YAG Laser Focusing Lens 30mm Diameter 79.9mm Focal Length
NYDL-30-80PY1
YAG laser focusing lenses are air spaced triplets or doublets for YAG wavelengths. The elements are made of crown glass of lower dispersion and flint glass of higher dispersion. These lenses are optimized for spherical aberration and coma. With its spot size designed to be smaller than or equal to the diffraction limited spot size for beams at 1064nm.
◦These lenses are chromatically corrected so that any He-Ne guided beam or visible video monitor beam will remain focused in the same position as the YAG beam. All elements are coated with a laser-resistant narrowband multi-layer anti-reflection for YAG: 1064nm and He-Ne: 633nm.
◦We offer optical protective windows to prevent damage to the lens by absorbing high levels of energy from inadvertent back reflection of the incident beam. These protective windows can be easily installed to the focusing side of the lens.
