Telecentric Scan Lens

 

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 peice 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 F-theta Scan Lens to minimize thermal lensing and focal shift.

Remark: The spot size is simulation result, it does not reflect the actual spot size on workpiece as the simulation does not consider the material properties and how the laser being absorbed during machining.
