View of the packaging
TVR2713DCIR M2315 is a high quality glass lens from Tokina of Japan, designed for cooperation with day/night cameras with 1/3" sensors. It can be used in most demanding applications. Aspherical optical lenses minimize the problem of losing focus when switching the camera from color to B/W mode with IR illumination, which is an important advantage in systems operating in variable lighting conditions.

Remarks IR correction
The lens enables the installer/user to set focal length from 2.7 mm to 12 mm. Adjustment of this parameter allows quick correction of viewing angle. In the case of cameras equipped with 1/3" image sensors, the angle can be changed within 98o do 24o (horizontally). The lens also has automatic iris (DC control).
An important advantage of the lens is the quality of moving components that are used for adjusting focal length, diaphragm, focus. They allow precise setting of the image under all conditions, which is an especially important feature for CCTV installers.
