High-Speed Fluorescence – New External Filter Wheels for Living Cell Applications 1 | 2

Light Microscopes


Fast and Vibration-free — New External Filter Wheels from Leica Microsystems
They are fast, vibration-free due to their small size, and they offer exceptional versatility. These outstanding features are characteristic for Leica’s new fast filter wheels for excitation, attenuation and emission control. Their short switchover times render them suitable even for highly complex applications such as FRET or CA++ imaging (Fura2).
