LINOS F-Theta-Ronar Field Lens F=254mm 157x157mm 1064nm Fiber Laser Marking
LINOS F-Theta-Ronar Field Lens F=254mm 157x157mm 1064nm Fiber Laser Marking
This F-Theta-Ronar series field lens from LINOS, Germany features a 254 mm focal length and 157 * 157 mm scanning field. Designed for fiber laser and Nd:YAG laser marking and engraving systems, this large-format all-round model delivers wide-field, low-distortion, high-uniformity scanning focus. The F=254 mm configuration is ideal for large-area marking applications including nameplates, full-sheet marking, and large workpieces. 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 scanning field does F=254 mm cover?
A: Typical 157 * 157 mm — ideal for large-format marking; confirm with the official datasheet.
Q: Which lasers and scanners does it pair with?
A: Suits 1064 nm fiber lasers and Nd:YAG lasers, and mainstream scanners such as SCANLAB basiCube / intelliSCAN.
Q: Standard F=254 vs Fused Silica F=255 (170 *170)?
A: Field sizes are close; fused silica optics handle higher power and thermal stability better, at a higher price. Choose the standard version for routine marking.
Q: Which models are available in this series?
A: 15 models from F=100 to F=420, including standard, telecentric, 532 nm and fused silica versions — see the model table above.
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 lead time?
A: Genuine import with warranty per contract; technical support and lens inspection services available. Typical lead time 1-2 weeks; bulk orders can be pre-stocked.
