    Technical Manual (EN) v1.2.2 10.4 Choice of the right lens and lighting system 10.4.1 Find the correct lens Lenses are the starting point of the image processing signal path and shape the light information. The better the optics and the more time you've invested in this issue, the better the source material for the image processing.

  • Page 46 Technical Manual (EN) v1.2.2 http://www.matrix-vision.com/lens-calculator.html Because single lenses have strong aberrations, several lenses are used to compensate these errors. The wavelength of the light has a great influence on the image. For each wavelength, the image quality is good and/or is sharp in different spots.
  • Page 47 Technical Manual (EN) v1.2.2 Figure 6 Lens correction Zoom lenses ofter consist of 10 or more lenses. Real lenses have an entrance pupil and an exit pupil. The parameters b and g are calculated starting from these levels. If the distance of the levels equals h (also called main level), the total setting distance e is between object and image.
  • Page 48 Figure 7 Setting level The parameter h is usually not known. With the mvBlueGEMINI, h is usually very small. For this reason, the formula without h is used in test setup concepts. It should be possible to set every lens to infinity. In this case, the Distance between lens and image = focal length Therefore, each lens should be fixed in a different way.
