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."
