What is day and night confocal? As an optical technology, day and night confocal is mainly used to ensure that the lens maintains sharp focus under different lighting conditions (i.e., day and night). This technology is mainly suitable for scenarios that need to operate continuously under all-weather conditions, such as security monitoring,...
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 deformation...
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 objects...
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 according to different classification standards. Common...
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's take a closer look at the application fields...
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 to automatically judge the quality of...
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,...
Fixed focus lenses are favored by many photographers due to their high aperture, high image quality, and portability. The fixed focus lens has a fixed focal length, and its design focuses more on optical performance within a specific focal range, resulting in better image quality. So, how do I use...
