Lens Field Calculator

///Lens Field Calculator

Our lens field calculator is a web-based tool to calculate video camera lens fields of view. Based upon Snell’s law, this tool measures the resulting field of view based on an ideal lens. We offer this tool as a complimentary service to the subsea community.

Please keep in mind that wide angle lenses tend to vary significantly from specs due to lens distortion.
