Avantier specializes in custom F-theta lenses, ideal for laser systems in scanning, engraving, and cutting. Unlike ordinary lenses, an F-theta lens is an assembly of three or four pre-aligned lenses within a robust housing. It enables precise laser focusing on a flat surface, maintaining a consistent spot size across the scan field. The unique design makes it effective for laser applications.
