Product Description

Relfar lenses are typically made of fused silica and optimized for performance at a wavelength of 1064nm.

Protective Lenses
Purpose: To protect internal optical components from dust, splashes, and contaminants.
Common Sizes: 20x2mm, 25x2mm, 30x2mm, 43x2mm, and 48x3mm.

Collimating & Focusing Lenses
Purpose: To precisely align and focus the laser beam to ensure the quality of welding or cutting.
Common Specifications:
D16: e.g., D16F50T5.
D20: e.g., D20F50T5, D20F150T4.75, D20F200T3.8, and D20F600T5.5.
D30: e.g., D30F600T4.

Reflective Lenses

Applications: Used for optical path reflection in cleaning/welding gun heads such as FWH20.
Typical Specifications: 27 x 142 mm (27 x 14 T2), usually with a base.

Maintenance and Care
Regular maintenance is required to maintain optimal performance and extend lens life.
Cleaning Method: Apply isopropyl alcohol or acetone to lens cleaning paper and wipe horizontally in one direction. Do not apply excessive force to avoid scratching the surface.
Replacement Frequency: As a consumable item, protective lenses should be replaced promptly if severe burning or contamination occurs after prolonged high-intensity use to prevent damage to the internal lens.

NOZZLE
The nozzle focuses the plasma arc and the gas that surrounds it to make a clean and precise cut. A nozzle with a larger opening is used for gouging, while a nozzle with a smaller opening is better able to direct the gas and so is used for fine, detailed work.
 

Laser Protective Mirror
Thoroughly clean both the laser focus lens and the lens mounting area on the laser machine before installation.

Laser welding graduated tubes (or scale tubes) are stainless steel nozzle connectors for handheld fiber laser welders (e.g., IPG LightWELD, Qilin, SUP, Raytools) that allow for precise, adjustable focal length positioning and improved, stable gas flow. They enable accurate, consistent welds by facilitating easy, hand-held, operation

Why Choose Our Scanning Mirrors?

Lightweight Silicon (Si): Specifically designed for "Wobble" welding heads (SUP/Qilin/Raytools). The low mass allows the motor to oscillate up to 300Hz without overheating the driver.

High-Conductivity Copper (Cu): Best for 3000W+ Cleaning. Copper dissipates heat 2.5x faster than Silicon, preventing "Focus Drift" during long-duration rust removal.

Imported AR Coating: Our mirrors use high-durability coatings that resist "pitting" and environmental humidity, extending service life by 30%.

Compatibility Guide

Our mirrors are 100% compatible with the following handheld laser systems:

Welding Brands: SUP20S/21S/23S, Qilin, Hanwei, Raytools BW101/BW102, WSX.

Cleaning Brands: Max/Raycus based cleaning torches, standard Gantry cleaning heads.

Maintenance & Safety Tips

Daily Check: Always inspect the Protective Window first. A burnt protective window is the #1 cause of damage to the reflective mirror.

Cleaning: Use only 99% anhydrous alcohol and specialized lens paper. Do not use industrial cleaners or rough cloths.

Storage: Keep spares in a dry, vacuum-sealed environment to prevent oxidation of the reflective coating.

Application

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. 

Company Profile

FAQ

 

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.
