JENOPTIK JENar F-Theta Field Lens 170mm 1030-1080nm Fiber Laser Marking
This is a JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, with a 170 mm focal length — a mid-format all-round model widely used in fiber laser marking, engraving and cutting systems. The lens features a bright blue anodized aluminum front ring and a matte-black rear barrel, with multi-element high-performance optical glass coated for 1030 nm – 1080 nm, providing wide-field, low-distortion, high-uniformity scanning focus. F=170 mm balances field size and spot quality between F=160 and F=255, making it a common configuration for marking machine builders and end users. A genuine German import with full traceability, it mounts directly to mainstream galvo scanners to form a complete scanning optical path.
- Genuine German JENOPTIK: world-leading photonics company; the JENar series is an industry benchmark.
- Balanced Mainstream Focal: F=170 mm — a popular configuration balancing field and spot, between F=160 and F=255.
- Low Distortion, High Uniformity: field-wide focus consistency with no edge drift.
- Fiber Laser Optimized: 1030–1080 nm coated optics for mainstream fiber lasers.
- Durable Build: anodized aluminum housing for continuous workshop use.
- Easy Integration: standard mount, direct replacement.

- General Laser Marking: metal/non-metal identification, nameplates, serial numbers.
- Traceability Marking: QR codes, barcodes, anti-counterfeit codes.
- Laser Engraving: molds, crafts, wood and leather.
- Fiber Laser Cutting: mid-format thin-sheet cutting.
- Automotive / 3C Marking: auto parts and electronic components.
- Welding Focus: beam focusing in galvo welding systems.
- Q: What field size does F=170 mm cover? A: Typical ~95×95 mm class — between F=160 and F=255; confirm with the official datasheet.
- 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: F=170 mm vs F=160 mm / F=255 mm? A: F=160 is slightly smaller with a finer spot; F=255 offers a larger field (114×114) with a coarser spot; F=170 is the balanced middle ground.
- Q: How long do the coatings last? A: With normal use and cleaning, coating life matches the machine; avoid contamination and direct laser damage.
- Q: Warranty and after-sales? A: Genuine import with warranty per contract; technical support and lens inspection services are available.
- Q: Lead time? A: German import; typical 1 weeks (depends on stock and logistics); bulk orders can be pre-stocked.
