Principle and function of laser field mirror

Principle and function of laser field mirror: the field mirror focuses the collimated laser beam on one point, improves the energy density of laser beam, uses the high energy of laser to process various materials, such as cutting, marking, welding, cleaning and surface treatment. At the same time, when the direction of the incident laser beam changes, the laser field mirror can still maintain the spot with the same relative size and energy density So that the laser beam can process the points of different material positions. The combination of field mirror and galvanometer which can change the direction of laser beam quickly and accurately can realize the high-speed and precise processing of materials.

Introduction of laser circular polarizer

Circular polarizer is a kind of reflector which can convert the linearly polarized laser beam into elliptical or circular polarized laser beam. Its function is similar to that of a quarter wave plate, but in the far-infrared band, there is no suitable birefringent crystal, so we can't make a transmission wave plate to change the polarization state of the far-infrared laser beam. The lens has a special film, which can change the incident light of 45 degree linear polarization of zero phase displacement into a circular polarization of 90 degree phase displacement.

Introduction of optical fiber laser spectroscope

Fiber optic laser splitter a splitter is an optical component that divides light into two parts. Spectroscope is a common optical component in laser and lighting systems. Laser spectroscope applications also include fluorescence applications, optical interferometry, life sciences or semiconductor instruments.

Laser those things big wave two - color laser new coming attack

Read "laser those things" before the article of friends, should have a lot of understanding of the advantages and disadvantages of laser light source. Now the laser light source is a "simplified" scheme. Although the blue laser hybrid fluorescent pink wheel reduces the cost, there are two problems with color. Why is that? Because the current blue laser has a slightly shorter wavelength of 2-6 nanometers, it is considered "purplish" by many consumers. After the blue laser + blue, green, red phosphor model to improve the problem, but the blue is not completely eliminated.

The principle of laser marking machine and system accessories interpretation

Principle and system of laser marking machine accessories reading: laser marking can be applied to all the pervious to light material marking, general optical path system: corrected by beam expander expanding beam divergence Angle, beam after us into indicator light, to the light beam deflection and scanning galvanometer system, the last through the F - THETA for scanning focusing mirror machining. Laser marking optical components mainly include beam expanding mirror and f-theta field mirror. The purpose of a beam expander is to enlarge the beam diameter and reduce the beam divergence Angle. F-Theta field mirror enables laser beam to focus uniformly.

What is the wavelength range of visible light

Visible light wavelength range: visible light is the part of the electromagnetic spectrum that can be perceived by the human eye. The average human eye can detect electromagnetic waves at wavelengths between 400 and 760nm, but some people can detect waves between 380 and 780nm.
