F-Theta Lens at 1064nm

  • Update:Jun 14, 2017
  • View:

F-theta lenses are used in laser scanners (laser markers) and the laser wavelengths may be 355/266/532/1064nm, 10.6um and other wavelengths. We can provide full range of f-theta lenses.

Product Introduction

Lenses used in combination with XY galvanometer scanner are called ƒ-theta lenses, plane field objectives or simple 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. A 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. The scan length specifications in this catalogue are based on mirror spacings of typical scan heads. For other scan systems the parameter “aperture stop” defines the distance of the geometrical center between the mirrors to the mechanical edge of the lens housing.
