Anti-reflective coating has many benefits, but it is an add-on so your anti-glare glasses will cost more. If you’re considering it, talk to your eye doctor so they can help you decide if it’s worth it for you.

ZEISS Dimension lenses can be used with all common sensor formats that are offered in combination with the C-mount. The range of compatible formats extends up to 4/3” sensors. All ZEISS Dimension lenses make it possible to fully exploit the resolving power of sensors with a pixel size of up to two microns. They stand out due to their high speed with a maximum aperture of f/2, or f/2.8 at 8 mm. This not only brings advantages in low light – the lenses’ high speed makes short exposure times possible, resulting in faster processes.

The ZEISS Dimension lenses feature all ZEISS T* coating. The careful selection of the layers deposited on the lenses ensures both the high and uniform transmission of light from the visible spectral range to the near-infrared wavelength range.

Precision and ease of operation are key factors that make the ZEISS Dimension family stand out. With the help of the innovative adjustment mechanism*, it is easy to compensate for tolerances at the camera mount. In addition to the C-mount’s stable screw connection, locking screws on the focus and aperture rings guarantee a high degree of stability and ensure that the settings remain in the correct position.

You want your glasses to give you the best vision possible. Adding anti-reflective coating to your lenses is one way you can optimize your vision.

The ZEISS Dimension® family meets the highest demands for industrial applications. The lenses developed for use with a C-mount are designed for image sensors up to a size of 4/3” and offer exceptional image quality in a compact, lightweight and rugged aluminum housing. The ZEISS Dimension® family consists of six focal lengths ranging from 8 to 50 millimeters. Almost all ZEISS Dimension lenses have the same outer diameter for reliable planning when mounting them in production facilities.

MAR coatingmeaning

The more light that reaches your eyes, the better you can see. Anti-reflective coating (also called “AR coating” or “anti-glare coating”) decreases the amount of light that is reflected off the front and back surfaces of your eyeglass lenses. This lets more light pass through the lenses and reach your eyes.

A prism is solid with two congruent polygon bases that are parallel and connected by rectangles. Prisms are named by their base shape.

The exact formula of anti-reflective coating depends on the company that makes it. In general, AR coating is made of many very thin layers of metal oxides that are applied to the lens surface. The layers alternate between high and low refractive indexes (the refractive index measures how the lens refracts — or bends — light). The more layers there are, the less amount of light that’s reflected onto the lenses of your anti-glare glasses.

ZEISS lenses need to operate perfectly in extreme conditions, withstanding everything from scorching heat and bitter cold to sandstorms and severe vibrations. The video shows how ZEISS researchers systematically submit lenses to extreme stresses in order to arrive at findings that can help in future lens design and development. The video explains how a lens with fixing screws was tested regarding following norms:

Thanks to ZEISS Dimension lenses’ outstanding image quality, even the smallest structures are clearly resolved. This reduces the demands placed on downstream image processing and makes shorter production times possible. In addition, the lenses’ extremely high image resolution is what makes certain measurements and the ability to collect some data possible at all.

Most regular plastic lenses reflect about 8% of the light hitting the lenses so only 92% of available light enters the eyes. AR coating eliminates almost all reflections so up to 99% of light passes through your anti-glare glasses and reaches your eyes.

The majority of lenses with anti-reflective coating have a very light tint, which is usually green or blue. The color depends on the brand of coating that’s on your lenses.

The mounting position of lenses on cameras in industrial applications can vary greatly. This often leads to scales being in inconvenient positions that are difficult to see during operation. To ensure optimum legibility at all times, the azimuth alignment of the scales can be corrected. Doing so is as easy as loosening three screws, moving the scales into the desired position and retightening the screws.

To ensure maximum image quality, eliminating interference from external vibrations is extremely important. This is why ZEISS Dimension lenses are equipped with three locking screws each on the aperture and focus ring. They prevent the lens settings from shifting unintentionally as a result of vibrations. All ZEISS Dimension lenses have been extensively tested for reliable performance under permanent mechanical stress and meet the stringent requirements of DIN ISO 9022.

Most premium AR lenses include a surface treatment to seal the anti-reflective layers and make the lenses easier to clean. These treatments also repel water so you won’t get water spots on your lenses. Some lens surface treatments repel both water and oil from your skin.

Light is critical for good vision. When light enters your eye, it hits the retina — the light-sensitive layer of tissue at the back of the eye. Photoreceptors cells in the retina turn the light into electrical signals. Those cells send the electrical signals to the optic nerve, and the optic nerve sends them to the brain. The brain turns those signals into the things you see.

AR coating is especially beneficial on high-index lenses. These lenses are thinner and lighter than regular plastic lenses. They can reflect up to 50% more light than regular plastic lenses so less light reaches your eyes.

Precision is crucial in industrial applications. For maximum image sharpness, the lens and camera must work perfectly together. The smallest deviations in the flange focal distance can have negative effects on imaging performance. This is why the ZEISS Dimension lens family is equipped with the innovative adjustment mechanism*. The benefit of this system is that it allows the back focus distance to be corrected by up to +/- 0.2 millimeters without having to disassemble parts of the lens.
