4. Lightening
Weight has been reduced to approximately 2/3
that of conventional products by using an
aluminum objective lens barrel cover. This has
the effect of lightening the load on the devices at
objective lens up/down, suppressing vibrations
by lowering the inertial force at objective lens
switching, etc. (MPLFLN series, LMPLFLN
series)
5. Adoption of eco-lens
The glass materials of UIS2 objective lenses are
all lead- and cadmium-free eco-glass.
Features of UIS2 objective lenses
UIS2 objective lenses ensure compatibility (screw
diameter, optical performance) with the UIS optical
system and have the following features compared
to conventional objective lenses.
1. Wavefront aberration control
The Olympus UIS2 objective lenses set a new
standard, with wavefront aberration control in
addition to common performance standards of
N.A. and W.D. Olympus challenges farther
highest order optics which has not been fulfilled
by the conventional standards. We offer
excellent performance objective lenses by
minimizing the aberrations that lower resolution.
*Wave front aberration: refer to the optical terminology at the
end of this document.
2. Objective lenses with excellent image
parcentricity
High power SemiApochromatic UIS2 objective
lenses make the centration tolerance between
objective lenses on the microscope nosepiece
keep the image within the enter of the field of
view even with digital cameras. (50x or higher
power in both MPLFLN and LMPLFLN series)
3. Improvement of color reproducibility
UIS2 objective lenses realize natural color
reproduction without any chromatic shifts using
stringently selected high transmittance glass
and advanced coating technology that provides
high transmittance which is flat over an ultra-
wide band wavelength. In addition, since the
total optical system, including the tube lens is
designed to reproduce a natural color, clear
images faithful to the specimen are obtained
even with digital imaging.

Based on our conviction that the UIS2/UIS
system is the best way to maximize the
advantages of infinity-corrected optical
systems, we confidently recommend the
UIS2/UIS-featured Olympus microscope units
for all your high-precision needs in research,
inspection and production equipment.
