F-Theta Optical Scan Lens

F-Theta Optical Scan LensStereolithography is an additive manufacturing process that is particularly suitable for the production of especially filigree components due to its high precision. In this process, the component is created by a laser curing of a liquid plastic layer by layer. A scan lens is required to focus the laser at specific positions resulting in curing at the corresponding location. To be able to manufacture large components the lens must have an extended scan field. So non-telecentric lenses are most suitable for such applications. The larger the free input beam diameter, the smaller the minimum achievable focus diameter and the more accurate the manufacturing is in the end. A focus diameter of less than 80 µm is ideal for enabling very fine structures.

The S4LFT1655/328 is very suitable for stereolithography applications in the infrared wavelength range. The lens has a scan field of 410 mm x 410 mm which enables the production of very large components. With a free input beam diameter of 20 mm focus sizes in the range of 64 to 72 µm — depending on the scan field position — are achievable. The S4LFT1655/328 is a fused silica lens and it is suitable for high-power laser applications. The low absorption of material and coating leads to slight heating of the lens during operation and thus to a stable process with a minimum thermal focus shift. If contamination or defects occur on the protective window it can be easily replaced by the customer.
