TLDR
It is demonstrated that by proper choice of glasses for the arms of the Michelson the wide field condition can hold over a large spectral and large temperature range and minimization of the wavelength sensitivity to temperature.Abstract:
A 100-mA analog birefringent element has been built from a polarizing wide field solid Michelson interferometer. The analog element behaves on-axis identically to a crystal element but has the field characteristics of a wide field Michelson. It is demonstrated that by proper choice of glasses for the arms of the Michelson the wide field condition can hold over a large spectral and large temperature range. Most important, proper choice of arm materials allows minimization of the wavelength sensitivity to temperature. A reduction of a factor of 10(2)-10(3) compared to birefringent crystals can be achieved.read more

TL;DR: Optical birefringent filters, which depend for their action on the interference of polarized light, can be designed to transmit very sharp bands (down to a fraction of an angstrom in width) as mentioned in this paper.

TL;DR: The field of view characteristics of wide field birefringent elements are compared with those of the Fabŕy-Perot (F.P.), Michelson (MI), and wide field Michelsen (WFM) interferometers and it is shown that by proper choice of material WFB elements can have angular characteristics identical with WFM interferometer.
