Positive Achromatic Lenses, AR400-700/650-1050/1050-1700nm
Achromatic lenses are professionally optimized to effectively reduce and eliminate chromatic aberration, while their advanced achromatic design also suppresses spherical aberration for superior optical performance. Delivering a finer focusing spot than conventional singlet lenses, these lenses are well suited for detection, spectroscopy and other high-precision optical applications. Tuniu Optics provides achromatic lenses with a range of anti-reflection (AR) coatings to meet diverse application needs.
