This laser illuminator is high performance integrated with high quality fiber-coupled laser diode and excellent optics design, and outstanding circuit control with high efficiency. It has big beam angle zooming, which can match the field view angle of cameras. It also has friendly interfaces such as operating voltage, communication protocol and installation schematic. It can be widely used in high-speed dome, PTZ camera and traffic monitoring.

This illuminator is compatible with major lens and cameras, integrated with the protocols such as Pelco D and QLINK. It is easy for users to implement the illuminator. Simultaneously, Position can be preset via serial port, users can call the instruction to operate conveniently in use.

As the optic head is separated from diode and circuit, it is very easy to collimate the laser lens and camera lens, which can make the tunable rack compact.
