AMAOE Precision Titanium Alloy Tweezers Bent Straight Tip

Tweezers (niè zi) are a tool used to pick up bulk medicines, metal particles, hair, fine thorns and other small things. It can also be used for mobile phone maintenance, using it to hold wires, components and integrated circuit pins.
Different occasions require different tweezers. Generally, a pair of straight, flat, and elbow tweezers should be prepared. The tweezers used in chemistry should not be heated, and should not be used to hold acidic chemicals. They must be kept clean after use.
March 04, 2014 Scientists in Spain and Australia have developed the world's smallest tweezers, which can pick up a single virus or molecule. 1. Stainless steel tweezers 2. Anti-static plastic tweezers 3. Bamboo tweezers 4. Medical tweezers 5. Purification tweezers 6. Wafer tweezers 7. Anti-static interchangeable head tweezers 8. Stainless steel anti-static tweezers. It is made of carbon fiber mixed with special plastics, with good elasticity, durability, no ash, acid and alkali resistance, and high temperature resistance, which can avoid the pollution of traditional anti-static tweezers due to carbon black, and is suitable for the production of precision electronic components such as semiconductors and ICs. use, and its special use. Anti-static tweezers are made of special conductive plastic materials, with good elasticity, lightness in use and static discharge characteristics, suitable for the processing and installation of static-sensitive components. Surface resistance: 1000KΩ—100000MΩ.
Anti-static tweezers are suitable for the production of precision electronic components, semiconductor and computer magnetic heads and other industries. Introduction
As the name suggests, optical tweezers are tweezers formed with light, which are based on the principle of light radiation pressure.
principle
The idea of ​​light radiation pressure originated from the era of Kepler and Newton. At that time, the theory believed that light was a kind of particle. According to the principles of Newtonian mechanics, a moving particle beam would generate pressure. In astronomy, the tail of a comet always faces away from the sun is light. A typical example with radiation pressure. However, the existence of light pressure and Maxwell's theoretical predictions of radiation pressure were not experimentally demonstrated in the laboratory until the early 20th century.
history
The study of light pressure was revolutionized in the 1960s when lasers emerged as coherent light sources with extremely high brightness. In the early 1970s, people began to conduct comprehensive and in-depth research on laser radiation pressure, especially theoretical discussions and experimental observations on the nature and mechanism of radiation pressure on atoms under different conditions, so as to develop the laser deflection of beams. Laser cooling, photon and fountain and other experimental technologies, and at the same time use light pressure for trapping, particle manipulation and other research. It is precisely because of the pioneering research in laser cooling that the famous Chinese scientist, Professor Steven Chu of Stanford University, won the 1997 Nobel Prize in Physics together with two others.
We know that light sources have both thermal and radiation effects. For ordinary light sources, the pressure generated by thermal effects is several orders of magnitude larger than the radiation pressure generated by pure momentum exchange, so it is difficult to obtain sufficient radiation pressure. The emergence of lasers changed this situation, so that the radiation pressure of light can be obtained Fully embodied. At the same time, the cross-sectional distribution of the laser beam has a simple and definite mathematical expression, which is convenient for theoretical processing and makes the research of optical trap and optical suspension possible. Laser tweezers use the mechanical effect of momentum transfer between laser and matter to form a three-dimensional optical potential well.
