Beam expander mirror
Used for CO2 laser system beam expander mirrors

 Laser beam expander has two main purposes: mirror the diameter of laser beams is extended for one; Another is to minimize laser beams divergence Angle. Therefore, it is used for long-distance lighting or projection, and focus on the system. A bunch of the beam by beam expander divergence Angle, and beam expander inverse ratio become changes. And without beam expander, compared to the beam of light after beam expander smaller can be focused on. Laser beam expander avaiable lens alignment is the magnification of beam diameter from laser beam, the output of beam width product for certain value, when approximately waist radius, the expanded x times corresponding divergence Angle for the original 1 / compressed x, compression divergence Angle is in fact the alignment of laser, flare size and divergence Angle product is optical not variables, divergence Angle decreases, and compression divergence Angle did not improve the beam quality, beam waist radius and the quality is the product of divergence Angle, compression divergence Angle at the same time will accompany waist radius of increases, the spot size increases, laser marker machine lens often peace games together to use.
