Description (Features)



Microscope Head

The OMAX 40X-2000X Infinity Trinocular Metallurgical Microscope comes with a rotatable trinocular siedentopf head, which presents a number of advantages to the user. Unlike the sliding binocular head, adjusting the interpupillary distance on a siedentopf head involves turning the eyepiece tubes about a central axis.

The central axis has a scale that allows the user to note and remember the interpupillary distance in the future without much difficulty. This means that all the user has to do the next time he/she is about to use the microscope is set the interpupillary distance using the appropriate scale.

One of the biggest advantage of the siedentopf head is that the tube length does not change with alteration in the interpupillary distance. Therefore, focus does not change even as the interpupillary distance changes.

 

the siedentopf head is especially useful in cases where the microscope is being used by multiple users or students. In such cases, they can continually adjust the interpupillary distance without affecting the focus.

 

The head of the OMAX 40X-2000X Infinity Trinocular Metallurgical Microscope is also inclined at a 30 degree angle and can be rotated 360 degrees. The 30 degree inclination of the microscope makes it easier and more comfortable to use the microscope when seated given that the user does not have to strain the neck.

In addition, the fact that it can be rotated 360 degrees means that the user or multiple users can use the microscope without the need to turn the entire device. In this case, users would only have to turn the microscope head to view the object. 

Trinocular head - The microscope comes with a trinocular head, which allows for a camera to be attached. Here, a camera or C-mount adapters can be easily attached on to the third tube for imaging.


Illumination and Optics


Optics


The OMAX 40X-2000X Infinity Trinocular Metallurgical Microscope comes with a wide magnification range of 40x- 2000x (40x-80x-100x-200x-400x-800x-1000x-2000x).

It offers eight levels of magnification that allow for users to view and investigate a range of objects. Different types of objects/sample require given levels of magnification for specific details to be observed.

With eight levels of magnification that the OMAX 40X-2000X Infinity Metallurgical provides, users have the opportunity to observe and study a variety of objects. For instance, whereas certain minerals require 40x magnification for good viewing, some minerals and metals require 40x and 100x.

The microscope comes with a set of wide field WF10X/20 and WF20X eyepieces and infinity-corrected plan field achromatic objectives (DIN 4x, 10x, 40x (spring, WD 2.8mm), 100x (spring, Dry, WD 0.7mm). Unlike the other eyepieces, wide field eyepieces have a larger lens opening which not only make it easier to position ones eye when viewing, but also widen the field of view which means that the user does not have to move the sample often.

As mentioned, the microscope also comes with infinity-corrected plan field achromatic objectives. As achromatic objectives, they are corrected for spherical aberration for green and bring red and blue light to a common focus.

As plan objectives, the objectives produce flat images in the field of view. Plan achromatic objectives therefore correct lens curvature resulting in clear images when the sample is in focus.

Lastly, being infinity corrected allows the objective to provide long working distance. This also enhances imaging given that infinity corrected objectives allow for optical components to be placed in the optical path.  The nature of the objectives therefore make it possible for the microscope to produce crisp clear images.

100x dry objective does not require the use of oil immersion. It offers the user a longer working distance when viewing the sample. Here, it is worth noting that the sample does not come in contact with the objective lens as is the case with oil immersion.


Illumination

 

EPI Illumination System

 

The OMAX Infinity Trinocular Metallurgical Microscope comes equipped with an EPI illumination system for viewing opaque objects. This system consists of a 6V/30W halogen bulb, a built-in condenser, iris aperture diaphragm and iris field diaphragm as well as 2 color filter slots and polarizer/analyzer slots.

Whereas the light source produces the required light, the filters serve to narrow the wavelength of the incoming light thereby only producing the wavelengths that is ideal to excite the sample.

Here, the 40x and 100x objectives allow users to inspect rough surfaces using the microscope. This is because the two magnifications allow for a longer working distance.

For this system, it is also possible to not only adjust the position of the illuminator, but also the intensity to make ideal adjustments that will produce the best images. This is through adjusting the iris aperture condenser and field diaphragm.


Transmitted Illumination

 

Apart from the reflected system (also referred to as Epi-illumination system) the microscope also comes equipped with a transmitted illumination system that allows the microscope to be used as a normal compound microscope.

The system is composed of a 6V/30W halogen bulb, iris aperture diaphragm and a condenser. In light microscopy, this method is typically used for viewing the morphological traits of the sample/specimen given that light is able to pass through the specimen. Light passes through the condenser and through the sample before reaching the objectives for magnification.

While this method is often used for viewing transparent samples, it can also be used for translucent specimen. This makes it ideal for biological samples.

Other features of the OMAX Infinity Trinocular Metallurgical Microscope include:

  • Abbe NA1.25
  • Rack/pinion focus adjustment
  • Triple layer mechanical stage  A Revolving quadruple nosepiece
  • Color filter holder


Mechanical Stage

The microscope also comes with an impressive triple layer mechanical stage and opaque metal plate for reflected light as well as transparent glass plate for transmitted light.

When viewing opaque objects like metal and certain minerals, the opaque metal plate is used given that light does not pass through the object. However, a transparent glas plate is used when viewing thin, transparent specimen. This allows light from beneath the stage to pass through the specimen into the objectives.

Using the control knobs, the stage can be easily adjusted, moving the stage back and forth as well as sideways without the need to touch the specimen or the sample. Here, the stop lever serves to protect both the sample and the 100x objective from damage.


14MP Digital Camera

The microscope also comes with a true color 14M digital camera that has been designed to capture both still images and record live video. The camera consists of a 0.5x reduction lens and is capabe of 1.8fps at 4096x3288.

In addition to the camera, the microscope also comes with a user friendly software that is compatible with Windows XP/Vista/7/8/10, Mac OS and Linux operating system. This basically means that the microscope and the attached camera can be used with most of the PC operating systems out there.

The software can be easily installed and offers the user advanced features such a Extended Depth Focus that allow for great recording, editing and measuring.

 

Once attached on the third tube of the trinocular head, the user simply connects the microscope to the PC using a USB cable and has the freedom to view the sample up-close on the monitor. This is particularly ideal when more than one person is viewing the sample.

Using the software, users can also make notes, make measurements of angles, lengths and areas.

Some of the most important features of the camera include:

 

  • A reduction lens - the 0.5x reduction lens produces a larger field of view when viewing the sample. This allows the user to get a clear view of a larger area under investigation
  • Sensors
  • A recording system
  • A scan mode

  • G sensitivity


Conclusion




The OMAX Infinity Trinocular Metallurgical Microscope is not only a powerful device, but also a versatile microscope that comes with such excellent features as high quality optics and a large magnification range. It can be used for a variety of activities ranging from biological use to investigating metal surfaces, which makes it the ideal microscope for all users.


With the high quality optics and a great camera in place, users are assured of high quality images when using the microscope. It is therefore a great device worth checking out for your metallurgical needs.
