Optimizing Machine Vision Lenses For Different Wavelengths

 Quality Magazine publishes an article covering consideration when Optimizing Machine Vision Lenses For Different Wavelengths.

"Lenses play a crucial role in the quality of the images produced by a machine vision system since they determine the sharpness of the image on the camera sensor. Lenses can influence image quality in a variety of ways:
  • Reduced light transmission due to lens surface reflections
  • Spherical, chromatic and defect aberrations preventing all rays of light from a single point on the object being focused to a single point on the image
  • Reduced light intensity towards the edge of the image
  • Spatial distortion of the image

By choosing the appropriate lens construction, all of these effects can be minimized. This article highlights some of the considerations when selecting a lens for your particular needs."
