Build a large-sensor measurement layout

A larger sensor can provide a useful measurement field, but only when the lens image circle and magnification suit the camera. Check the optical and mechanical constraints together. The field, working distance and lens body may have a greater effect on the layout than the format label alone.

  • Use the camera active sensor dimensions and the model image-circle rating to confirm coverage; the optical-format designation is not a literal chip width.
  • Calculate the object field from the active sensor and magnification, and compare it with the complete part envelope and required image detail.
  • Review the lens mount, mass, body size and working distance before designing brackets or lighting. Confirm the printed distortion and telecentricity limits for the chosen model.
