The fisheye lens is a wide-angle lens with a special optical design, which can show a huge viewing angle and distortion effect, and can capture a very wide field of view. In this article, we will learn about the characteristics, applications and usage tips of fisheye lenses.
1.Characteristics of ...
1.What is a low distortion lens?
What is distortion? Distortion is mainly a term used for photographic images. It refers to a phenomenon in the photography process that due to limitations in the design and manufacturing of the lens or camera, the shape and size of objects in the image are differe...
1.What is a wide angle lens?
A wide-angle lens is a lens with a relatively short focal length. Its main features are wide viewing angle and obvious perspective effect.
Wide-angle lenses are widely used in landscape photography, architectural photography, indoor photography, and when shooting need...
What is a distortion-free lens?
A distortion-free lens, as the name suggests, is a lens that does not have shape distortion (distortion) in the pictures captured by the lens. In the actual optical lens design process, distortion-free lenses are very difficult to achieve.
Currently, various types ...
1.What is a narrow band filter?
Filters are optical devices used to select the desired radiation band. Narrow band filters are a type of bandpass filter that allow light in a specific wavelength range to be transmitted with high brightness, while light in other wavelength ranges will be absorbed ...
What are the M8 and M12 lenses?
M8 and M12 refer to types of mount sizes used for small camera lenses.
An M12 lens, also known as an S-mount lens or a board lens, is a type of lens used in cameras and CCTV systems. The “M12” refers to the mount thread size, which is 12mm in diameter.
M12 lenses a...
1.Is a wide-angle lens suitable for portraits?
The answer is usually no, wide-angle lenses are generally not suitable for shooting portraits. A wide-angle lens, as the name suggests, has a larger field of view and can include more scenery in the shot, but it will also cause distortion and deforma...
Telecentric lens is a type of optical lens, also known as television lens, or a telephoto lens. Through special lens design, its focal length is relatively long, and the physical length of the lens is usually smaller than the focal length. The characteristic is that it can represent distant objec...
Industrial lenses are widely used in the industrial field and are one of the common lens types. Different types of industrial lenses can be selected according to different needs and application scenarios.
How to classify industrial lenses?
Industrial lenses can be divided into different types acc...
What is an industrial lens?
Industrial lenses, as the name suggests, are lenses designed specifically for industrial applications. They typically have characteristics such as high resolution, low distortion, low dispersion, and high durability, and are widely used in industrial fields.
Next, let&...
Machine vision lens is a lens designed for use in machine vision systems, also known as industrial camera lenses. Machine vision systems usually consist of industrial cameras, lenses, light sources, and image processing software.
They are used to automatically collect, process, and analyze images...
A large target area and large aperture fisheye lens refers to a fisheye lens with a large sensor size (such as full frame) and a large aperture value (such as f/2.8 or larger). It has a very large viewing angle and broad field of view, powerful functions and strong visual impact, and is suitable ...
