Linos Photonics GmbH & Co. KG has added two telecentric lenses to its line of f-Theta products. With the lenses, the laser beam is guided vertically over the scan field, providing a high depth of focus for marking objects in laser materials processing. For wavelengths of 532 and 1064 nm, a 100-mm focal length yields a scan field of 77 mm and spot sizes of 7 and 13 μm, respectively. The diameter of the entrance beam bundle is 15 mm, and deviation of the telecentricity is <0.9%.
