Focal length calculator

Goyo Optical has launched its focal length calculator. Available on, this web tool allows users to calculate, quickly and easily, the most effective lens focal length for their system, ensuring the aspect ratio of the sensor size equally pairs with the aspect ratio of the object being imaged – preventing image clipping.

Based on the sensor size, working distance and field of view entered into the tool, the calculator computes the effective focal length while also providing the best lens options. Companies can now take the guess work out of finding the most optimal lens for their application.
