OMAX 40X-2500X Touch screen PLAN Infinity Trinocular Siedentopf LED Compound Biological Microscope
In addition to a 5MP digital camera and a 9.7 inch touch screen display, some of the other important aspects of the microscope include:
- 4 PLAN infinity achromatic objectives
- Wide field WF10X/18 and WF25X
- Six magnification levels
- A back slot for holding and carrying the microscope
The OMAX 40X-2500X Touch screen PLAN Infinity
Trinocular Siedentopf LED Compound Biological Microscope has a sturdy
design that is worth mentioning. The body frame of this device shows creativity
particularly when considering the specially designed slot at the back of the
stand for easy holding and carrying. This makes it easier to
hold or move the microscope which is 50cm x 41cm x 20cm in dimension and 17 lbs
(7.7kg) in weight.
This OMAX Compound Biological Microscope comes with a
Trinocular Siedentopf viewing head, which has a number of advantages.
trinocular head, users have the freedom to use the third tube to connect the
monitor for viewing or users can simply remove the monitor and
connect a camera that can then be connected to a bigger monitor or a computer
if need be. Therefore, users do not have to remove one of the eyepieces for
The trinocular viewing head also allows more than one
user to view the specimen given. This becomes particularly beneficial for
explaining the specimen to students or making presentations.
The other advantage here is the Siedentopf binocular
head. In addition to being easier to use (by simply turning the eyepiece tubes
about a scale axis) the Siedentopf head can be adjusted repeatedly without
For kids, this is a great feature given that they can change
the interpupillary distance as much as they need to without changing focus. As
such, it becomes easier and more convenient to use compared to a microscope
with a sliding viewing head where focus changes with every adjustment of the
Comfort of use is also enhanced by the rotatable and inclined
Siedentopf viewing head. The 30 degree angle of inclination makes it easier and
comfortable for users to view the specimen while seated. This keeps users from
having to strain to view the specimen thereby preventing or greatly minimizing
risks of strained neck muscles.
The Siedentopf viewing head
can be rotated 360 degrees. When viewing the specimen through the binocular
eyepieces, this becomes particularly convenient when several people are viewing
the specimen. Rather than turning the entire microscope, users seated opposite
to each other can simply turn the Siedentopf head to their direction to view
The Siedentopf viewing head also comes with a
pair of wide field WF10X/18 and WF25X eyepieces. Wide field eyepieces allow for
easier viewing due to a larger lens opening. On the other hand, having
two types of eyepieces will allow the user to interchange eyepieces as needed
depending on the specimen being used given that each type will result in
The OMAX 40X-2500X Touch screen PLAN Infinity comes with four high
quality PLAN infinity achromatic objectives (4X/0.10, 10X/0.25, 40X/0.65
(spring), 100X/1.25 (spring, oil)). When combined with the eyepieces, these
objectives provide six levels of magnification ranging from 40X to 2500X
The PLAN infinity objectives also have a
number of advantages that include:
- Longer working distance -
infinity corrected objectives are meant to be used with the infinity corrected
tube. They provide a longer working distance compared to other typical
standard objectives. With this, the lens system includes the tube, which
allows for the objective to be further away from the specimen under
investigation. This in turn allows for more space for the specimen to be moved
- Plan objectives have a
significant advantage given that they correct for better color and spherical
aberration and they allow for a flat field (about 95 percent of
the center of the image). So, they are much better compared to both
semi-plan and achromatic objectives.
Some of the other features include:
- An adjustable photo tube
- Double layer X-Y mechanical
stage with scales
- Power supply: AC 115V/230V
(switchable), 50/60Hz, US and Canada plug version
- Coaxial coarse and fine
focus knobs on either side with tension control
- 3W LED Lamp
- Intensity adjustment
- Advanced 0.9/0.25 NA
flip-top condenser with iris control - for improved image quality
- Stage upward stopper -
designed to stop the stage at a given point to prevent the objective and
microscope from getting damaged.
For this microscope, light is transmitted, which
means that it passes through the specimen. This makes it possible to view the
internal structures of the specimen (cells, organelles etc).
also uses a 3W LED lamp, which has a number of advantages. Some of these
advantages (when compared to other light sources like halogen bulbs) include a
longer life span, they use less energy, they produce no heat and none or very
little color change over time.
In a binocular microscope, a light beam is split
into two before arriving at the eyepieces and to the eyes. However, this being
a trinocular microscope, there is a moving prism system that allows for light
to be directed towards the binocular as well as the third attachment tube for
the camera. Therefore, the microscope has in place a lever that can be used to
switch light towards the binocular or the camera.
Depending on how the
microscope is being used, the lever can switch the beam to the photo port or
100 percent to the eyepieces in the event that the photo-tube is not in use.
This therefore allows the user the freedom to direct beams to either the
eyepieces or the photo-tube or only to the eyepieces depending on their needs.
The Digital Display System
This OMAX 40X-2500X Trinocular Microscope comes with a digital display system that consists of a 9.7 inch Color LCD Touch Screen and a camera (5MP) with a 0.37X adjustable reduction lens.
Once connected, the user can simply view the specimen on the 9.7 inch Color LCD touch screen that is attached on the photo-tube. An adjustable reduction lens also allows the user to adjust the field of view to view the specimen or given points of the specimen as they desire.
The system (works on Android 4.2.2 operating system) connectivity can be achieved through the following:
- HDMI cable
- USB 2.0
Using this system, users can easily use the operating system to capture still images, record videos and transfer them to a PC for storage or sharing. This system makes it easier for the microscope to be used for teaching and presentations.
