JENOPTIK JENar F-Theta Field Lens 160mm 1030-1080nm Fiber Laser Marking
This JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, features a 160 mm focal length – a mid-short model that balances working field and spot quality. Widely used in fiber laser marking, engraving, and fine cutting systems, the lens delivers exceptional performance with its bright blue anodized aluminum front ring and matte-black rear barrel.
Constructed with multi-element high-performance optical glass coated for 1030 nm - 1080 nm wavelengths, it provides low-distortion, high-uniformity focusing across a medium field. As a genuine German import with full traceability, it mounts directly to mainstream galvo scanners to form a complete scanning optical path.

Frequently Asked Questions
Q: What field size does F=160 mm suit?
A: Typical ~90×90 mm class for small-to-medium parts; confirm with the official datasheet.
Q: F=125, F=160 or F=255 – which one?
A: F=125 is finer with a smaller field; F=255 has a larger field with a coarser spot; F=160 is the versatile middle ground.
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: 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.
