Beam Expander Optics System

  The Beam Expander is any optical system designed to increase the diameter of a Laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.

   As the leading manufacturer and supplier in China, CNI is dedicated to offer best quality lasers , laser systems, High Power Laser, optical measuring equipment, Single Longitudinal Mode Laser, laser processing equipment, High Energy Laser,machine vision and the photoelectric detection equipment.

Features

• Low power loss
• Good output collimation
• Able to withstand laser power of more than 1000 W
• Adjustable divergence angle of 18 to 32 mrad with the variable beam expanders
  

Applications

• Precision laser machining: capable to provide a high power density focal spot.
• Laser range finder: capable to provide a highly collimated beam.
  
• Combining with a spatial filter, able to modify laser power distribution.
