Newport's high power meniscus lenses are designed to meet the demanding requirements of ND:YAG laser applications. These lenses are manufactured to tight tolerances using master test plates to ensure minimum wavefront distortion. Tight surface quality tolerances minimize scatter and do not allow laser power to localize on the optical element, insuring that no damage takes place on the bare or coated lens.

The UV grade fused silica material provides maximum transmission from 195–2100 nm. It will not fluoresce under UV light and is resistant to radiation. And for high-energy applications, the extreme purity of fused silica eliminates microscopic defect sites that could lead to laser damage.

These singlet lenses are available either uncoated or coated with a choice of laser line V-coating for all of the ND:YAG fundamental and harmonics: 1064, 532, 355, and 266 nm. A standard diameter of 50.8 mm allows for quick, easy mounting in many Newport holders when building experiments or prototypes.
