Near Infrared Achromatic Lens
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 near-infrared.
The lens design is optimized so that the focal length change is minimized in the near infrared region. The focal length matches at 700nm, 880nm, 1100nm wavelengths and is optimized to minimize aberrations.
It is suitable as a collimating lens not only because chromatic aberration but also spherical aberration is collected.
