Avantier excels in delivering laser lenses of superior performance, spanning wavelengths from ultraviolet to visible, near-infrared, and even extending to long-wave infrared; a wide selection of lens substrates are offered as well

Laser lenses are integral optical components employed within laser-based devices for a multitude of laser applications. These applications encompass, among others, laser illumination, laser collimation, laser scanning, laser dimensioning, material processing, laser welding, laser cutting, laser tracking, line/pattern generation, and more. A range of laser lens types exist, encompassing spherical lenses, aspherical lenses, cylindrical lenses, Axicon lenses, and Powell lenses.

• Laser collimating lens: Turns the diverging output of a laser source into a collimated beam. Focal length depends on the laser’s divergence angle (FWHM) and the desired beam diameter.
  
  
• Laser focusing lens: Concentrates a laser beam into a small focal spot. Focal length depends on the initial beam size, desired spot size, and required depth of focus.
  
  
• Powell lens: Converts a collimated Gaussian beam into a straight line with uniform intensity along its length, unlike the Gaussian-profile line a standard cylindrical lens produces.
  
  
• Cylindrical lens: Spreads a collimated beam into a line with a Gaussian intensity profile, so it serves as the baseline for comparison with the Powell lens.
  
  
• Axicon lens: Uses a conical surface to transform a collimated beam into a ring-shaped focal spot or line, with the axicon angle tuned to the application.
  
  

Customization is available for laser lenses to meet specific system requirements. Avantier offers custom collimating, focusing, Powell, cylindrical, and axicon lenses tailored to individual needs. This includes the ability to select substrate materials, coatings, and surface quality based on the laser type, wavelength, and power level.

Whether it’s a CO2 laser, high-power fiber laser, solid-state laser, or laser diode, Avantier provides a wide range of substrate options including BK7, H-K9L, Sapphire, UV-grade fused silica, IR-grade fused silica, calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), zinc sulfide (ZnS), gallium arsenide (GaAs), germanium (Ge), and silicon (Si), with coatings matched to your operating wavelength and damage threshold requirements.
