Some of these features include an 18MP USB 3.0 digital camera, high quality infinity PLAN achromatic objectives as well as a Siedentopf trinocular head. This is in addition to a number of other important features, which increase the functionalities of the microscope, making it ideal for various uses.
OMAX 40X-2500X Phase Contrast Trinocular Siedentopf Microscope - Features and Description
Trinocular Siedentopf head - The OMAX 40X-2500X 18MP
USB3 PLAN Infinity Phase Contrast Trinocular Siedentopf compound microscope
comes with a Siedentopf trinocular head, which offers a number of
advantages. A Siedentopf microscope head allows users to change the
interpupillary distance (between 55mm-75mm) of the eyepieces without affecting
the focus. This makes it superior to the sliding binocular, where users have to
keep adjusting focus after adjusting eyepiece distance. In this case therefore,
using the Siedentopf head becomes more convenient for users given that several
users can continually adjust the eyepiece distance without affecting the focus.
This feature is also set at a 30 degree inclination and can be rotated 360
degrees, for enhanced comfort during use. In addition, the Siedentopf head
comes with a diopter on the eyepiece tube, which is an important feature that accommodates
for differences in eye sight, allowing different users to observe the specimen
Digital Image Capture
Being a trinocular head, the Siedentopf also holds a high speed 18MP USB 3.0 digital microscope camera with 0.5X reduction lens for a wider field of view. This is a high performance digital camera with the ability to capture still images and stream live videos in addition to allowing for a number of increased functionalities.
This feature also allows for the microscope to be connected to a PC using a USB cable and a software that is compatible with Windows, Mac OS X and Linux operating systems. Using this software, it becomes possible to not only capture still images and record live videos, but also measure lengths, angles, areas and edit images as desired.
PLAN infinity objectives -This being an OMAX phase
contrast microscope, it comes with four PLAN infinity phase contrast (10X, 20X,
40X(s), 100X(S, Oil)) and four high quality PLAN infinity achromatic objectives
(4X, 10X, 40X(s), 100X(S, Oil)). This therefore allows the microscope to be
used for brightfield microscopy and phase contrast microscopy. Being PLAN flat
corrected, the objectives allow for a well focused view, which also means
better viewing experience. Infinity corrected objectives are used with infinity
corrected tubes, which allows users a longer working distance as compared to
normal DIN-type objectives.
The benefit of this system is that it allows for
the sample to be placed further, therefore allowing more room for maneuverability.
A spring feature is included in the 40x and 100x objectives, which allows the
lenses to retract when they come in contact with the slide. This is an important
feature that increases protection for the lenses, and prevents them from
Together with wide field eyepieces (WF10X/18 and WF25X) users
will achieve total magnifications of 40X-100X-250X-400X-1000X-2500X for
brightfield microscopy and 100X-200X-250X-400X-500X-1000X-2500X for phase
contrast microscopy. These are indeed high magnification ranges that will allow
for a wide range of specimens to be observed.
Mechanical stage - This microscope uses a
double layer X-Y mechanical stage, which is 140mm x 110mm in size and allows for
a transition range of 78mm x 46mm. This stage having scales makes it easier for users to place the slide (with specimen) at desired areas on the stage,
which can be repeated over time with ease when focusing.
This type of stage
also makes it easier to move the slide when viewing without necessarily
touching the slide. Here, the slide, which is held in place by a pair of clips
is smoothly moved around using the appropriate knobs when trying to locate the
point of interest on the stage.
More Important Features
- 3W LED lamp
- NA1.36-1.25 condenser
- Green Color filter
- NA0.9/0.25 condenser
- Stage upward Stopper
- Power supply: AC 115V/230V
Pros and Cons
While new users may have difficulties how to
use/switch the two sets of objectives to observe different types of specimen, this OMAX 40X-2500X Microscope is a superior quality microscope with a variety of features
that make it suitable for a number of uses in various fields.
Some of the major
strengths of the microscope include the fact that it allows for a high
magnification range for observing a wide range of specimen, has corrected objectives,
which not only allow for clear images, but also a longer working distance as
well as a super speed 18MP USB 3.0 digital camera that can be used for
capturing clear still images, recording live video and making any necessary
manipulations if necessary.
With these and other features, this robust OMAX microscope proves superior in comparison to a number of other microscopes in
Apart from being the ideal microscope for clinical, veterinary, and research purposes, it is also an ideal microscope for educational purposes particularly due to the fact that it can be connected to a PC, allowing for sharing while the Siedentopf allows for a number of students to observe the specimen while changing the eyepiece distance without affecting focus.
