JENOPTIK JENar F-Theta Field Lens 347mm Large Format 1030-1080nm Laser
This JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, features a 347 mm focal length—a large-format model designed for big-area laser marking, cutting, and engraving systems. The lens includes a bright blue anodized aluminum front ring and a matte-black rear barrel, with multi-element high-performance optical glass optimized for 1030 nm - 1080 nm wavelengths. It maintains low-distortion focus and uniform spots across a large scanning field.
The F=347 mm configuration is ideal for large-sheet marking, signage engraving, and big-workpiece identification, and is recommended for use with 14-25 mm aperture scanners. As a genuine German import with full traceability, it pairs effectively with SCANLAB large-aperture scanners for complete large-format scanning systems.
