Microscope Objective HC PL FLUOTAR 20x/0,55
$undefined
PL Fluotars are powerful universal objectives with outstanding chromatic correction for at least three wavelengths which makes them suitable for fluorescence imaging.
Field planarity (PL) is computed for a 25 mm field of view. They are made of special glass to enable maximum transmission. This makes them powerful photon collectors in fluorescence microscopy.
Leica’s Fluotar portfolio features various application-optimized correction collars (CORR) to compensate for external influences such as temperature, coverslip thickness and immersion media.
