CFI60 OBJECTIVES
CFI Plan Fluor Series for Brightfield/Phase Contrast (DLL)
Featuring an extra-high transmission
rate, especially in the ultraviolet
wavelength, and flatness of field
comparable to the CFI Plan Achromat
series, these objectives are designed
for fluorescence observation and
photomicrography. Because of this
improvement in quality, these
objectives can function as multipurpose
objectives for brightfield,
fluorescence, polarizing, and DIC
observations.
The DLL (low contrast) phase
objectives for this series can also be
used as universal objectives for
phase contrast, fluorescence, DIC,
and brightfield techniques.

CFI Plan Fluor Series for Phase Contrast (DL)
These objectives have more contrast than the DLL objectives for enhanced contrast with tissue culture
specimens. These objectives are designed for use on inverted microscopes and therefore their markings are
upside-down for easy reading.
