digital imaging device
- Infinity-corrected plan
field achromatic objectives
Trinocular Siedentopf Head
As the name suggests, the microscope has in
place a trinocular head composed of a binocular eyepiece and a camera tube.
Having a trinocular head presents a big advantage for users given that users
have the freedom to both use a monitor to view the sample through a camera
attached to the third tube as well as the freedom to use the binocular eyepiece
without much difficulty.
Microscopes that only come with a monocular eyepiece
or binocular eyepiece only allow the user to either use a monitor to view the
sample (through the attached camera) or use the eyepiece.
The Omax Infinity Trinocular
Metallurgical Microscope presents a significant advantage as both can be used for viewing. This is particularly beneficial in class or when
making presentations. The user can use the binocular eyepiece to
focus the sample while at the same time showing the audience what he is examining through the
The trinocular head makes the microscope easier to
use particularly for new users. There is no need to remove the eyepiece to connect the camera.
In addition to the trinocular head, the
microscope uses a siedentopf head, which is easy to operate and adjust. One of the biggest advantages of the siedentopf head system is that
users can adjust the interpupillary distance without affecting the tube length.
As such, the user does not have to keep adjusting focus whenever they adjust
the interpupillary distance.
The siedentopf head is also commonly referred to as a
"compensation-free system" as users do not have to manually
compensate for the changes to the tube length. In this case, users may see the
term "compensation-free head" being used instead of a
"siedentopf-head". In such cases, new microscope users should
remember that they have the same meaning.
Omax Infinity Metallurgical Optics and Illumination
The microscope comes with three types of
eyepieces including the wide field WF10X/20, WF20X and WF25X. These allow the
user different magnification powers in that they can interchange the eyepieces
depending on their needs and the type of sample being viewed.
Having wide field eyepieces presents a big advantage for two main
reasons. The first advantage of wide field eyepieces is that they come with a
wider opening, which makes it easy for users (especially kids) to position
their eye and observe the sample. Secondly, and most important, wide field
eyepieces allow for a wider field of view allowing the user to view a larger
In addition to the wide field eyepieces, the
microscope also comes with infinity-corrected plan field achromatic DIN
objectives (4x, 10x, 40x (Spring, WD 2.8mm), 100x (Spring, Dry, WD 0.7mm)).
These standard objectives provide maximum resolution as well as flat-field
viewing on expandable platforms. In addition, they significantly reduce effects
commonly associated with chromatic and spherical aberration.
As DIN objectives,
they can also be used on a majority of common microscopes given that they are
standard objectives. Users are therefore assured of high quality images when
using the Omax Infinity Trinocular Metallurgical Microscope due to its high quality optics.
Together with the wide-field eyepieces, the
objectives used for this microscope offer ten levels of magnification
(40x-80x-100x-200x-250x-400x-800x-1000x-2000x-2500) which is a wide range. Iit allows users to observe a wide range of samples. The 100X spring
objective used for this microscope does not require immersion oil when viewing
some samples. It is for this reason that it is referred to as the 100x dry
objective. Regardless, users still get high quality images of the object.
The Infinity Trinocular Metallurgical Microscope
is an upright microscope, which means that the objectives and the eyepieces are
above the microscope stage. Here, EPI Kohler halogen reflected illumination is
used for illuminating the sample. The system is composed of an aperture iris
diaphragm as well as an iris diaphragm, which position the light.
worth noting that reflected light microscopy (epi-illumination) is typically
used for viewing opaque samples (metal, minerals, ceramics etc). The objectives
therefore serve a dual function in that light passes through them to the sample
and collect light that is reflected off the sample.
The illumination system uses halogen bulbs, which
use a tungsten filament and halogen gas. While halogen bulbs produce a lot of
heat, this is not a big issue given that the microscope has a bulb housing. The
two color filters help regulate the light in order to produce sufficient amount
of light depending on the sample under investigation.
Other important features of the microscope
- Built-in condenser
- Built in, spiral
- Coaxial coarse and fine
knobs focus mechanism on both
sides of the microscope
- 110V 50Hz/60Hz power supply
degrees inclined 360 degrees rotatable microscope head
- Revolving quadruple nose
- Mechanical stage (15cm -
14cm, translation range 50mm x 75mm)
Triple Layer Mechanical
The microscope also comes with a triple layer
mechanical with an opaque metal plate. As such, it does not have an opening at
the centre as light does not pass through the sample. However, it also
comes with a transparent glass plate for transmitted light. This allows for the
microscope to be used for viewing samples that allow light to pass through. The coaxial coarse and fine knobs located on both sides of the microscope with
adjustable tension are used to control the stage.
As previously mentioned, the Omax Infinity
Trinocular Metallurgical Microscope comes with a trinocular head. The third,
upright tube located in front of the binocular eyepiece allows for a camera to
The digital camera is a true color 2560x1922 pixels (5M pixels)
that also comes with a 0.5X reduction lens. With the Super speed USB 3.0
connection, the system allows user to capture real time images and videos of
high quality. The 0.5X reduction lens on the camera provides a larger field of
view, which allows users to view a wider field of the sample thereby getting to
study the sample better.
The camera system also comes with a user
friendly software that is compatible with various Windows OS, Mac OS X and
Linux operating systems. This software can be easily installed and allows the
user to capture still images, record videos, make measurements and edit images.
Users can capture images at excellent speeds (14.2fps at 2560x1922,
38.3fps at 1280x960, and 101.2fps at 640x480)
The Omax 40X-2500X Infinity Trinocular Metallurgical
Microscope is an excellent device that comes with a number of outstanding
features that will be of great benefit to the user. In addition, it is easy to
use and users can use it for a variety of applications due to its versatility.
It's a quality microscope worth checking out for a
variety of applications including research and examination of objects such as metals, crystals and electronic circuits among many others.
