You can suppress reflections on glass fronts pretty well if they result in polarised light. That tends to be the case completely when the reflection on the glass surface occurs at "Brewster's angle", an oblique angle. So roughly speaking you need to shoot "half sideways" at the glass reflection for best effect.

Optical filters play a crucial yet often overlooked role in semiconductor manufacturing, where nanoscale precision can make or break a product.

Light reflected from non-conductive surfaces such as glass undulate mainly in one plane. When first studied, scientist falsely concluded that light waves must have a north and south pole, like a magnet. While false, the term polarized and un-polarized stuck. When light rays are reflected from the polished surface of glass windows and showcases, it will likely be polarized. Polarizing filters pass light waves that vibrate in a single plane and block light waves that vibrate in opposing planes. Consider a jump rope passed through a fence with a missing picket. The jump rope when plucked only vibrate up/down and not side-to-side.

Raman filters are ideal when you need higher transmission values, fast transitions, and superior blocking to keep out unwanted photons.

Many modern biomedical technologies—from PCR to flow cytometry, DNA sequencing to clinical chemistry analysis—rely on the clarity of fluorescence signal detection.

In the consumer electronics market, optical filters offer enhanced imaging capabilities for displays, cameras, and smartphones.

Astrophotography uses spectral imaging to measure diverse properties of astronomical objects including molecular composition, ionization state, redshift, and temperature.

In the dynamic landscape of rapid product development, transforming ideas into prototypes swiftly is essential across diverse applications.

I wonder if the same polarizer filters we use for making the underwater look clear instead of the sky reflections blurring the water can be used for that situation.

Our filters optimize industrial processes like machine vision and quality control, fostering efficiency and innovation across diverse sectors.

The fine slit structure of the polarizer allows vertical waves to pass through and horizontal waves to be absorbed and not transmitted.

Yes. Here's an example image with very similar conditions to the post you linked to. In this case they are using a circular polarizing filter:

Polarisers can be rotated. It's worth pointing out that you can also use them for increasing the visibility of reflections by rotating them such that the polarised reflection passes through the filter completely while non-polarised light gets reduced by half in comparison.

Automation is reshaping the global industry, fueled by demands for greater manufacturing productivity, agile supply chains, and growing adoption of new, demanding industrial standards.

We manufacture high-quality, narrow-band spectral line filters for detecting ionized sulfur, oxygen, and other elements.

So is it possible to get rid of these glass reflections by using polarizers? Is there a difference between regular polarizers that if what i heard is correct change the picture as you tilt the camera (just like how twisting polarized sunglasses makes the digital displays go black) and the circular polarizers when it comes to this?

If you don’t see what you are looking for, please contact us. We have a large inventory of filters and a knowledgeable staff ready to help you design and build a filter to meet your specifications.

CPL filters do not differ in their photographic properties from linear polarisers; they are merely friendlier to metering and autofocus. But in essence they are just linear polarisers with a quarterwave plane behind them that converts the passing linearly polarised light to circularly polarised light which some parts of a camera are better equipped to deal with.

Filters play a crucial role in enhancing clarity, color accuracy, and contrast in machine vision applications where details matter.

Light travels following a wavelike path. Water waves on a pond travel in a similar manor however, water waves undulate up/down whereas light waves freely vibrate in every possible plane. Such light wave behavior is said to be un-polarized. When light waves are reflected from some surfaces, they often become polarized. Polarized light wave vibrate however the direction of their undulation is altered.
