JENOPTIK JENar F-Theta Field Lens 125mm 1030-1080nm Fiber Laser Marking

This is a JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, with a 125 mm focal length — a short-focal, high-precision model for fiber laser marking and engraving systems. The lens features 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.

Within a small scanning field it delivers a very small focused spot and high energy density, ideal for fine text and precision graphics. A genuine German import with full traceability, it mounts directly to mainstream galvo scanners to form a complete scanning optical path.

Product Highlights
  • Genuine German JENOPTIK: World-leading optics company; proven JENar series quality.
  • Short-Focal Precision: F=125 mm, small spot and high energy density for fine marks.
  • Fiber Laser Optimized: 1030-1080 nm coated optics for mainstream fiber lasers.
  • Low Distortion: F-Theta design keeps field-wide focus consistency and linearity.
  • Durable Build: Anodized aluminum housing with optical glass elements.
  • Easy Integration: Standard mount, direct replacement.

Frequently Asked Questions
  • Q: How to choose between F=125 mm and F=100 mm?
    A: Both are short-focal precision models; F=125 offers a slightly larger field with a marginally larger spot. For parts up to ~60-80 mm, either works — choose by field requirement.
  • Q: Which lasers and scanners does it pair with?
    A: Suits 1030-1080 nm fiber lasers and SCANLAB basiCube / intelliSCAN class 10-14 mm scanners.
  • Q: How small can it mark?
    A: The short focal length produces a fine spot, supporting fine text and high-density QR marking; final resolution also depends on laser beam quality.
  • Q: Mounting standard?
    A: Standard thread/flange mount; most equivalent lenses are interchangeable. Send your barrel spec and we will confirm.
  • Q: Warranty and after-sales?
    A: Genuine import with warranty per contract; technical support and lens inspection services available.
  • Q: Lead time?
    A: German import; typical 2-4 weeks (depends on stock and logistics); bulk orders can be pre-stocked.
