Precitec Original Collimating & Focusing Lenses (D30/D37)
Original Precitec optical lenses for fiber-laser cutting heads. Select your Diameter (D30 or D37), Focal Length (F100–F300) and Spec (Collimating / Focusing / Aspheric + power rating). Built for 1 µm Yb-fiber lasers and high-power industrial cutting.
- Compatibility: Precitec laser heads (verify D30/D37 and focal length before ordering).
- Types: Collimating (beam collimation) & Focusing (spot formation); aspheric options for high-power heads.
- Power ratings: 4–30 kW (see variant list).
- Optics: Laser-grade fused-silica substrates with high-damage-threshold AR coating for 1030–1090 nm.
- Weight: 0.2 kg per item. Tax-exempt on this store.
- Packing: Each lens is individually protected and sealed for safe transport.
How to choose the right lens
- Confirm diameter on your head label or existing lens: D30 or D37 (must match mechanically).
-
Identify function:
- Collimating lens (near the fiber input) converts the diverging beam to a parallel beam.
- Focusing lens (above the nozzle) concentrates the parallel beam into the cutting spot.
- Pick focal length by process needs (shorter F → smaller spot & shallower depth; longer F → larger process window & more standoff).
- Match power level: for ≥15 kW, choose aspheric options where noted to reduce aberrations and thermal load.

| Recommendation | Use aspheric versions on high-power heads to reduce aberration and maintain spot quality |
Installation & maintenance
- Environment: Work in a clean, enclosed, dust-free area. Wear powder-free nitrile gloves and a mask.
- Check parts: Verify diameter and F value; inspect O-rings, spacers, and seats for residues.
- Orientation: Keep coated surfaces clean; follow manufacturer orientation marks if present.
- Mounting: Place gently into the holder; tighten the retaining ring to the manufacturer’s torque (do not overtighten).
- Alignment: After collimator replacement, check beam collimation and nozzle centering.
Cleaning guideline
- Blow off loose particles with filtered, oil-free air from center to edge.
- Single drag-wipe with lint-free lens tissue lightly wetted with 99.9% IPA; avoid circular scrubbing.
- Do not touch the surface; never reuse tissues; air-dry in a clean environment.
FAQ
Q1. Do I need an aspheric lens?
For heads ≥15 kW, an aspheric collimating lens (and for 30 kW also the F300 focusing lens) helps maintain beam quality and stability.
Q2. Can I switch between D30 and D37?
No. The diameter must match the head design. Always follow the label or the size of your existing optics.
Q3. Can I combine F100 collimation with F150 focusing?
Yes—collimating and focusing focal lengths are chosen together to achieve the target spot size and standoff; use the same combination as your OEM setup unless process changes are intended.
Q4. What else should be checked or replaced?
Protective window, nozzle, and ceramic ring. A contaminated window can quickly damage a new focusing lens.
Recommended accessories
- Protective windows (QBH sizes matching your head)
- Nozzles (single/double layer, conical/straight)
- Ceramic rings & sensor cables
