• 175x175mm Field Lens: OMTech’s F-Theta lens is ideal for laser marking, engraving, image transfer, material processing, and cutting systems. It creates vivid markings and flawlessly completes even your most intricate designs through its 6.9x6.9 inch scanning area.
• Ultra-High Transmittance: This field lens for 1064 nm lasers above 80W provides up to 99% throughput with negligible distortion thanks to its crystal clear and precision engineered fused silica construction.
• Consistent Performance: Our F-theta scanning lens provides fast positioning and precision focusing so you can mark steel, aluminum, gold, silver, and more with a consistently exact 45 micron spot size anywhere in the lens's 17.5x17.5 cm field.
• Lasting Service Life: The fiber laser lens's double-sided multilayered coatings improve natural optical properties and ensure outstanding scratch and damage resistance during daily use, for a long service life and reliable performance.
• Install in a Flash: The standard M85x1 threading offers easy installation, quickly replacing or upgrading the old lens in OMTech or most other laser marking machines on the market.

Description:

Engrave better and faster with OMTech’s ultra-high transmittance field lens!

Whether you're replacing an old scan lens or upgrading, this fiber laser optic offers extreme precision and peak performance across its entire 175x175mm scanning area to get all your stone, glass, and metal marking done right. Manufactured from premium fused silica, our galvo scanner lens boasts strongly antireflective coatings on both sides to give our industry-leading lenses a light transmittance rate better than 99% at the 1064nm wavelength critical for CW, QCW, and Nd:YAG lasers. To ensure the longest service life, the coating on both sides of the lens also helps it resist scratches and other damage. The standard M85x1 threading lets you easily install this optical lens onto the galvanometer of OMTech's fiber laser marking machines with 80W or higher power.

With OMT's brand-new F theta lens, your laser engraving, cutting, etching, and marking work has never been easier!
