Achromatic Lenses

Most achromatic lenses, are doublet lenses typically corrected for spherical and chromatic aberration at only two wavelengths (e.g. red and blue for visible).  However, our catalog achromatic lenses are corrected at three wavelengths (e.g. blue, green, and red for visible).  OptoSigma offers achromatic spherical lenses for use in the  Visible, and NIR wavelength ranges. We also manufacture custom solutions in case our many standard lenses do not meet your requirements.
