Powell lens and ordinary linear laser lens
2023-09-01
Powell Lens and ordinary linear laser lens have the following main differences:
Structure and design: Powell lens is an optical ruling prism, which can optimize the laser beam to form a straight line with uniform light density, good stability and linearity. The ordinary linear laser lens is usually a cylindrical lens, which can divide the laser beam into a line, but the quality and stability of the line may not be as good as Powell lens.
Laser beam shaping effect: Powell lens can eliminate the central hot spot and fade edge distribution of Gaussian beam, achieving better laser beam shaping effect. The ordinary linear laser lens may not be as good as Powell lens in terms of shaping effect.
Application occasions: Powell lens is suitable for applications where high precision and good beam quality are required, such as precision marking and cutting. The ordinary linear laser lens is suitable for occasions where requirements are not high and the price is relatively low.
In summary, Powell Lens and ordinary linear laser lens have obvious differences in structure, design and laser beam shaping effect. Choosing the right lens according to specific application occasions and requirements is key.
