The calculator is easy to use. The user selects one of the available MATRIX VISION sensors from the list. The calculator then plugs in the features of the sensor into the calculation. The user then enters the distance of the object (in mm) as well as the size of the object (mm), either height or width, and starts the calculation. The calculator then displays the focal length required for the chosen sensor size.
The lens size must be greater than the sensor size. Thus, if the sensor is 1/2", then the lens can be a 1/2", 2/3" or 1". If the lens is less than 4 mm, you may wish to look at CS Mount lenses with the appropriate adapter from MATRIX VISION. Consider a vari-focal lens of say 4-12 mm if the calculated lens falls into this range - giving flexibility on distance to the object and Field of View.
Digital Network Vision would then recommend and source the appropriate lens for your application. Click on link below.
