Lens Focal Length Calculator

This focal length calculator is presented to help the user determine the basic parameters of his optical system, and to estimate required focal length. These are not final dimensions but they do provide a good idea of the layout. Please contact Universe to discuss your project and to obtain detailed dimensions and performance data.

Magnification = Imager Size / Object Size A Dimension = Object to Image Distance / Magnification + 1 B Dimension = A Dimension x Magnification Focal Length = A Dimension x B Dimension / Object to Image Distance
