WebThis parameter ranges from less than 100:1 for economical sheet polarizers to 10 6 :1 for high quality birefringent crystalline polarizers. The extinction ratio typically varies with wavelength and incident angle and must be evaluated along with other factors like cost, size, and polarized transmission for a given application. An optical filter selectively transmits one portion of the optical spectrum, while rejecting other portions. Commonly used in microscopy, spectroscopy, chemical analysis, and machine vision, … See more While filters share many of the same specifications with other optical components, there are a number of specifications unique … See more To aid in understanding the similarities and differences between the large variety of optical filtersavailable today, consider ten of the most popular types.
