Optical Glass Achromatic doublet lenses

 

 

Achromatic doublet lenses ("achromat") are designed to eliminate chromatic and spherical aberrations inherent in singlet lenses.  When used on-axis,  an achromatic lens focuses an parallel input beam to a perfect "point", limited only by the effects of diffraction. This performance can be achieved over a broadband of wavelength.   Achromatic lenses can be used to collimate and focus laser beams.  They can also be used for high-quality imaging on-axis.  However,  the off-axis performance is significantly worse than the on-axis performance.  If your application requires good optical performance off-axis as well as on-axis,  multi-element lenses such as our digital imaging lenses are recommended.
