Carbon dioxide (CO2) precision marking lenses have coatings that provide <0.2% total absorption values to remain cooler, while maintaining sharper cuts with fewer passes. Suited for most engraving and marking lasers, these OEM optics are offered in 0.5–1.5 in. sizes with focal lengths from 1 to 25 in., in 0.5 in. increments. Available off-the-shelf, they meet ISO-10110 specifications for optical elements.
