355nm F-Theta Lens 103mm EFL 50x50mm | TSL-355-50-103Q-V2

Telecentric F-Theta Scan lens is a special type of lens system whereby the deflected off-axial laser beam can be perpendicularly focused to work piece as similar to the on-axial focusing beam. The advantage of the telecentric scan lens is that it is able to flatten the field curvature to the least distortion and yet offering superb spot quality throughout the scan field. For high powered laser and ultrafast laser source, we offer TSL-Q Series Telecentric F-Theta Scan Lens to minimize thermal lensing and focal shift.

F-theta lenses are commonly used in laser marking, welding, engraving and other applications, usually matched with galvanometer scanners.
For telecentric f-theta lenses, the outgoing light is always perpendicular to the working surface. The focused spot size remains uniform across the entire field of view, widely applied in precision cutting, marking and other applications.
Distortion ＜1%, Telecentricity ＜4°
