Beam homogenizers are used to obtain a uniform energy distribution in the illuminated field ("flat-top" or "top-hat"). Refractive beam homogenizers are appropriate for coherent and incoherent radiation independent of the wavelength.

Key features

• high power laser applications
  
• high efficiency
  
• spectral wavelength 193nm-5um
  
• Anti-reflection coating optional
  
• Various working distances and flat-top sizes
  
• flat-top types: Line-Flat-Top-Generators, Square-Flat-Top-Generators, Spot-Generators, laser sheet
  
• applications: medical applications, laser material processing, laser ablation, imaging, laser pumping, mask or reticle illumination, metrology, fluorescence excitation…
