Abstract
THE introduction of lithium fluoride in synthetic crystal form (a technique developed by Dr. D. C. Stoekbarger1 and his colleagues at Massachusetts Institute of Technology) has been the means of filling a much-needed want in optical materials. In Great Britain little use appears to have been made of this material. Its chief characteristic is its high transparency from wave-length 1200 A. up to 20,000 A.; furthermore, its homogeneity is excellent (even in large crystals) and in this respect is superior to fluorite or quartz.
