Basic concepts and parameters of optical filters 1. Filter differentiation by spectral band: Filters are divided into ultraviolet filters, visible filters, near-infrared filters, infrared filters,

optical coating are ubiquitous in our daily lives, from precision and optical equipment, display devices to optical thin film applications in daily life; For example,

Generally speaking, narrow bandwidths can only pass through light with a peak wavelength of a few nanometers, which is much less than ordinary filters; Narrowband

An optical prism is a piece of glass or other transparent material cut at a precise angle and plane in optical devices, which can be

Differences between Aspheric and Spherical Lenses A spherical lens refers to a constant curvature from the center to the edge of the lens, while an

The curvature radius of optical lenses is not well understood by many of you here. Lens is an object that can amplify and reduce the

Biochemical filters are the central components of biomedical instruments. In order to ensure the accuracy of diagnosis and analysis, biochemical filters require high narrowband bandwidth

The function of Glued Lens is to eliminate chromatic aberration, requiring at least two materials, such as two types of glass (common lenses) or resin

Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effectiveness of algorithms. Optical lenses

Characteristics of Laser and laser optics Compared with ordinary light, laser has the following characteristics: 1. High brightness 2. Good monochromaticity and directionality 3. Good
