystal has a melting point of 1493 C and is insoluble in water. The material is lanthanum fluoride.

LaF3 Infrared Crystal properties

The 0.2-10.5 um transparency window is the headline: few materials stay clear across that range. A 1493 C melting point signals refractory stability. Consequently, the crystal suits demanding optical environments.

Optical handling notes

Fluoride crystals prefer dry handling. Therefore, standard desiccated storage keeps surfaces pristine.

Applications across four fields

In the medical field, it supports scintillator requirements. It also serves fluoride glass fiber optics and rare earth infrared glass. For chemical analysis, it forms the sensing membrane of fluorine ion selective electrodes, measuring fluorine ion concentration in solution. In metallurgy, it helps manufacture special alloys and electrolytic lanthanum metal.
