Products description

XDS-3FL is an advanced inverted epifluorescence microscope. Thanks to its special FLUO objectives, designed with quartz and special glasses (low in auto-fluorescence),
XDS-3FL is upgradable with every kind of fluorescence filterset.
The instrument offers, in the same unit, brightfield and phase contrast capabilities, thus extending its potentials to most multi-contrast applications The epifluorescence optical system is implemented via the standard excitation filter-dichroic mirror-barrier filter combination, applied to a 100W Hg lamp. It is supplied with EWF10x/22mm extra-widefield eyepieces, long working distance IOS FLUO objectives, and a double filterblock set (blue and green excitation as standard configuration).
The extensive range of optional accessories allows a quick interchange of contrast mechanisms, and it is optimized for multi-contrast observation without removal of the specimen
from the stage Every control is easy to reach, every component has been designed with ease of use in mind. The focussing and specimen
translation controls are designed to allow to rest the wrists on the table.
The brightfield light intensity regulation is placed very close to the focussing knobs.
The specimen stage is fitted with a special glass insert, that allows to see the objectives, for immediate identification of the magnification setup. XDS-3FL is comfortable for the operator.
The 22 mm extra-wide field is pleasant to use, and minimizes operator stress.
The special eyepieces are designed for eyeglass wearers
