Laser Focusing Lenses
A focusing lens concentrates the collimated beam inside a fiber-laser cutting or welding head down to a small spot at the workpiece.
Share requirements, quantities and a drawing if available. Specifications and supply terms require confirmation.
Overview
A focusing lens concentrates the collimated beam inside a fiber-laser cutting or welding head down to a small spot at the workpiece. It is commonly sourced together with a matching collimating lens as a set for a given head model — a real, documented market pattern, not an assumption about Dongqiao's own product bundling. Procurement review should center on forming a laser waist at a defined working distance without assuming a catalog focal solution.
Key Selection Points
- Commonly sourced as a matched set with a collimating lens for a given head model

Lens Geometry & Selection Guide
This module explains how lens geometry changes the selection path and the information required from the optical design. For Laser Focusing Lenses, the module focuses on forming a laser waist at a defined working distance without assuming a catalog focal solution.
- Show surface orientation, optical axis and conjugate or beam condition in the drawing.
- Include focal length, prescription and aberration targets with the enquiry for feasibility review.
- State tolerance and manufacturable-range requirements on the drawing for review.
- Product-specific review: connect laser wavelength with target spot or working distance and document the trade-off against a laser collimating lens.

Frequently Asked Questions
Do I need this together with a collimating lens?
Focusing and collimating lenses are commonly sourced together as a matched set for a given cutting-head model in this market — see Laser Collimating Lenses.
Which specification should be fixed first for Laser Focusing Lenses?
Begin with laser wavelength. It determines how input beam diameter and divergence and target spot or working distance should be evaluated before the mechanical details are finalized.
When is Laser Focusing Lenses a better fit than a laser collimating lens?
Choose between them by testing the requirement for forming a laser waist at a defined working distance without assuming a catalog focal solution. If that requirement is absent, the comparison product may provide a simpler procurement path.
What should an RFQ for Laser Focusing Lenses include?
Provide wavelength, beam profile, input diameter, desired focus location and power regime. Also include quantity, drawing revision and the required acceptance evidence. Final availability is confirmed during quotation.
Which details for Laser Focusing Lenses still require supplier verification?
Actual material and coating availability, dimensional limits, tolerances, inspection reports, MOQ and lead time cannot be inferred from this page and must be confirmed against the RFQ.
