Optical Knowledge Sharing - Optical PolarizationPolarized light has three fundamental characteristics: wavelength, intensity, and polarization. The wavelength of light is easy to understand. For examp...

The day-night dual-pass filter, as an important optical component, is widely used in CCD and CMOS imaging systems, CCTV surveillance systems, and other fields. Its characteristic is that it can captur...

High damage threshold mirrors are crucial optical components designed to protect optical systems under high-power laser irradiation. They feature high reflectivity and a high damage threshold, effecti...

Common reflecting telescope systems are typically of the Newtonian or Cassegrain type. These telescopes use a concave mirror as the primary mirror to converge light and form an image, thereby avoiding...

The operating wavelength range of typical thermal imaging thermometers is in the mid to long-wave infrared, 2-14 µm (2000-14000 nm) or 7-14 µm (7000-14000 nm). The specific operating wavelength rang...

In a machine vision system, the lens acts as the eyes of the machine. Its primary function is to focus the image of the target object onto the photosensitive device of the image sensor (camera). All i...

Understand the imaging principle of aspherical lens, the characteristics and advantages compared with spherical lens.

Optical components are widely and critically used in machine vision. Machine vision, as an important branch of artificial intelligence, simulates the human visual system, using computers, cameras and ...
