CFI Super Fluor Series

Objective lenses with superior UV transmission and unsurpassed chromatic correction.

CFI Super Fluor Series objective lenses provide the highest level of ultra-violet transmission, exceptionally high N.A.s, and terrific chromatic correction. Thanks to outstanding transmission below 340nm, Super Fluor objectives are the ideal choice for fluorochromes like indo-1, fura-2, and fluo-3. These objectives also have improved signal-to-noise (S/N) for short wavelengths, (due to low auto-fluorescence materials,) and have high N.A.s, making the fluorescence images they produce significantly sharper and brighter. They are also a great choice for photo-activation of caged compounds.
