The 19th China International Public Safety Expo will be held from October 25th to 28th, 2023. SECULENS will present the quality of globally renowned exhibitions to the world in Shenzhen. Showcasing the latest optical lens products and information to the world, committed to providing cus
What is IRCUT?The IR-CUT dual filter refers to the built-in set of filters in the camera lens group. When the infrared sensing point outside the lens detects changes in the intensity of light, the built-in IR-CUT automatic switching filter can automatically switch according to the intensity of exter
New Starlight lens ,The new starlight level interprets a new era, and F1.2 gives you a new experience. Full color at night, with the same effect day and night. The green coating design combines 4 pieces of glass and 2 pieces of plastic glass to provide clear images and ensure good results. This vide
For camera imaging, lens is an indispensable part. This article is to help you get familiar with the background, principle and other basic knowledge of the camera lens, master the application mode of the camera lens and select the type according to the needs.
Improve the camera's ability to process images by means of image conversion, etc., to achieve the best imaging effect. This is also the industrial development trend of intelligent cameras
What are the differences and differences between CS lens and C lens? These are the key points of this article. First, we will introduce what is C lens ?
Wide angle lens, also known as short focus lens, is a lens with a field angle greater than 60 °; For the zoom lens on the camera, the focal length is less than 25mm
ConceptIR lens is an infrared lens. It uses special optical glass materials, and uses the latest optical design methods to eliminate the focal plane offset of visible and infrared light. Therefore, light from visible light to infrared light can be imaged in the same focal plane, making images clear.
Fish eye lens is one of the most simple and effective methods to build panoramic vision. Its outstanding feature is that it can absorb all the information in a view angle of more than 180 degrees at one time, so as to achieve the effect of no blind area.
Differences between starlight lens, super starlight lens and black light lens
After the lens is installed, the lens needs to be adjusted. So, how to debug the lens? This article will give you a brief explanation
As the main part of light signal collection, optical lens has become an important component of new terminal electronic products such as AI recognition, projection video, smart home, virtual reality, laser projection, etc. For different electronic devices, the optical lenses carried by them also have slight differences in morphology and technical standards.
When video surveillance pays more and more attention to HD, people pay more attention to the monitoring system from the whole to the details. For example, users no longer only pay attention to the surveillance camera, but whether the surveillance lens and chip processor support low illumination, wide dynamic and other functions. If you want to monitor the image more perfectly, you need to start with the "head". Understand the monitoring imaging effect through the monitoring lens.
It mainly has three application functions:The first is the positioning function, which can automatically determine the location of interested objects and products, and output the location information through a certain communication protocol. This function is mostly used for full-automatic assembly a
Lens is the eye of surveillance camera. Correct selection of lens and good installation and adjustment are the first step of clear imaging. At present, 1 / 3 "lens is the mainstream of application, the sales volume of automatic aperture lens is the largest, and zoom lens is the development trend of application.
