Laser processing and marking

What do components in this industry have to carry

The optical path of laser equipment has two hard requirements: first, the components must withstand power density, and second, the energy distribution at the focal point must be stable. The protective lens of cutting and welding equipment is directly blocked on the splash path and belongs to consumables, which are sensitive to the hardness and wiping resistance of the film layer; Marking and engraving equipment place greater emphasis on the consistency of focal length and wavefront quality of field lenses and focusing lenses.

Common components

• Laser protective lenses: commonly used 1064nm and 532nm, with the lens holder selected according to the equipment model
• Focusing lens: single lens, compound lens, collimating lens, matched according to focal length and aperture
• Marking airport mirror: Match according to the marking format, and confirm the interface with the equipment factory
• Reflection mirror and 45 degree reflection mirror: used for optical path turning

Key selection points

First, confirm the laser type and wavelength, and then confirm the power density and spot diameter - these two factors determine the film design and substrate thickness. The optical path space on the device side (mirror holder size, incident angle) needs to be provided together to avoid components not being able to fit in.
