Designed for biological, geological, forensic, and environmental applications, the Olympus stereo MVX10 is a research grade fluorescence microscope with a viewfield up to 55mm and zoom ratio of 31:1. When the 0.63X and 2X objectives are employed the zoom capability gives magnifications from 4X to 125X.
As mentionned, at research grade this scope can be used for brightfield, darkfield, polarization, and fluorescence imaging.
Significantly, this scope has the typical
long working distance and widefield of a stereo microscope combined with
the high numerical apertures of a compound microscope that allows it to
be an effective fluorescence platform.
This version of an Olympus stereo microscope has a high degree of fluorescence detection even at low magnification.
The widefield eyepieces are adjustable to 23 degrees of inclination for user comfort and are able to be independently focused.
The observation tube allows the user to choose between having the stereo effect on or off. Mated with a two position revolving nosepiece the planapochromatic objectives, 0.63X, 1X, and 2X are specifically designed for the MVX10 and have numerical apertures of .15 to .50.
The 2X objective has a correction collar for manual aberration correction and has a resolution of 1500 lines /mm.
Additional features include:
Transmitted light illumination – The MVX10 can use either a 30W halogen bulbs or a 150W fiber optic illuminator.
Fluorescence Illumination -- Dichromatic mirrors,
a four position turret for the filter blocks designed to absorb stray
light, and an objective that act as both the imaging and illuminating
lens support fluorescence microscopy. Also, a 100W mercury or 75W xenon lamp in a lamphouse that has an aspherical and apochromatic corrected collector lens completes the package.
Focusing – These Olympus microscopes have a motorized focusing at a rate of 0.3 to 1.5mm/second and a resolution of one micrometer.
Stage – The mechanical stage has coaxial X and Y controls and can support an object weighing up to 1000 grams. A circular rotary stage and a heated stage are also available for these Olympus microscopes.
These Olympus stereo microscopes are
a compromise of features in that either 100% of the light may be sent
to the binocular tubes or to the camera. Many microscopes in this class
have the ability to fractionally split the light to allow simultaneous photomicrography in combination with visual observation through the binocular head.
double-edged sword aspect of this microscope is in the area of the
stereo microscope/fluorescence imaging compromise. In other
stereo microscopes fluorescence use
is impaired because each optical path gets only half of the transmitted
light and this reduced illumination degrades the fluorescence signal
detection and imaging.
This microscope overcomes that problem by having a
single optical path with a different method for dividing the light
however, this reduces the three dimensional effect for which
stereo microscopes are famous.
Olympus Stereo SZX16
SZX16 is also a research grade Olympus stereo microscope that shares many of the
While it is an advanced research microscope it does
not have the same performance as the other scope. It has a maximum
numerical aperture number of .30 and a resolution of 900 line pairs/mm.
It also may be used for brightfield, darkfield, fluorescence, and
polarized light imaging and has six available objectives with the four standard parfocal lenses having
magnifications of 0.5X, 1X, 1.6X, and 2X.
Combined with a zoom ratio of
16.4:1 this yields a zoom range of 7.0X to 115X for easily shifting
from a specimen overview to detailed examination. Using the SDFPLAPO2XPFC objective with the WHN 10X ocular can increase the zoom to a maximum of 230X.
As with the MVX10, this version of an Olympus stereo microscope has
a long working distance facilitating manipulating the specimen or
otherwise having room for the user’s hands under the objectives.
unit also has a revolving turret holding two objectives at a time.
For fluorescence imaging, the reflected light illuminator provides homogenously bright light and these
Olympus microscopes have a five position filter turret with nine available filters capable of detecting even weak fluorescence at low magnification.
This model is ergonomically engineered to allow for comfortable extended use and has easily accessible controls. Additionally, other features of the SZX16 include:
Motorized features – The unit has an optional motorized focus and zoom with an available foot switch as well.
Digital imaging – The SZX16 has a tilting trinocular head that allows the user to switch between viewing and documentation. This unit is also able to use the Olympus cellSens digital imaging software.
Stage – The mechanical stage is wide to accommodate large objects such as petri dishes.
Illumination -- Different lamp bases are available to meet different lighting needs. The SZX2-ILLB and the SZX2-ILLK lamp bases, with built-in cooling fans, are best suited for oblique illumination. The SZX2-ILLD, also with a cooling fan, provides for bright darkfield illumination. For LED illumination, the SZX2-ILLT provides consistent illumination with no heat to damage delicate or living specimens.
The LED system has a bulb life of 10,000 hours and uses a fraction of the energy of a standard 30W halogen bulb.
While these Olympus stereo microscopes
don’t quite possess the performance level of the MVX10 it is a very
sophisticated and versatile scope and is designed to meet the normal
needs of the various forms of imaging used in microscopic research.
Olympus Stereo SZX10
This Olympus stereo microscopealthough with a lessening of the advanced capabilities of the SZX16, is engineered for routine research use. With a zoom ratio of 10:1, the SZX10 has a numerical aperture of 0.2 and a
resolution of 600 line pairs/mm.
This scope is well suited to
measurement and verification tasks because the optical system is
designed to eliminate any distortion. With a maximum magnification of 126X, this scope also has the typically long working distance of a stereomicroscope of 171mm.
offering a widefield view of 69.8mm, this scope can be used for
brightfield, darkfield, polarization, and fluorescence imaging and has
eight available objectives.
For illumination this scope also uses the SZX2-ILLB, SZX2-ILLK, SZX2-ILLD, and SZX2-ILLT lamp bases.
observation tube can be inclined up to 45 degrees and the eyepieces are
individually adjustable. With a trinocular head, this scope is a good
imaging platform and can accept the Olympus cellSens digital imaging software.
Observation accessories for the SZX10 include
an optional side-by-side discussion tube for instruction or
consultation with another researcher as well as a face-to-face tube
enabling the secondary observer to assist the user in tasks under the
A drawing attachment is also available to aid in sketching
These Olympus Stereo microscopes - MVX10; SZX16 and the SZX10, may be used for brightfield, darkfield, polarization, and fluorescence
They excel as stereo microscopes in the field of fluorescence
use because they are able to detect low excitation in low magnification
levels and still retain some degree of the trademark three dimensional effect of a stereo microscope.
