Scanning field lens, also called field lens or F-Theta field lens, is an optical element widely used in scanning systems. It is a lens that generally works near the focal plane of the objective lens and can effectively reduce the size of the detector. It is usually used to focus the collimated laser beam on a point, increase the energy density of the laser beam, and use the high energy of the laser to perform various processing on the material. When the direction of the incident laser beam changes, the field lens can still maintain a spot with constant relative size and energy density, so that the laser beam can process points at different material positions. The field lens is combined with a galvanometer that quickly and accurately changes the direction of the laser beam to achieve high-speed and precise processing and treatment of materials.

Product Introduction
As a professional lens system, the scanning field lens aims to form a uniformly sized focused spot of the laser beam in the entire marking plane to solve the off-axis deflection phenomenon of the laser beam after passing through the focusing lens system in the marking system. It is one of the most important accessories for laser marking machines. F-theta lenses are mainly used in laser marking machines for industrial applications. In the absence of deformation, the position of the focus point depends on the focal length of the lens and the tangent of the deflection angle. The position of the focus point only depends on the focal length and the deflection angle, which simplifies the calculation method of focus positioning.
