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.

Product Highlights
• Genuine German JENOPTIK: World-leading optics company with proven large-format JENar quality.
• Large Format, High Efficiency: 347 mm focal length significantly enlarges the scanning field.
• Low Distortion Design: 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 production.
• System Matching: Can be supplied with large-aperture scanners (intelliSCAN III 20/25 class) as a set.

Frequently Asked Questions
Q: What is the exact field of F=347 mm?
A: Typical ~180×180 mm class; exact values per the official datasheet. Large formats mean a relatively larger spot—best for large-part marking.
Q: What scanner aperture is required?
A: We recommend 14-25 mm aperture scanners (e.g., SCANLAB intelliSCAN III 20/25 class) to maintain spot quality over large fields.
Q: Can it mark fine small text?
A: Large-format lenses produce a larger focused spot; for fine marks choose short-focal models (F=100/125/160). This model prioritizes large-area efficiency.
Q: Which lasers does it suit?
A: Suits 1030-1080 nm fiber lasers; UV or CO2 lasers require the corresponding wavelength version of the lens.
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 1-2 weeks (depends on stock and logistics); bulk orders can be pre-stocked.
