1064NM F-theta Scan Lens for YAG 205 / 330 laser marking machine
Detailed F-theta Scan Lens Product Description
F-theta lens YAG precision 1064nm /205*205/laser scanner lens
F-theta Scan Lens Quick Detail:
laser f-theta lens can be used for laser marking and laser engraving, work with marking head(laser scanner).
F-theta Scan Lens Specifications:
F-theta scanning lens is used in conjunction with XY galvanometer scanner and beam expander to form a two dimensions scanning system. The scan lens is optimized to provide a flat field image with diffraction-limited spot size in micron scale over the entire scan field. The image field height is almost directly proportional to the scan angle. Typically, the linearity f-theta distortion is kept less than 1% without software correction to ensure minimal distortion. High transmissive AR coating is coated onto the lens elements surface to ensure minimal power loss and hence increase the throughput. The scan lenses are designed with a industrial standard M85x1 mount threading to facilitate lens installation into laser machine. To accommodate different standard mount thread, mount adaptors are available for ease of conversion. Most of our products are RoHS compliant unless otherwise stated.
F-theta Scan Lens Product features:
long life
High work efficiency
F-theta Scan Lens Product introduction
F-theta scan lenses are commonly used in conjunction with galvanometer scanning mirrors in laser engraving, cutting, and marking systems. The reason it being named as F-theta is due to the radial image height equals to focal length of the lens multiplied by the angle of the chief ray makes in the object space. Hence, from the image height, the distortion of the image can be calculated at each field of interest. Typically the F-theta distortion of this lens is kept less than 1% so that it produces a precise spot on the flat field on image plane.
