MTF Curve Analysis Guide
The MTF (Modulation Transfer Function) curve graph serves as a critical analytical tool for evaluating the optical performance of lenses. By quantifying the lens’s ability to preserve contrast across varying spatial frequencies, it visually illustrates key imaging characteristics such as re...Read more -
The application of filters across different spectral bands in the optical industry
Application of filters The application of filters across different spectral bands in the optical industry primarily leverages their wavelength selection capabilities, enabling specific functionalities by modulating the wavelength, intensity, and other optical properties. The following outlines th...Read more -
Which material is more suitable for use as a Lens shell: plastic or metal?
The appearance design of lenses plays a crucial role in modern optical devices, with plastic and metal being two predominant material choices. The distinctions between these two types are evident across various dimensions, including material properties, durability, weigh...Read more -
Focal length and Field of view of optical lenses
Focal length is a critical parameter that quantifies the degree of convergence or divergence of light rays in optical systems. This parameter plays a fundamental role in determining how an image is formed and the quality of that image. When parallel rays pass through a...Read more -
Application of SWIR in industrial inspection
Short-Wave Infrared (SWIR) constitutes a specifically engineered optical lens devised to capture short-wave infrared light that is not directly perceivable by the human eye. This band is customarily designated as light with wavelengths spanning from 0.9 to 1.7 microns. T...Read more -
The utilization of car lens
In the car camera, the lens undertakes the responsibility of focusing the light, projecting the object within the field of view onto the surface of the imaging medium, thereby forming an optical image. Generally, 70% of the optical parameters of the camera are determined...Read more -
The 2024 Security Expo in Beijing
China International Public Security Products Expo (hereinafter referred to as "Security Expo", English "Security China"), approved by the Ministry of Commerce of the People's Republic of China and sponsored as well as hosted by China Security Products Industry Associatio...Read more -
The interrelationship between Camera and Lens Resolution
Camera resolution refers to the number of pixels that a camera can capture and store in an image, typically measured in megapixels.To illustrate, 10,000 pixels correspond to 1 million individual points of light that together form the final image. A higher camera resolution results in greater det...Read more -

Speci...Read more -
Key parameter of the security camera lens-Aperture
The aperture of a lens, commonly known as the "diaphragm" or "iris", is the opening through which light enters the camera. The wider this opening is, the larger amount of light can reach the camera sensor, thereby influencing the exposure of the image. A wider aperture ...Read more -
