Quality and reliability are top priorities at Schneider-Kreuznach. Our filters undergo rigorous quality control to ensure maximum reliability. We use only high quality glass from reputable manufacturers to achieve very low manufacturing tolerances. As a result, our filters are of consistently high quality. Their use allows you to accurately reproduce results, as the filters will perform nearly identically even after years of use.

A superwide-angle (aka ultra-wide) FOV captures the full 180 degrees in front of it. Some of them can even see the entire 360 degrees around them.

Schneider Kreuznach polarizers are designed to fulfill industrial requirements. They are made of dichroic laminated polarizing polymers cemented between 2 slides of protective glass. Additionally we offer polarizing film for larger sizes or customized shapes and flexible solutions. Polarizing Films consist of long chain polymers, which are aligned by a stretching process to produce the polarization effect. The polarizing film is covered on both sides with cellulose triacetate (TAC) for protection and is therefore mechanically stable. Call us to discuss your OEM and custom requirements.

Our industrial optical polarizer filters are tested to DIN standards to ensure they meet stringent environmental requirements. These tests check the durability of the polarizer filters, their resistance to temperature changes and their ability to withstand exposure to harsh chemicals and other environmental stressors. This ensures that the polarizer filters are up to the task in demanding industrial applications, providing consistent performance and reliability over time.

The IF AUF and IF AUF MRC linear polarising filters are characterised by a high degree of polarisation. This results in a high extinction of the reflected light component in the visible light range (VIS, 420 nm to 750 nm). This suppresses unwanted reflections. The result is a better image and a higher level of contrast. Polarising filters can also make things visible that are otherwise invisible, such as tension in plastics. IF AUF filters are also available with an MRC coating to reduce reflections at the air-glass interface.

Sometimes you’ll want a wide field of view, and sometimes you’ll want a narrow one. But it’s vital that you pick the correct one for the job.

At this point, the usefulness for security purposes plummets. With a range between 10 and 25 degrees, the field of view on a telephoto camera is just too small, despite the fact that it captures subjects in much greater detail.

Axicons are used to transform the collimated light into a ring or to create an approximation of a Bessel beam. from 176 $.

A telephoto field of view is great for zooming in on a particular subject and capturing crisp details, but it’s nearly worthless for monitoring a room or outdoor space.

Camera height and positioning are crucial, too. Finding the right height for your camera—generally, either tabletop or up high, looking down—will allow you to maximize the FOV that you’re working with.

The SN2-Mount is designed for polarizers and achieves highest possible aperture, avoiding vignetting in machine vision systems. Its unique locking mechanism fixes the correct orientation, even in typical industrial environment. The filters are glued into the mount to secure them against vibrations when integrated into robots or production lines. Ideal to be used in automated fabrication.

Robotic vision can identify objects, measure distances and track motion, enabling robots to perform complex tasks autonomously.

A camera’s field of view is not an independent variable. The size of the lens, the physical distance between the camera and the subject, mounting height, and placement all affect it. Your job—or the job of the security personnel you hire—is to consider them all.

Too high, and it may be too far away to capture specific details. Too low, and you’ll lose coverage. You’ll have to experiment.

The P-W 76 and P-W 64 polarizing films feature a high contrast (erasure) of 10,000:1 (P-W 76) and 40,000:1 (P-W 64), respectively. These films can be used to reduce interfering reflections in the visible range of 430 nm to 780 nm from reflective surfaces or to make stress patterns visible on transparent plastics. They are also used to enhance the contrast of images. The films can be cut into any shape using a laser cutter.

That may sound ideal for security purposes, but there’s a catch. A superwide-angle camera warps the image and creates a fisheye effect like you see when looking through a peephole. They can be useful when you want to capture as much of the scene as possible, but it comes at the expense of some detail and clarity.

As the name implies, this is the field of view for most cameras. It has a viewing angle of 25 to 60 degrees. You’ll only capture one-third of the scene at most, but with much greater detail and clarity, as objects and people appear closer to the camera. As far as security goes, a standard angle can be quite effective in a small room or if you’re only interested in capturing a specific section of the overall scene.

By experimenting with security camera placement, you can usually reduce or eliminate the blind spots created by the reduced field of view. For example, a camera mounted high in the corner of a room will capture most, if not all, of the scene, but one mounted in the middle of a wall will have blind spots on both sides of it.

Where is polarizer filter used? In industry, polarizing filters are used in a variety of applications where polarized light is critical. For example, in imaging applications such as microscopy, polarizer filters are used to improve contrast and image quality by selectively blocking or transmitting polarized light waves. They are also used in LCD displays to control the polarization of light passing through the liquid crystal cells, enabling the production of high-quality, high-contrast displays.

A security camera viewing angle is how much a camera can “see” of the 180 degrees in front of it. It’s closely connected to the size of the lens. The bigger the lens, the smaller the field of view, but the more detail you’ll be able to capture.

What is the function of a polarizer filter? A polarizing filter, also called a polarizer, consists of a polarizing film that allows partially polarized light to pass through. This eliminates reflections and increases contrast.

A wide-angle camera checks the most boxes: field of view up to 110 degrees—sometimes even more—without the distortion that comes with a superwide-angle. And while it shows less detail than a standard or telephoto viewing angle, you can make up for some of that with a higher resolution—the number of pixels per inch—and quality components. A high-definition camera with a resolution of 1080p, 2K, or 4K can boost image clarity without having to sacrifice too much from the field of view.

To see that in action, grab your smartphone, open the camera, and point it at whatever is in front of you. The camera “sees” part of the scene, but not the whole thing. Next, zoom in on something. You’ll be able to recognize greater detail, but you’ll have even less of the scene on your screen. The viewing angle has shrunk.

With a range typically between 60 and 110 degrees (or more), a wide-angle FOV sacrifices some coverage for better detail. It’s ideal for security cameras in that sense.

If you’re looking for coverage of a large area like your backyard or parking lot but aren’t overly concerned with the crispness of the image, you can stop here. Just be aware that superwide-angles don’t usually capture enough detail to identify individuals.

A camera is a camera is a camera, right? Yes. And no. While they all basically function in the same manner, cameras can differ in important but often forgotten ways. Camera A might be perfect for a task that Camera B can’t or shouldn’t do. For example, take the camera field of view (FOV), also known as the viewing angle. You’ve likely seen it listed in degrees as part of a camera’s specs. But what exactly is it?
