Fiber laser lens
The main role of the focal lens for fiber laser is to concentrate and direct the laser’s light beam toward a precise area of the material being processed.
Beam concentration: it reduces the beam diameter to increase energy density, which is essential for cutting, welding, or engraving.
Precision and control: the focal length determines the marking sharpness and the working area. A short focal length offers more detail, while a long one covers a wider area.
Marking quality: precise focusing ensures a sharp, homogeneous result without power loss.
Material adaptation: the lens adjusts the focus according to the material, preventing overheating or degradation.
Technical data sheet
The focal lens is the key component of fiber lasers:
– Improves marking and engraving precision.
– Works with a 1064 nm wavelength.
– Available in different focal lengths, it determines the spot size and the extent of the work area.
– Optimizes energy transmission and reduces losses.
– Ensures great durability and resists high temperatures.
– Compatible with galvanometer heads.
– Used for marking on metals, plastics, and cutting thin metal sheets.
