Features (Description)


 

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 monitor.

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



Optics

 

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 field.

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.


Illumination

 

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.

It is 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 include:

 

  • Built-in condenser
  • Built in, spiral adjustment condenser
  • Coaxial coarse and fine knobs  focus mechanism on both sides of the microscope
  • 110V 50Hz/60Hz power supply
  • 30 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.

 

Camera Attachment

 

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 be attached.

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)


Conclusion




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.
