Abstract
THE existence of two types of diamond was suggested in 1934 by Robertson, Fox and Martin1. The distinction between these types is based, among other differences, on the location of the absorption cut-off in the ultra-violet. Thus a type I diamond is transparent to radiation down to about 3000 A., whereas in a type II diamond this limit is extended to 2250 A. In diamond investigations the term ‘absorption cut-off’ has been used very frequently and conclusions have been drawn without taking the thickness of the specimens used for experiment into account. The seriousness of this omission is evident in this communication, where some of the results of absorption measurements on thin diamond plates are given.
