YAG Laser Focusing Lens / NYTL_NYDL

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.
