英文摘要	F-Theta lens is an important unit for selective laser melting (SLM) manufacture. The dual wavelength f-Theta lens has not been used in SLM manufacture. Here, we present the design of the f-Theta lens which satisfies SLM manufacture with coaxial 532 nm and 1030 nm∼1080 nm laser beams. It is composed of three pieces of spherical lenses. The focal spots for 532 nm laser and 1030 nm∼1080 nm laser are smaller than 35 μm and 70 μm, respectively. The results meet the demands of high precision SLM. The chromatic aberration could cause separation between two laser focal spots in the scanning plane, so chromatic aberration correction is very important to our design. The lateral color of the designed f-Theta lens is less than 11 μm within the scan area of 150 mm x 150 mm, which meet the application requirements of dual wavelength selective laser melting. © 2016 SPIE.
