Interference birefringent filters fabricated with low cost commercial polymers

Abstract: We discuss a simple method for fabricating interference birefringent filters using common cellophane tape layers. Cellophane tape layers can be superimposed with different orientations to generate different spectral responses. We demonstrate this behavior with a portable spectrophotometer. This technique is a simple and inexpensive way of investigating the optical properties of birefringent filters.

“…11 The Solc filter waveplate arrangement is shown in Fig. It is possible to produce an approximate flattop response using three waveplates whose thicknesses are in the ratio ͑d ,2d ,2d͒ and whose orientations relative to the polarizer are ͑45°, −15°, 10°͒.…”

“…The retarder is inserted between two parallel or crossed linear polarizers, with the principal c-axis oriented with a relative angle of 45°with respect the transmission axes of the polarizers. In this situation, the normalized transmission output is given by [4]:…”

“…However, characterization of their spectral retardance properties can be very valuable for several reasons: 1) the retarder can be used at wavelengths different to the original design; 2) the retarder can be applied to build spectral birefringent filters, which are based on the wavelength variation of the retardance [4], 3) it allows the simple identification of the ordinary and extraordinary neutral axes of the retarder [5], and 4) the retardance modulation of tunable LC retarders can be characterized [6,7].…”
