The photonics group from Jenoptik developed a new F-theta lens that has been specially developed for the high-precision creation of complex structures in 3D printing, particularly in selective laser sintering (SLS). The new lens, JENar™-APTAline™-639-1030...1080-580-AL, was presented for the first time at the Laser World of Photonics trade fair in Munich in June.
The new lens was designed to meet the unique requirements of selective laser sintering (SLS). The SLS process requires a high degree of precision and accuracy. A plastic or metal powder is applied layer by layer and the powder particles are melted with a laser at the desired points to form a solid structure. The F-theta lens plays a key role here, as it focuses the laser beam onto the printing surface over the entire working area with limited diffraction and high precision.
The new F-Theta lens JENarTM-APTAlineTM-639-1030...1080-580-AL is designed for wavelengths of 1030 ... 1080 nm and has a focal length of 639 mm. It has a scan field of 410 mm x 410 mm and offers excellent spot homogeneity across the entire field thanks to its optimized optical design.
