Case Study: Advanced 50mm Laser Beam Expander

Laser beam expanders are crucial optical devices used to increase the diameter of laser beams. They are essential in a range of fields, from precision manufacturing to advanced scientific research. By expanding the beam, these devices reduce divergence, allowing the laser to travel longer distances with less spread. This characteristic is vital for applications demanding high accuracy, such as laser cutting, welding, optical communication, and various types of laboratory experiments. 

Manufacturing Specifications

  • Wavelength: 1064 nm
  • Magnification: 5X
  • Entrance Pupil Diameter: 4 mm
  • Exit Pupil Diameter: 20 mm
  • Lens Dimensions: Φ26×50 mm

Optical Design Considerations

  • Pupil Diameters: The expander transitions from a 4 mm entrance pupil to a 20 mm exit pupil, designed to expand the beam while preserving its quality and minimizing wavefront distortion.
  • Wavelength Optimization: At 1064 nm, the choice of materials such as fused silica is critical. These materials ensure high transmission efficiency and minimal dispersion.
