Politicalpolarization

Polarizers absorb incident light oscillating in all but one plane - its polarization axis - yielding linear polarization. Another example of polarization is the partial polarization of light reflecting from a plane surface, an effect less dramatic than a polarizer element. Linear polarization of a randomly polarized light source reduces the intensity of the source theoretically by 50%, and in practice closer to 60-65%. Light that passes through two polarizers with orthogonal polarizing axes will be completely attenuated. However, the almost total elimination of hot spots and glare is exactly what makes a polarizer effective in evening out illumination levels within a field.

Electricpolarization

By considering light as an electromagnetic wave, we realize that in three-dimensional space a wave can oscillate up and down, side to side, or anywhere in between. Incandescent, fluorescent, LED, and many laser light sources are randomly polarized. In other words, the oscillating angle or plane of light from each point on the light source is varying with time. Taken as a time average, therefore, randomly polarized light sources continuously output all angles of polarization.

Adding UV-C lighting to a cooling unit increases overall indoor air quality while improving the performance of the unit. Specifically, the UV-C light option will protect your unit from mold and other bacterial growth.

Stress Evaluation: Stress, or unwanted refractive index variations, causes a rotation in the angle of polarization. Viewing an unstressed clear object between crossed polarizers should yield a completely dark field. However, when stress is present, the localized changes in refractive index actually rotate the angle of polarization to give varying degrees of transmission - even different amounts of transmission for different colors.

Air handlers are particularly susceptible to microorganism growth. Fungus, mold, and bacteria can be pulled in from the cellar or outside. Once inside the unit, the organisms have a perfect place to grow due to the moisture built up in the compartment; from there, the organisms are pushed back into the cellar. Our UV-C lighting system is designed as an add-on feature that will target the buildup of these microorganisms.

Contrast Enhancement: Ring light guides are popular for their even, diffuse illumination. However, glare or reflection of the ring itself may occur. Polarizing the ring output and the lens separately can reduce these effects, and bring out surface details.

Shown are examples of some common polarization of light techniques used in imaging applications. By utilizing a linear polarizer over the light source, the lens, or both, it is possible to eliminate glare from a reflective surface, bring out surface defects or show stress in a transparent object. More detailed information on which type of polarizer is right for your application can be found in our Polarizer Selection Guide.

Eliminating Hot Spots: Hot spots are highly reflective areas within a more diffuse reflecting field. Polarizing the light that strikes these reflective areas, and using a crossed polarizer over the lens, effectively eliminates the hot spots, while evenly illuminating the rest of the field.

Glare From a Plane Surface: Glare from highly reflective surfaces or optical windows is removed by putting a polarizer over the lens. Due to partial polarization of light, the light source may or may not require a polarizing filter in this scenario.

Video and machine vision systems rely on electronic imagers that typically exhibit anywhere from eight-bit to twelve-bit signal-to-noise ratio. Although sufficient for many applications, cameras in this category may be problematic in cases where the field of view includes extremely bright regions or hot spots. Some objects have certain features that are extremely reflective, or objects may be illuminated from an angle that produces intense reflection. Light polarization filters offer solutions to these and other common imaging problems.
