Achromatic Cemented Lens is used to minimize or eliminate chromatic aberration. The achromatic design also helps minimize spherical aberrations. Achromatic Cemented Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Cemented 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.
The achromatic cemented lens can also be called an achromatic doublet lens or achromatic cemented lens. If you want to know more information, please contact us.
