Sill Optics has extended its series of fused silica scan lenses for higher power fibre, fibre-delivered or slab lasers, which emit in the 1,030 to 1,090nm wavelength.
The new telecentric scan lens S4LFT082/328 has a focal length of 82mm and can image an 15mm laser beam with high quality. In combination with typical scan systems, a field size of approximately 20 x 20mm can be achieved. This scan lens includes the typical M85X1 thread for mounting and an easy to change cover glass.
The sophisticated ghost-free design, in combination with the special low absorption coating, pushes the boundary of standard glass scan lenses, and assures stable working conditions.
