Reflective lenses in fiber laser welding/cleaning torches (typically 1080nm-1064nm wavelength) are critical components that focus or direct the beam while withstanding high power. These, along with protective windows, require regular, delicate cleaning with absolute ethanol or acetone to prevent damage from metallic spatter and dust.
Key Aspects of Reflective Lens & Torch Maintenance
Purpose: Reflective mirrors/lenses are used in handheld laser welding and cleaning heads (such as Qilin or WSX models) to manage the high-power beam.
Cleaning Process:
Pre-cleaning: Use a blower to remove loose contaminants from the surface.
Solvent Cleaning: Apply high-purity ethanol or acetone to a cotton swab and gently wipe, moving in one direction to avoid streaks.
Maintenance: Regular cleaning (ideally weekly) is required to maintain, or restore if possible, the lens, although metal spatter often requires replacement.

Fiber Laser Welding Applications
Precision Welding: Used for thin, delicate metals using pulsed lasers, or medium-to-thick sections using Continuous Wave (CW) lasers.
Automotive/Aerospace: Welding body panels, gears, and structural components due to low heat distortion.
Medical/Electronics: Creating clean, precise, and sterile joints.
Fiber Laser Cleaning Applications
Weld Prep: Removes contaminants like oil, paint, and oxides from surfaces to ensure weld integrity.
Post-Weld Cleaning: Removes heat tint, oxides, and slag from stainless steel welds.
Surface Preparation: Removes coatings, paint, and rust, or creates surface textures to improve adhesion for coating or adhesive bonding.
Mold Maintenance: Cleans contaminants and residue from industrial molds without removing base material.
Fiber Laser Repair/Refurbishment
Mold Repair: Laser cladding (using filler material) repairs worn-out or damaged molds in the plastic injection, automotive, and aerospace industries.
Surface Renovation: Removes rust, paint, or anodized finishes from metallic parts to restore them to a usable state.
Weld Rework: Cleans existing welded surfaces in hard-to-reach areas, allowing for re-welding without manual grinding.

Q1: Are these compatible with my handheld torch brand?
Yes. Our mirrors are standard sizes designed for all major Fiber brands, including Raytools, SUP, Qilin, Hanwei, and WSX.
Q5: How can I extend the life of my reflective mirror?
The most important step is to check your Protective Window daily. If the protective window is burnt, dust will enter the upper chamber and damage the reflective mirror.
Question :When can I get the price?
Answer :We usually quote within 24 hours after we get your inquiry. If you are very urgent to get the price, please tell us in your email so that we will regard you inquiry priority.
Question:Which port is the nearest from your company ?
Answer :The Qingdao port is the nearest.
Question:why should you buy from us not from other suppliers?
Answer :We have the same quality as others, but offer preferential factory prices.
Question:Can I get a lower price if I order large quantities?
Answer :Yes, cheaper prices with more bigger quantity orders.
