Used in the preparation of optical coatings and fluoride glasses due to its low refractive index and high transparency in the ultraviolet and infrared regions.

Employed in spectroscopy as a component of prisms and windows in specialized instruments.

Serves as a catalyst or reagent in certain organic synthesis processes involving fluorination.

Utilized in research settings for the development of cadmium-based semiconductor materials.

Also found in some laser systems where fluoride crystals are required for beam delivery or frequency modulation.
