 | The Carl Zeiss Axioskop 2 FS and Axioskop 2 FS mot Research Microscopes are ideal platforms for successful experiments in electrophysiology.
An innovative feature of special advantage for the user is a quick-switch linear objective changer providing fast and absolutely precise change between two different objective powers with a single flick of the hand, without conversion or interference with the experimental setup. Once adapted to the specimen, the stage position remains unchanged during the experiment - focusing acts exclusively on the objective, and the operator cannot make any mistake in handling the controls.
The Achroplan water immersion objectives (all of the ICS infinity type) have been specially designed for use in electrophysiology. The series provides magnifications between 10x and 100x. The 40x with its numerical aperture of 0.8, a working distance of 3.6 mm and excellent transmittances for the near UV and near IR deserves special mentioning. The other objectives can also be used with these spectral ranges.
For the first time, an electrophysiology microscope is available in two versions: the manual Axioskop 2 FS and the motorized Axioskop 2 FS mot. Whereas focusing in the former is manual, the latter has a motor-driven Z motion for focusing at selectable speeds, by selectable increments, with position memory, homing function and more.
All microscopical contrasting techniques - from brightfield to fluorescence - can be employed without restrictions. Everything needed for these techniques is already incorporated in the Axioskop 2 FS stand, so that no conversion is required. The operation of DIC, to be set by the Senarmont principle, is particularly simple.
The various condensers available for the Axioskop 2 FS microscopes includes one of NA 0.8, which is equipped for brightfield, phase contrast and DIC and provides a working distance of 7 mm. |
