depth of field for a given object and an optical system


Caution
Fill in all input cells.
Choose all parameters unit.
D, Dr and ds are strictly positive. Other parameters are algebric.
Positive direction is according the horizontal arrow in the bottom right of the scheme.

depth of field  for a given object and an optical system
fi : effective focal length D : clear aperture Dr : maximum diameter of the image spot s : distance from the primary principal plane to the object plane si : distance from the secondary principal plane to the image plane ds1 : depth of field calculated as the algebric distance from the ideal position of the object to one of the limit positions ds2 : depth of field calculated as the algebric distance from the ideal position of the object to the other limit position ds : total depth of field
