How to choose a lens and the focal length calculation formula

Height focal length =ccd height*shooting distance/ccd height+target height

Matching problems:
  • Problems with the interface of the lens or camera. Generally, there are C and CS interfaces. You can ask the supplier if there is an adapter ring.
  • When matching a lens with a camera, you must pay attention to whether the lens itself can support the camera's SENSOR SIZE. For example, if the lens specification is to accommodate 1/2" or 1/3" sensors, if it is paired with a 1" camera SENSOR, it will cause the problem of blackened edge images.
  • Whether the working distance meets the requirements, if there is a limit on the working distance, please refer to the lens specifications. This factor involves the installation location of the on-site machine.
