Abstract
A protective layer is prepared for water soluble optical elements. A process for obtaining clear thallium iodide (TlI) films of 1 to 2 micron thickness on potassium chloride (KCl) substrate. The high index of refraction (2.34 - 2.46 at 10.6 microns) makes this coating material attractive as a component in an antireflection system of coatings.
