About WELDDING LENS D20*3.5 F800

A D20 3.5 F800 welding lens is a laser focusing lens used in fiber laser welding or cleaning machines. It focuses the laser beam to a precise spot for efficient processing.

Technical Specifications

Diameter (D20): 20 mm
Thickness (T3.5): 3.5 mm
Focal Length (F800): 800 mm (long focus distance)
Material: Usually high-purity quartz / optical glass
Wavelength compatibility: Commonly 10641090 nm (fiber laser range)
Transmittance: 99% (high efficiency)

Function

Focuses the laser beam into a controlled spot
Improves energy density and precision
Ensures better welding quality and penetration

Applications

Laser welding machines
Laser cleaning machines (F800 is commonly used for cleaning)
Sheet metal fabrication
Automotive & industrial parts

Important Notes

F800 = long focal length, so:
- Larger working distance
- Wider beam spot
- Often used for cleaning rather than welding precision jobs
Must be installed in correct direction (convex/flat side orientation matters)
Needs regular cleaning/replacement to maintain performance
