JENOPTIK JENar F-Theta Field Lens 100mm 1030-1080nm Fiber Laser Marking

JENOPTIK JENar F-Theta Field Lens 100mm 1030-1080nm Fiber Laser Marking

This is a JENar series F-Theta field lens (laser scanning focusing lens) from JENOPTIK, Germany, with a 100 mm focal length, designed for fiber laser marking, engraving and precision cutting systems. The lens features the classic structure of a bright blue anodized aluminum front ring and a matte-black rear barrel, with multi-element high-performance optical glass inside, optimized for the 1030 nm – 1080 nm wavelength range. The short 100 mm focal length delivers a smaller focused spot and higher energy density, ideal for small parts and high-precision laser processing. A genuine German import with full traceability, it mounts directly to mainstream galvo scanners to form a complete scanning optical path.

FAQ

1. Q: Which lasers is this lens compatible with? A: It suits 1030–1080 nm fiber lasers and related solid-state lasers, including mainstream brands.
2. Q: What field size does F=100 mm cover? A: Shorter focal length means a smaller field and finer spot; F=100 suits small formats (typical ~60×60 mm) for high-precision work. Confirm with the official datasheet.
3. Q: Can it work with SCANLAB galvo scanners? A: Yes — F-Theta lenses use standard mounts and pair directly with SCANLAB and other mainstream scanners; we can help with full system sizing.
4. Q: What is the mounting standard? A: Standard thread/flange mounting; most equivalent lenses are directly interchangeable. Send your current barrel spec and we will confirm.
5. Q: Warranty and after-sales? A: Genuine import with warranty per contract; technical support and lens inspection services are available.
6. Q: Lead time? A: German import; typical lead time 2–4 weeks (depends on stock and logistics); bulk orders can be pre-stocked.
