CFI60 OBJECTIVES<br />
CFI Achromat Series for Brightfield/Ph<strong>as</strong>e Contr<strong>as</strong>t (DL)<br />
Correction for chromatic aberration in these objectives have been dramatically improved and are at the same level<br />
<strong>as</strong> the CFI Plan Achromat Series. These objectives were also corrected for spherical aberration and coma and<br />
image flatness across the 22mm field of view h<strong>as</strong> been dr<strong>as</strong>tically improved.<br />
The result: truly exceptional quality for this cl<strong>as</strong>s of objectives.<br />
The DL ph<strong>as</strong>e contr<strong>as</strong>t objectives in this series have more contr<strong>as</strong>t than the DLL objectives for enhanced contr<strong>as</strong>t<br />
with unstained specimens.<br />
