Telecentric camera objective / machine vision

Features
1064 nm Design Wavelength for Nd:YAG Laser Systems
Flat Field at the Image Plane
Large 70 mm x 70 mm Scan Field
F-Theta Distortion (Deviation from a Flat Image Plane) of <0.1%
Air-Spaced Design
Thorlabs' F-Theta lens features an air-spaced, 3 element design with a 100 mm focal length. The elements are coated with a high efficiency AR coating for a 1064 nm Nd:YAG laser and for a visible alignment laser (see the Specs table to the right). The lens has a standard M85 x 1 thread for use with most commercial laser marking systems as well as Ø75 mm protective glass window that can be easily changed.

F-theta lenses are the standard lenses for galvo-scanner-based laser marking, engraving, and cutting systems. The diffraction-limited, multiple-element, air-spaced lens design is optimized for a flat field in the image plane and a low f-theta distortion. In an f-theta lens, the output beam displacement is equal to f*θ, where θ is the angle of incidence of the input beam (see the diagram below). Thus, the input beam angular velocity is directly proportional to the output beam angular velocity, allowing the scanning mirrors to run at a constant angular velocity, greatly simplifying control electronics.
