UV laser lens
The primary function of the UV laser focusing lens is to concentrate and direct the light beam onto a precise area of the material being processed.
By reducing the beam diameter, it increases energy density, which is essential for operations such as engraving, fine cutting, or micro-machining.
The focal length plays a key role in marking precision: a short focal length provides a high level of detail, while a longer focal length offers an extended marking area suitable for larger parts.
Optimal focus adjustment ensures a clear, uniform result with no power loss, even at high production speeds.
Finally, the lens adapts to the type of material being processed, limiting the risks of overheating, carbonization, or degradation of the part, thus ensuring consistent marking quality across a wide variety of substrates.
Technical data sheet
The focusing lens is the key component of UV lasers:
– Improves marking and engraving precision.
– Operates with a 355 nm wavelength.
– Available in different focal lengths, it determines spot size and the extent of the working area.
– Optimizes energy transmission and reduces losses.
– Ensures high durability and resists high temperatures.
– Compatible with galvanometer heads.
– Used for marking on metals, plastics, and glass.
