Filters can be used to attenuate light either evenly across a certain portion of the spectrum (neutral density, polarizing, retarders, etc.) or unevenly (ie. Interference, dichroic, color). Typical applications for filters involve improving contrast or signal-to-noise ratio (imaging and non-imaging

Comparison of the UV flow dichroism spectra of TMV and several of its mutants
Abstract The dichroic ratio spectra of TMV and four of its mutants (YTAMV, GTAMV, HR, and CV4) were determined from 320 to 240 nm.
A Gaussian disorientation model for interpreting linear dichroism measurements of DNA-drug fibres and films
Using this model we have obtained analytical expressions for the dichroic ratio without resorting to computer simulation techniques or numerical integration methods, and used them to interpret the results of experiments using DNA-phenanthridine fibres.
ANALYSIS OF THE COMPLEX BAND SPECTRUM OF P700 BASED ON PHOTOSELECTION STUDIES WITH PHOTOSYSTEM I PARTICLES
The most prominent feature in the spectrum of the dichroic ratio is the symmetrical pole at 687 nm.

Analysis of molecular orientation and internal stresses in extruded plastic sheets
Measurements of attenuated‐total‐reflectance infrared dichroic ratio for the surface molecular orientation, birefringence for the orientation stress distribution in the thickness direction, and free shrinkage ratio for the overall frozen‐in stresses were carried out to determine the amount of orientation stresses in the …
Molecular organization of DNA in chromosomes
Abstract Metaphase chromosomes of Chinese hamster and lampbrush chromosomes of Triturus viridescens were studied for DNA arrangement by polarized fluorescence microscopy and by linear dichroic ratio measurements.

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).
Absorption properties of a photostable pigment (P456) in rhabdomere 7 of the fly
It seems plausible, however, to assume that the dichroic ratio within an absorption band should be constant.
