ZEISS 435063-9010-100 Stemi 305 Stereo Microscope

5:1 Zoom, 8x-40x Magnification


Product Overview

The ZEISS 435063-9010-100 Stemi 305 Stereo Microscope is a high performance, compact, Greenough stereomicroscope with 5:1 zoom for biological education, laboratory use as well as production environment use. The ZEISS Stemi 305 comes with a continuous magnification range of between 8x and 10x with fixed zoom click stops positioned at 0.8x, 1x, 2x, 3x and 4x.




In addition to an adjustable, intraocular distance of between 55 and 75mm, the microscope also comes with focusable 10x eyepieces, which provide a field of view of 23mm as well as a working distance of 110m.


Description


The ZEISS Stemi 305 stereo microscope is a type of stereo microscope that uses twin body tubes inclined to produce a stereo effect (Greenough stereo microscope). This is different from CMO stereo microscopes, which use a single Common Main Objective shared between a pair of eyepiece tubes and lens system.

As such, the ZEISS Stemi 305 stereo microscope is ideal for such applications as dissecting biological specimens, printed board inspection and other similar tasks.


ZEISS 435063-9010-100 Stemi 305 Stereo Microscope -  Features and Functions


With its ergonomic design, the Stemi 305 provides a 45 degree angle for comfort during use. The intraocular distance can be easily adjusted to accommodate different eye distance between users while the 10x eyepieces allow for a generous 23mm field of view. This is a wide field of view that will allow the user to observe a wide field and thereby find the point of interest.

It's also equipped with a manually operable zoom of 5:1 and a continuous magnification range of 8x-10x. As such, it offers powerful magnification as well as high resolution, which helps reveal intricate details of the object under observation.

With regards to working distance, the microscope offers 110mm of working distance, which not only allows the microscope to accommodate objects of varying size, but also move or turn the object for more detailed observation. That is so that the large working distance allows for easy specimen handling and a large field of view.



Some of the other important features of the Stemi 305 include:

 

  • integrated power unit 12V DC 24W/100 - 240V AC/50 - 60Hz
  • working surface of D19.5cm x W16cm
  • a compact footprint of D31cm x W20cm
  • A glass plate with diameter 84 mm
  • Near vertical LED illumination and built-in spot LED for bright-field illumination
  • Spiral cable RJ12 Stand K EDU
  • Mount D=76 mm for Stemi mount/Mount S
  • Interface D=66 mm for illuminators
  • Thread M52 for front optics or analyzer

 

Using this microscope, users will get an opportunity to observe the samples as they really are. That is, users will get to observe three-dimensional objects, which are crisp in contrast. Here, the excellent contrast allows for very clear and detailed images of the sample. Given that no preparation is required with the Stemi 305, users will also enjoy the advantage of an easy to use microscope, which comes with integrated LED illumination for both reflected and transmitted light.

 

The Stemi 305 may also be described as an "all-in-one-device". This is because of the fact that this device integrates everything that users need into a single Greenough stereo microscope. All that the user has to do therefore is simply plug in, switch it on and focus.

One of the other major strengths of the microscope is that the integrated illumination is variable, which allows for contrasting different specimens at its best. This simply involves pressing a button in order to combine up to two reflected light contrasts and transmitted light.

With this device, each zoom body is equipped with near-vertical light units for illuminating deepenings in the sample. However, the second reflected light and transmitted lights units are interchangeable. This is important in that it enables predefined microscope sets to optimize contrasts in the application range.

 

The ZEISS 435063-9010-100 Stemi 305 Stereo Microscope uses while LEDs. This type of LEDs generates brightlight of daylight color, which has the advantage of producing crisp and clear images. These LEDs also have a number of other benefits, which include;

  • Long-life
  • Noiseless
  • Maintenance free
  • real energy savers


Pros and Cons


Apart from ease of use, one of the greatest strengths of ZEISS 435063-9010-100 Stemi 305 Stereo Microscope is that it uses a near vertical illumination system with integrated LEDs in near vertical LED position. This is beneficial in that the level of brightness is increased and shadows are reduced. This is particularly ideal for the inspection of holes or depressions on the object under observation.

Moreover, with its excellent features, the device produces crisp and clear images, which enhances the viewing experience of the user.

One of the only minor challenges for some users is that it may initially prove challenging to balance the two lights when trying to optimize contrast. However, after getting used to the device, this becomes an easy task.


Conclusion




In conclusion, this is an excellent device for laboratory use, education and/or object inspection. It comes with a number of excellent features that make it very easy to use, which means that kids would also find it easy to use. With a great working distance and a near vertical illumination system with integrated LEDs in near vertical LED position, the ZEISS Stemi 305 Stereo microscope would be a great purchase that can also be used at home.
