CS-mount varifocal lens for 1/3" sensors

The Computar Ganz TG3Z3510AFCS-IR is a varifocal CCTV lens built for CS-mount cameras using 1/3" format sensors. It provides a 3.5-10.5mm focal length range with an aperture of f/1.0 to 360 for low-light and bright-light surveillance. Manual zoom and focus controls allow adjustment without moving the camera. The lens features all-glass optics with an aspherical surface and a durable metal barrel.

Installers needing adjustable field of view

This lens suits installers who must vary the viewing angle on a fixed CS-mount camera positioned for 1/3" sensors. The IR-corrected design prevents focus shift between day and night operation. Buyers using cameras with larger sensor formats or bayonet mounts should look elsewhere. It is not intended for applications requiring motorised zoom or remote focal-length control.

Video auto iris with amplifier and locking setscrews

The integrated video auto iris with amplifier automates exposure control across changing light levels. Locking setscrews secure the chosen zoom and focus positions against vibration. These features reduce the need for manual readjustment after installation and help maintain consistent image quality in varying conditions.

Questions about this item

What camera mount and sensor size does the TG3Z3510AFCS-IR lens require?

The lens uses a CS-mount and is designed for 1/3" format sensors.

Will the video auto iris function work with an older CCTV camera that only supports DC auto iris?

No, this lens uses a video auto iris drive with amplifier and is not compatible with DC-iris camera ports.

How can I verify the IR correction is working after installing the lens?

Focus the camera at 0.3 m in daylight, then switch to infrared illumination; the image should stay sharp without refocusing.
