Introduction of Back Focus
TCM-5311 is a high class camera that has a
built-in back focus ring, by which it is
convenient to fine tune sensor position in
order to achieve the ideal distance of the
sensor from lens.
By rotating the back focus ring it is
possible to slide the sensor back or forth
inside the camera. The back focus ring is
shown on the image 1.
Once the back focus has been adjusted properly, the lens has been successfully
adapted to camera, and there is no need to re-adjust the back focus thereafter. All
the following adjustments are done on the lens itself by changing focal length (zoom)
and front focus, depending on the camera location and the distance to the
monitored object.
