Optische Untersuchungen des Aufbaus von Kryolith-Aufdampfschichten

The formula whch has been proposed by Chandrasekhar to express the dependence of the rotatory power on wavelength has the form where Ki is a constant and A, is the characteristlc wavelength. This quadratic formula was prevlously denved for crystals with space group of symmetry Dt or its enantiomorphous D:. However, Chandrasekhar and other authors have shown that this formula may be used also for crystals which belong to other groups of In this paper we have removed certain simplifying assumptlons of Chan-symmetry. drasekhar's model and in this case obtain a more general formulaOnly 111 the special case where Kt2) = 0, that is in the case of the equality of oscillator strengths of both normal modes of vibrations, we obtain Chandrasekhar's formula. The applicabdity of our equation to known cases is discussed.

“…(After Hass and Ritter 1967. ) Of recent years there has clearly been an increase in the number of materials found to be suitable for optical coating, and this has led to a relaxation of the restrictions previously imposed on the design of filters by the lack of materials with desirable refractive index values, Another useful development in this regard are the results of investigations (Koppelmann et al 1961, Fujiwara 1963 of the optical properties of films of two dielectric materials mixed in various proportions to provide refractive index values ranging between those of the pure materials. However, the restrictions imposed on the design of filters by the availability of only a limited set of materials are frequently over emphasized; after all, one of the main attractions of optical filter technology lies in the fact, already stated in the introduction to this review, that a wide variety of filtering properties can be obtained by the use of only two or three materials and the application of ingenious design.…”
