Fluorides

Materion Advanced Chemicals, formerly CERAC, Inc., offers high quality fluorides manufactured with the specific application central to your approach.

Aluminum Fluoride is a promising hyperspectral Low Index Deposition Material for a potential alternative to Magnesium Fluoride in thin film design.

CIROM-IRX™ can be used as an alternative to Thorium Tetrafluoride in infrared designs by E-beam or Thermal deposition.

Materion has developed several varieties of Magnesium Fluoride low-index materials to cover the ultraviolet (UV), visible (VIS), and near infrared (NIR) regions of the spectrum.

Thorium Fluoride continues to be a critical IR low-index coating material for a growing number of intense laser applications, where thermal absorption is the key factor in optical component failure.

While the radioactivity of Thorium Fluoride remains a key driver for developing alternatives, it still offers the lowest absorption and low-index material for optics with the most sensitive designs.

Ytterbium Fluoride has been developed as an alternative to both Thorium Fluoride and Ytterbium Fluoride. This is a low-index film material that exhibits good transparency from UV to far-infrared regions. The films are insoluble and exhibit low stress, making Ytterbium Fluoride a useful substitute for Thorium Fluoride in many infrared applications.

While perhaps the most prolific alternative to Thorium Fluoride by itself or in specialty mixtures, Yttrium Fluoride enables the development of Infrared Band Pass and Broad Band Anti-Reflection (ARs) from Thermal or E-beam approaches.
