Lenses 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.

Our built in camera makes it possible to perform automatic focusing without the use of any external devices. This is possible even when targets may not be placed at the exact same focal length from the laser and eliminating the need for external tooling. Additional production costs can be kept to a minimum while increasing efficiency and throughput.
*The built-in camera is used to monitor the focal distance using the laser pointer. Automatic focusing is performed by calculating the focal distance from the pointer position. This measurement may not be possible in some cases due to the material, shape, and surface of the workplace.
