Achromatic Lenses
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. Achromatic Lenses, which are often designed by either cementing two
elements together or mounting the two elements in a housing, create smaller spot sizes than comparable singlet
lenses.
