The OMAX 5MP Digital 40X-2500X Advanced Oil Dark field Trinocular Compound LED Microscope is a versatile product
that comes with a number of excellent features aimed at ensuring great user
In addition to several features that allow for bright-field and dark-field microscopy, the microscope also comes with the following important
- Six levels of magnification
- A 5.0MP true color digital
- Replaceable 3W LED light
The Omax 5MP Digital 40X-2500X Advanced Oil
NA1.25 Dark field microscope is a trinocular microscope, which means that it
comes with a trinocular head. As such, it provides accommodation for a camera
without the need to remove either of the eyepieces.
Having a trinocular head
presents a great benefit in that it allows users the freedom to either view the
specimen through the eyepieces or through a monitor thereby making it possible
to double check or confirm the investigation. Secondly, a trinocular head
allows for sharing.
When more than one person is viewing the specimen, the trinocular
head allows more people to view the specimen on the monitor screen at the same
time. It also comes with a sliding binocular head,
which is easily adjusted by sliding the binocular pair outwards or closer
together. The microscope can therefore be comfortably used by anyone regardless
of their interpupillary distance (2-3/16inch ~ 2-15/16inch (55mm ~ 75mm)).
The viewing head is also inclined at a 45 degree
angle and can be turned around 360 degrees. These features are aimed at
enhancing comfort and convenience. With a 45 degrees inclination of the
binocular head, the microscope can be used comfortably while seating without
causing strained or cramped muscles.
The 360 degrees
swiveling allows the microscope head to be easily turned around to the
direction or the user without having to move the entire microscope. Therefore,
in the event that two users are sitting opposite to each other, they can view
the specimen by simply turning the microscope head to their direction without
moving the entire microscope.
Comfort and enhanced convenience is helped by the presence of diopters in both eyepieces. These are important
features of the eyepiece that allow people with different eye visions to use the
microscope without any problems. Depending on the user's eye vision, the
diopter can be easily adjusted to the ideal position to get a clear view of the
The microscope also comes with wide field WF10X/18 and WF25X
eyepieces that can be interchanged depending on the needs of the user (wide
field eyepieces allow for a wider field of view).
* WF25X provides 25X magnification while WF10x
gives 10X magnification with a field of view of 18mm. When combined with
different objectives, they offer different levels of magnification. They are
thus interchanged depending on the needs of the user.
The OMAX 5MP Digital 40X-2500X Advanced Oil
NA1.25 Dark field Trinocular Compound LED Microscope comes with a set of 4X,
10X, 40X (S), 100X (S, Oil) achromatic DIN objectives. When combined with
either eyepiece, the objectives provide six levels of magnification
Having an achromatic (achromat) lens for the objectives
provides a significant advantage given that they eliminate problematic
chromatic aberrations, which in turn makes them the most cost efficient lenses
for good polychromatic illumination and imaging.
Compared to other simpler
lenses, using achromatic lenses ensures consistently smaller spot sizes as well
as high quality, superior images without decreasing clear aperture.
objectives are also labeled DIN, which means that they are DIN standard (they
provide 160mm distance from objective flange to the flange of the eyepiece).
This means that the microscope uses standard objectives that can be easily
obtained and interchanged in the event of damage. These objectives can also be
exchanged with JIS standard objectives that provide similar optical performance,
equal quality as well as the same RMS mounting thread (0.7965" x 36TPI).
* Using standardized lenses makes it easier to
interchange objectives in case of damage. This is because standardized lenses
are readily available for the microscope when need be.
As mentioned, the OMAX 5MP Digital 40X-2500X Dark field Trinocular is a
versatile device that allows the user the freedom to view a variety of specimen
using two microscope methods (dark field and bright field).
system comes with an NA1.25 Abbe condenser with iris diaphragm and filter
holder and is considered to be the most basic microscopy method. Here, light
from the source under the stage is gathered in the condenser, shaped into a
cone and focused on the specimen plane.
Although bright-field microscopy is
simple, it is an important technique that is used in such fields as
bacteriology and various other life sciences. For this technique, users often
see a dark specimen with a bright background.
The dark-field system on the other hand comes
with an NA 1.36-1.25 condenser. The condenser used for this technique serves to
form a hollow cone of light with light travelling around the objective.
this technique, users observe specimens with a dark background compared to bright-field where the background is bright. However, the specimen appears
brightly lit thereby providing a big contrast with the background allowing for
a clear view of the specimen.
Dark-field microscopy is also useful for
laboratory purposes making it important in microbiology, bacteriology and other
research purposes. Unlike bright-field microscopy, dark-field microscopy is
ideal for viewing unstained specimen that absorb little light ideal for viewing the external features of such specimen as algae,
yeast, hair and planktons among many others.
Some of the other features of the OMAX 5MP
Digital 40X-2500X include:
- Power supply: 100V~240V
50/60Hz worldwide range
- Rack and pinion adjustment
- Black palm rest on the base
- A mechanical
stain-resistant double layer
- Coaxial coarse and fine
focus knobs on both sides
- Tension control
- Photo tube
adjustment range: 5/8inch (15mm)
In addition to a double layer mechanical stage
that can be easily moved back and forth and sideways using the knobs, the
microscope comes with coaxial coarse and fine focus knobs on both sides used
for focusing. This has been shown
to be particularly important features for both right handed and left handed
By having the coaxial coarse and fine focus knobs on both sides, users
can easily focus the specimen without difficulties presented by being either
left or right handed. One of the biggest challenges of having the knobs on one
side is that right-handed/left-handed individuals may have difficulties
focusing (moving the stage) which may result in moving the stage up too fast
and damaging the slide or the objective lens.
5MP Digital Camera
The OMAX 5MP Digital 40X-2500X Advanced Oil
NA1.25 Dark field Trinocular Compound LED Microscope comes with a 5MP digital
camera with a 0.5X reduction lens for a wider field of view. With regards to
frame speed, the camera allows for 5fps at 2592x1944, 18fps at 1280x960, 60fps
at 640x480. This allows the user an option with regards to dimensions.
camera also comes with software that is compatible with all computers using
Windows XP/Vista/7/8/10, Mac OS and Linux operating system. This means that the
camera can be used with virtually all types of computers (PC) given that it is
not limited to a few operating systems (OS). Once installed, the software
allows the user to not only capture images and record videos, but also make
measurements of the lengths, angles, areas and edit the image.
system, the user also has the freedom to capture images and record videos that
can be saved on the PC or shared with others.
