    Abstract: A system, method, and device for measuring camber in a film is disclosed. The system generally includes: a flat surface with a longitudinal axis, at least three sensors spaced apart along the longitudinal axis, and a computing device operatively connected to each sensor. When the film is positioned in relationship to the sensors, the computing device computes the camber of the film. The flat surface may be a table with a film holder. At least one of the sensors may be a LED sensor. The computing device may have an output means, such as a monitor, a printer, or both. The computing device defines a straight line between the first and third sensor based on the position of the film, and the camber is a deviation of the film, measured by the second sensor, from the straight line.
