1. CIROM TM IRX A Non-Radioactive Replacement for ThF4

   A non-radioactive replacement for thorium fluoride, ThF4, is now available.  CIROM-IRX™ can be used for applications ranging from low-loss laser mirrors to filter and AR coatings.

2. Ytterbium Fluoride YbF3

   Ytterbium fluoride, YbF3, is a low-index film material that exhibits good transparency from the UV through far-infrared regions.  The films are insoluble and show low stress, making YbF3 a useful substitute for ThF4 in many IR applications.
