Abstract

In the UK a procurement specification for optical germanium has been evolved. The prime requirements for optical grade germanium are stated in terms of conductivity type, resistivity range, refractive index, refractive index temperature coefficient, MTF performance, transmittance, optical absorption and fracture stress. The general aim of the specification is to relate the properties specified as closely as possible to the performance of the material in component form. In the present paper numerical data for each of the above parameters is given together with discussion on the means by which the data has been evolved as a result of materials characterisation where this is appropriate.
