Technical Note On Ultra Low Absorption
Coating: LOM's new Ultra Low Absorption anti-reflective coatings are ideally
suited for high power CO2 laser cutting up to 6kW. With absorption <0.15% and
transmission >99.4% this next generation lens technology offers better power
handling capability and a stable focus for high power cutting where other lenses
fail to perform. Call LOM for a datasheet on our new ULTRA Lens Technology.
