Telecentric Lens

Lense for laser machineLenses used in combination with XY galvanometer scanners are called ƒ-theta lenses, plane field objectives or simply scan lenses. ƒ-theta lenses are used in various applications from industrial material processing, drilling, welding of synthetic material and cutting in addition to medical and biotechnology (confocal microscopy, ophthalmology) to science and research. The design and the quality of the optical components are playing a decisive role.

Standard lenses focus the laser beam on a spherical plain in contrast to an ideal flat or plane field. The use of ƒ-theta lenses provides a plane focusing surface and almost constant spot size over the entire XY image plane or scan field. The position of the spot on the image plane is directly proportional to the scan angle.

Advanced Focusing

The Autofocusing system is made up of a distance measurement module, stepping motor, stepping motor driver, control card and buttons. The distance measure module is used to detect the distance between galvo scanner head and the object down; Stepping motor is used to adjust the height of the galvo scanner; The buttons include Up, Down and Auto Focus. Control card controls the operation of the whole system.

Autofocus precision can achieve 0.1mm,measure range is 120mm-280mm, the system is equipped with alarm light and tone, when the object is not in the measurement, the control board indicator light is on and the buzzer alarm, then, through manual pressing button of moving up or down to move galvo scanner, which the object can be within a measuring range and the system will stop the alarm. The control board provides an alarm signal extension port, and the customer can receive the alarm signal externally according to the requirement. The automatic focusing system is increased the acceleration and deceleration process at the beginning and end of the moving process, which reduces shocking on the moment of starting or stopping. The moving speed can be set or change the moving by software.

3D Dynamic Focusing System

Laser Photonics OEM Kit with 3D Focusing System for laser cutting, laser marking laser engraving and laser cleaning
The 3D Dynamic Focusing System (3DDFS) removes the operator from the critical and time consuming step of focusing the laser allowing for 25% faster material processing with higher precision and repeatability.
3D Dynamic Focusing allows the laser machine to dynamically detect the shape and distance of the part, then focus the beam automatically and not rely on manual positioning, mechanical movement or operator programming. Without operator input and mechanical moving parts, the 3D Dynamic Focusing System increases reliability, stability, accurate positioning and ultra-fast processing speeds.
