A pinhole lens is a small and lightweight lens that is widely used in various industrial scenarios, such as industrial monitoring scenarios. So, what are the advantages of using pinhole lenses in industrial monitoring? Advantage 1: Concealment and security Pinhole lenses, with their compact design and extremely small aperture, can be easily hidden in various devices or environments, making them difficult to detect. This concealment makes them ideal for monitoring scenarios requiring high security, such as inside factories and around critical facilities. Advantage 2: Compactness and flexibility The pinhole lens is designed to be small and compact, and its installation location can be more flexible and diverse without being restricted by space, and can adapt to monitoring needs in various complex environments. This allows them to be installed in industrial equipment with limited space or difficult access to achieve monitoring goals. The pinhole lens is designed to be small and compact A...

A fisheye lens is an ultra-wide-angle lens with an extreme viewing angle, typically exceeding 180 degrees, and exhibiting strong barrel distortion. Due to its unique perspective, fisheye lenses can often create striking images in landscape photography, making them suitable for certain types of landscape photography. In general, fisheye lenses are suitable for shooting the following types of scenery and can show their unique charm: 1. Unique city landscape Fisheye lenses are often used to shoot urban buildings or street scenes. Their wide viewing angle can incorporate elements such as the city's skyline, skyscrapers, streets, and pedestrians into the picture, creating a shocking effect. The fisheye distortion effect can make the lines of the city more distorted and exaggerated, showing the prosperity and modernity of the city and giving people a unique visual experience. For example, using a fisheye lens to capture uniquely shaped buildings can better capture their distinctive curv...

Optical lenses are the core components of optical imaging systems. Their imaging quality and performance directly affect the performance of the imaging system in practical applications. Therefore, it is very necessary to test the various performance indicators of optical lenses. By testing the performance indicators of optical lenses such as resolution, contrast, distortion, dispersion, and focal stability, we can fully understand the imaging characteristics of the lens and provide data support for lens design optimization, production, manufacturing, and subsequent maintenance. Ⅰ . The main contents of optical lens inspection The inspection of optical lenses covers many aspects, mainly to comprehensively evaluate the imaging quality and mechanical performance of the lens. Its main contents include the following directions: 1. Optical performance testing Resolution testing. Resolution is a measure of the lens's ability to distinguish object details and is the primary indicator of l...

Fisheye lens , as an extreme wide-angle lens, has unique imaging characteristics, showing obvious "barrel distortion". This lens can present daily scenes or objects in an exaggerated and humorous way, as if bringing us into a "distorted" world like a funhouse mirror, adding endless fun and creativity to photography. 1.The c haracteristics   of fisheye lenses In the art of photography, to capture a unique distortion effect, you can choose to use a fisheye lens directly. Although it is expensive, it can bring you the ultimate shooting experience. As an ultra-wide-angle lens, the core features of a fisheye lens are its extremely short focal length and ultra-large field of view, which allows it to capture extremely distorted images. Let's take a look at the main features of a fisheye lens. Ultra-wide-angle field of view The field of view of a fisheye lens is much wider than that of an ordinary wide-angle lens, usually 180°~220°, and some are even higher. This ultra-...

The M12 lens is a miniaturized camera lens. Its important features are compactness, lightness, and easy installation and replacement. It is usually used in small devices or scenarios with limited space, and is often used in some surveillance cameras or small cameras. M12 lenses are widely used in small cameras, providing high-definition images and videos to meet the shooting needs of different scenes. Their specific applications include but are not limited to the following aspects: 1. Small space surveillance cameras The M12 lens is suitable for installation in small spaces, such as indoor surveillance cameras, smart home cameras, etc. It can provide clear video images for monitoring the security of small places such as homes, offices, and stores. 2. Car cameras In cars and other vehicles, M12 lenses can be used in small onboard camera systems to record video and images while the vehicle is in motion. For example, they can be used in dashcams and reversing cameras. They can help recor...
