WebSep 11, 2024 · What is A F-theta Len. Galvanometer scanning systems are usually used in laser industrial processing, medical treatment, scientific research and measurement applications. After collimation or beam expansion, the laser beam is incident on the galvanometer lens in the X and Y directions, and then focused on the working surface … WebJan 17, 2024 · F-Theta lenses are commonly used in laser scanning systems that require a flat image plane and high resolution. By introducing a specific amount of barrel distortion in the lens, the image height of the F-Theta lens is proportional to the scanning angle. These diffraction limited lens systems can be engineered to produce the desired spot size ...

A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use a special mapping ("distortion"; for example: equisolid angle, see below), which gives images a characteristic convex non-rectilinear appearance. WebSpecial Optics Telecentric F-Theta UV Scanning lenses offer greater depth of field and smaller spot sizes when marking objects for laser material processing. Telecentric scanning lenses, by the very nature of their design, maintain a near normal incidence angle of the beam to the work piece. This ensures that position errors and image ...
