Interchanging low and high magnifications without changing objectives.

A new concept in vibration-free design.
A major concern for researchers conducting electro-physiology experiments is the vibration which occurs when switching objectives and the resulting interference this can cause to the specimens and adjacent equipment. To solve this problem, Olympus introduces a new concept — the provision of an intermediate magnification changer in combination with the new High N.A. long working distance 20x objective that allows the user to switch between low and high magnifications without the need to switch objectives.

New 20x objective (XLUMPLFL20XW) N.A. 0.95; W.D.: 2.0mm
The new 20x water immersion objective makes high-resolution observation possible with a wide range of intermediate magnification lenses. Since exchanges between low and high magnification are performed through the intermediate magnification changer, vibration is reduced to a minimum and the usual concern about collisions between objectives and patch clamp electrodes is eliminated.
Simultaneous fluorescence and IR-DIC observations
With the included 690nm dichroic mirror in the WI-DPMC, fluorescence light is sent to the front port, and IR-DIC light is sent to the back port allowing two cameras to image simultaneously with no vibration introduced by light path selection.
Variable magnification dual port (WI-DPMC)
The WI-DPMC rear camera port includes a 2 position intermediate magnification selector. A high magnification 4x intermediate lens is included and a (0.25x, or 0.35x) low magnification lens is optional. High or low magnification selection is via a single lever with no click-stops or detents allowing a specimen to be scanned and measured with minimal disturbance from vibration. 775nm and 900nm IR-DIC compatible.
*Available for 0.5x, 1x and 2x intermediate magnification lenses by special order.
Variable Click-stops
All click-stops, as when selecting between camera and observation modes, can be adjusted to the point of no click and thus no vibration.
