As a specially designed lens, the IR corrected  lens can monitor road traffic conditions in all weather and all directions in road monitoring, providing important data support for traffic management agencies. So, what are the specific applications of IR corrected  lenses in vehicle identification? IR corrected  lenses have a large aperture and high sensitivity, and the focal length is usually adjustable. They are suitable for shooting during the day and at night, and can provide clear images under different lighting conditions. In vehicle recognition, IR corrected  lenses usually have the following applications: 1. Vehicle tracking and identification The high sensitivity and clear image quality of the IR corrected  lens can track and identify vehicles on the road and monitor information such as the number, type and speed of vehicles. Visibility is low at night, and traditional lense s may not be able to clearly capture images of vehicles. However, the IR correc...

Pathology and medical diagnosis In the medical field, high-power microscope lenses are used for pathology research, disease diagnosis, and histological analysis. Doctors can use these lenses to observe tissue samples, cell smears, and blood samples to detect diseases, diagnose disease types, and monitor disease progression. For example, in cancer diagnosis, doctors can use high-power microscope lenses to observe abnormal cell morphology in tissue samples. High-p...

Industrial lenses are lenses specifically used for imaging applications in the industrial field. They have certain specific characteristics that can meet the requirements of the industrial field for imaging quality and accuracy, and are therefore widely used in industrial production and manufacturing processes. In this article, we will learn about the imaging characteristics of industrial lenses. High resolution and clarity Industrial lenses have high resolution and clarity, which can capture small details and precise images, ensuring that the imaging quality meets the needs of industrial applications. This is very important for scenes that require precise detection and measurement in industrial applications, such as in the field of quality inspection and measurement. Good optical properties The design and manufacture of industrial lenses usually take into account the stability and consistency of optical performance. For example, it usually designs and optimizes the optical system sui...

CCTV  lenses have a wide range of applications and can be found in various indoor or outdoor environments. Different usage environments have different requirements for CCTV  lenses. Let’s take a look at them in detail below. 1. Indoor environment In indoor environments, CCTV  lenses usually need to have high definition and a wide viewing angle coverage to ensure that a wider area and details can be monitored. In addition, for indoor environments, it may also be necessary to consider aspects such as the appearance design of the lens so that it can better integrate into the interior decoration. 2. Outdoor e nvironment In outdoor environments, CCTV  lenses need to be waterproof, dustproof, shockproof, and riot-proof to maintain normal operation under various adverse weather and environmental conditions. At the same time, the light in outdoor environments varies greatly, so CCTV  lenses need to have good adaptability and be able to maintain clear monitoring images ...

Industrial endoscope is a common inspection equipment used in the industrial field. The lens is an important part of it. It is mainly used for inspection and observation in narrow or difficult-to-reach spaces. Common application scenarios of industrial endoscope lenses Industrial endoscope lenses have a wide range of applications, and its common application scenarios include but are not limited to the following aspects: Steel and metal processing industry During steel and metal processing, industrial endoscope lenses can be used to inspect cracks, corrosion and other damage problems inside equipment such as pipes, containers, and pipe connections. They can also be used to inspect welded joints, welds, and metal components. Industrial endoscope lenses used in the steel industry Automotive repair and manufacturing In the automotive repair and manufacturing industries, industrial endoscope lenses can be used to inspect parts inside car engines and transmission systems, such as cylinders,...

A bird shooting lens , or bird watching lens, is a lens specially used for wildlife photography. Long focal length and large aperture are its important features. As the name suggests, bird shooting lenses are mainly used to shoot long-distance animals, especially birds in flight, and can capture the details and movements of birds flying in the air. How to use bird-shooting lenses in wildlife photography Bird shooting lenses have unique application value in wildlife photography. Let’s take a look at their specific applications. 1. Photographing birds in flight The bird shooting lens has a long focal length and a large aperture, and can focus quickly when shooting. It is very suitable for shooting birds in flight, and can capture their graceful postures and dynamics, such as flying, hunting, migration and other scenes. They are very suitable for shooting birds in flight and can capture their graceful postures and movements, such as flying, hunting, migration, etc. The high-speed continuo...

To judge whether the imaging quality of an optical lens is good, some testing standards are needed, such as testing the focal length, field of view, resolution, etc. of the lens. These are all conventional indicators. There are also some key indicators, such as MTF, distortion, etc. 1. MTF MTF, or optical modulation transfer function, can quantify aspects of an image, such as details, contrast, and clarity. It is one of the indicators for comprehensively evaluating the imaging quality of a lens. In the MTF two-dimensional coordinate curve, the Y axis is usually the value (0~1), and the X axis is the spatial frequency (lp/mm), that is, the number of "line pairs". Low frequency is used to evaluate the contrast of the image after imaging, and high frequency is used to examine the clarity and resolution of the lens, that is, the ability to distinguish details. For example, for photographic lenses, 10lp/mm is usually used to examine the contrast effect, and the MTF value is gener...
