Dual Focus
Dual Focus, a unique Olympus optical innovation, allows the
user to select between two focus settings. With the simple push
of a scope button, the desired depth of eld for observation can
be optimized to either the near eld or normal eld.
NBI (Narrow Band Imaging)
NBI in EVIS EXERA III 190
Series scopes provides twice
the viewable distance of EVIS
EXERA II 180 Series scopes.
RIT (Responsive
Insertion Technology)
RIT combines three proprietary
insertion tube technologies: HFT (High Force Transmission),
PB (Passive Bending), and variable stiffness. These technologies are
designed to facilitate complete colonoscopies by improving scope
handling, insertability, and ergonomics. PB helps EVIS EXERA III 190
Series scopes move through acute bends in the colon. HFT provides
improved operator control for both pushing and twisting maneuvers.
Variable stiffness allows the physician to adjust the rigidity of Olympus
scopes as needed by simply turning an adjustment ring on the
scope’s control section.
Enhanced Image Quality
An enhanced level of resolving power is achieved owing to a
new optical system. Signicantly less halation and noise is
visible on screen. Improved optics, a brighter image, increased
contrast, reduced noise, and reduced halation are the result of
a new CCD available in the EVIS EXERA III, providing superior
image quality even during electronic zoom.
ScopeGuide
ScopeGuide is an integrated
technology in EVIS EXERA III 190
Series HQ colonoscopes.
ScopeGuide provides real-time 3D
visualization of scope position and
conguration. This new level of
visualization provides physicians with the ability to recognize loops
as they form, potentially leading to shorter insertion time and less
patient discomfort.
Waterproof One-touch Connector
A new connector design
minimizes the effort required for
setup prior to and in between
cases. In addition, it is fully
submersible and eliminates the
need for a water-resistant cap
and the associated risk of an
expensive repair due to
accidental immersion.
