Liquid lenses for CT MAX cameras
Focusing is electrical: the optical power of the liquid element changes on command from the camera, with no moving mechanical parts. 1.1″ format, C-mount, 0.1 m minimum object distance, fixed iris. Power and control run over a four-wire lead (DC, GND, Lens_TX, Lens_RX) from the CT MAX camera.

How to choose
The refocusing range is set by the camera, not the lens: the liquid element shifts focus between the 0.1 m minimum object distance and infinity. Focal length is chosen as for any fixed-focal lens — from working distance and field width; a 1.1″ sensor is 14.1 mm wide, so a 200 mm field at 300 mm needs ≈ 21 mm. Check the FOV table in the datasheet for exact figures.
