Near Infrared Achromatic Lens / DL-PNIR
By bonding two lenses with wavelength dispersion of different refractive index the resulting component will provide reduced spherical aberration and chromatic aberration than that of a single spherical lens.
These achromatic lenses can be used as a focusing lens for YAG laser (1064nm) or LD of the nearinfrared.
