Does it mean that only the circular polarized light goes through or at the opposite, only the circular polarized light is stopped?

You have seen, water waves ungulate in an up and down direction. Light waves are not limited as to the direction vibration. Light waves can and do vibrate like water waves but their direction of vibration can be in any orientation. We are taking up – down – left – right and angled (not parallel to the horizon) ect. Scientists that first discovered that light moved with a wave motion compared the up and down trails to the poles of a magnet. They reasoned that light must a north and South Pole. Investigation showed that when light transversed some transparent material or when light was reflected off some surfaces, the direction of vibration was changed, they said the light ray had been polarized. The north pole south pole idea failed to materialize the jargon remained thus “polarization”.

But what does circular mean? Does it mean that only the circular polarized light goes through or at the opposite, only the circular polarized light is stopped?

In photography we use the polarizing filter to darken blue sky making the white clouds stand out. The polarizer adds saturation to color images without changing the basic color of the vista. The polarizing filter mitigates reflections from water and glass and many other surfaces. The polarizing filter cuts through haze in the air clarifying the images of distance landscapes and views from high flying airplanes. The polarizing filter is likely the most useful of all optical filters for the camera.

Neither. It means only light polarized in one direction is allowed to pass. Then the quarter-wave plate underneath the polarizing filter repolarizes it in a kind of circular way.

Microscopeparts and functions

Modern digital cameras have auto focus and auto exposure mechanisms. Many times a polarizing filter is in the light path used by these devices. For this reason, mounting a polarizing filter can defeat this automation. Circular Polarizer to the rescue: Two filters are sandwiched together. The first is a regular “linear” polarizer. This filter does the intended job. Only the select rays vibrating in the correct ordination transvers the filter, a second filter called are “retarder” is next in line. This filter scrambles the light, now it vibrates in all planes. This combination will not harm the sensors, they auto focus and measure exposure as if nothing had interfered.

"Circular" polarizing filters allow the partial removing of non specular reflections like glass, water or snow reflections.

Microscope eyepieces are critical to a user’s experience with a microscope. Also called an ocular lens, the eyepiece lens of a microscope produces a magnified image in conjunction with the microscope objective, which enables the human eye to see the specimen under the scope. Add microscope accessories to your purchase of an ocular lens like eyeguards. These eyeshields play a role in providing comfort to the user, reducing eye strain when using the eyepieces. Eyeguards for microscope eyepieces reduce the glare, block external light sources, and align the user’s eyes to the ocular lens.

Our microscope eyepieces can be used with or without prescription glasses, as the ocular lens has eyecups that can either be taken off completely or folded over to accommodate eyewear. The eyepiece ocular lens provides a standard 10x magnification starting point when viewing specimens. Our ocular eyepieces work well with both compound and stereo microscopes. The microscope eyepieces are compatible with many of our microscope brands, including ACCU-SCOPE, LABOMED, Olympus, and Leica Microsystems. We also offer microscope eyepiece cameras to capture images of the specimen being observed under the microscope.

A transparent crystalline mineral called Islandic Spar was observed to split a light beam into two different paths. Other minerals acted as if they were ruled with closely parallel lines. Edwin Land mixed these into a plastic and made lenses for sunglasses. His sunglasses only allowed light to transverse if the direction of vibration aligned with the crystals. Now light changes its direction of vibration upon reflection from some objects. Same thing happens as light transverses air that contains water vapor and or dust. The polarizing sunglasses thus stop some light rays and pass some light rays. The result, a great deal of glare is mitigated.
