Abstract

Some well known relations between thicknesses and indices of a stack of optical layers allow to obtain very good polarisers of light. One of the most famous is the Mac Nellie cube polariser. In this case one of the hypotenuse face of two isosceles right angled prism is coated with a polarizing deposit, and then cemented to the other hypotenuse face, This polariser can be used on a large spectral range located in the s vibration stop band, Unfortunately the insertion losses for the p vibration are important when the angular field is larger than ± 2 degres.
