Mounting thin lenses to their mechanical interfaces comprises imperfections to the initially designed optical paths due to manufacturing and assembly tolerances.
This sheet provides qualitative information about the phenomena because derivation of the shifts and tilts of the image as a result of the lens and/or object movement is extensive and non-transparent. Therefore a Matlab® code is provided with the necessary computations for lens x, y, and object , such that they can be combined at will.
= focal length (average)
= refractive index of lens (medium air/vacuum: )
= incoming radius, outgoing radius
= object distance, image distance
Focus distance , object and image distance:
Due to manufacturing also the incoming and outgoing radii of the lens can differ. Consequently the focus distance is affected:
