Beamsplitters Polarizing Cube
PLATE BEAMSPLITTERS: INTENSITY, DICHROIC, POLARIZING, NON-POLARIZING The transparency range of optical cements used to assemble cube beamsplitters limits their spectral application, roughly to between 200 nm and at the best up to 3000 nm. Plate beamsplitters do not require assembly and their applications are only limited by the transparency of the selected substrate. For example, if ZnSe is used as the substrate, then designs of beamsplitters that operate over range from 400 nm up to 15... (read more)

A theoretical explanation of intensity-independent variation of polarisation sensitivity in Crustacean retinula cells
Theoretical analyses of polarisa- tion sensitivity (PS) in crustacean-type banded rhabdoms indicate that if depths of the orthog- onally orientated layers of microvilli are equal, PS should be equal to the dichroic ratio of the rhabdom material (Shaw 1969; Snyder 1973).
