Cutting, marking, and cleaning — all three tasks can be done with the same laser marker. The secret? Changing the lens. In this video, we compare different lens sizes to show you exactly how lens choice affects dot size, working area, power density, and the applications you can run.

🔬 WHAT THE LENS DOES:
– Focuses the laser beam into a single point — determines dot size and working field
– Small lens = smaller spot, higher power density, narrow depth of field
– Large lens = larger spot, wider working area, forgiving on uneven surfaces
– Medium lens = the universal sweet spot
📏 LENS SIZES COMPARED:
– Small lenses (50×50, 75×75 mm): deep engraving, fine detail, miniature work, reflective metals (silver, gold), and even cleaning tasks
– Large lenses (300×300, 400×400 mm): large workpieces, uneven surfaces, deeper cutting
– Medium lenses (200×200 mm): all-rounder for mixed jobs — solid detail and work area
🛠️ NEED A BIG WORKING FIELD WITH A SMALL LENS?
– The Wattsan FL GT gantry marker scans while moving — working tables from 600×600 mm up to 1,000×1,000 mm with compact lens performance.
