Applications:
Projection Systems, Imaging Systems, Laser Measurement Systems, collimators, focusing lenses, light collectors, achromatic telescopes, microscopes, and photographic lenses. etc.

Description:
Achromatic Lenses are used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses.
 
Compound lens system that forms an image free from chromatic aberration. Cemented achromatic lenses significantly reduce coma and chromatic aberration. Best used to replace single components where performance must be improved.
 
Achromatic lenses can be used as collimators, focusing lenses or light collectors. They are designed to eliminate chromatic and spherical aberrations and perform well for all paraxial imaging tasks. These lenses are coated with single layer antireflection coating to reduce surface losses in the visible regions.
