CMark laser lens
The CMark COâ‚‚ laser focusing lens concentrates and directs the beam onto a precise point on the material being processed.
By reducing beam diameter, it increases energy density — essential for high-precision applications such as fine engraving, clean cutting, and micro-machining.
Focal length directly affects marking sharpness and working area size: a short focal length delivers higher resolution and finer detail, while a longer focal length provides a larger marking surface, better suited to bigger parts.
Precise focus adjustment ensures consistent marking quality, with a sharp, uniform finish and no power loss, even at high operating speeds — critical for maintaining performance throughout the production cycle.
The lens can also be adjusted to suit the material being processed, whether wood, plastic, cardboard, glass, or other substrates. This adaptability helps prevent overheating, carbonization, or surface damage, ensuring quality marking across a wide range of materials.
Technical data sheet
The focusing lens ensures consistent performance and marking quality, with the following advantages:
– High precision: sharper marking and finer engraving detail.
– Optimized for COâ‚‚: operates at a 10.6 µm wavelength, ideal for organic materials and certain plastics.
– Multiple focal lengths: adapt spot size and working area to suit the application.
– High energy efficiency: excellent beam transmission with minimal loss.
– Thermal resistance: built for durability, even under intensive, high-temperature use.
– Full compatibility with the CMark range of galvanometer heads.
– Material versatility: suitable for plastics, glass, wood, leather, fabric, and more.
