Optical Achromatic Lens - Chinaprice: contact company for price
Glass lens element cemented to a negative high- index Flint Glass lens
element. The elements are chosen so as to cancel chromatic aberration at
two well- separated wavelengths, usually in the blue and red region of
the spectrum. Focal length is constant at those two wavelengths and
focal length shifts are virtually eliminated across the visible
wavelengths. One frequent use is to achieve diffraction limited focusing
of a laser beam. Negative Achromats are typically used when there is a
need to eliminate chromatic aberration. In addition to reducing
chromatic aberration at the design wavelengths, spherical aberration and
coma are greatly reduced.
