Magnification

SEM is a kind of microscope to observe the topography of materials. SEM has some advantages: it has a large depth of field and we can observe the 3D image of the sample and analyzing its topography, its magnification range is widely and we could make sample easily because of the X-ray spectrometry, which can determine the elements of sample. When electron beam attack the sample, incident electron will be diffracted and change the direction or even loose some energy. During this process,…

treatment by using the index of effectiveness. The microsture of the best and bad treatments milk candy were presented in Figure 1. Figure 1. Microstructure of milk candy. (A) the best treatment and (B) the bad treatment. (1) magnification 1500x and (2) to 2000x magnification. Figure 1 showed the spread protein matrix and fat globules in the best and bed treatments of milk candy. Figure 19 (A1) and (A2) showed the more compact and relatively evenly spread of protein matrix with the…

CHAPTER 4 RESULTS AND DISCUSSION 4.1 Incomplete Carbon Glucose Preparation for sulfonated solid acid catalyst must undergo a process which is called carbonization or pyrolysis. Glucose is natural organic compounds had been used as starting raw material because it is cheap and less toxic. Carbonization is an important step before the sulfonation process because it will form amorphous carbon composed of small carbon sheets [B] and produced sites for sulfonic group to be attached or…

The formula for magnification is M=(fo/fe), where fo is the focal length of the objective lens, and fe is the focal length of the eyepiece. This means the size of an image is proportional to the focal length of the lens. So the longer the focal length of the objective lens, or shorter the focal length of the eyepiece, increases the magnification. In refracting telescopes, the objective lens will always be the largest lens of the…

For many shooters the parallax problem is negligible due to very low magnification and shorter distances. Much like the red-dot military style scope, they are generally parallax free. Even for some middle power rifle scopes, due to lack of range may have little parallax. A lack of parallax may also be noticed on some tactical…

on the slides because they penetrated and bound only to the structures in neuron cell bodies. There are two uses for the Nissl stain method when looked at through high and low magnification. Under low magnification you can see the brain structure by selectively staining groups of cell bodies whereas under high magnification, when using the Nissl stain, it allowed them to get a good indication of how many neural cell bodies were in an area because they could now count the number of stained dots…

this lab I examined and drew different samples of slides and then categorized these slides into a logical evolutionary order. The first sample that most likely came first in the evolutionary order is the typical bacteria, which I viewed at a 1000 magnification. These bacteria can be found in the Eubacteria domain and kingdom. The bacteria in my sample were coccus, which means that the bacterium has a round shape, and this type of bacteria is one of the simplest forms of bacteria. These cells are…

instrument that keep observe specimen in resolution and magnitude way. However, there are some microbes such as viruses that cannot be observe by certain microscope and this microbes has to be observe using electronic microscope which has more magnification power. In this experiment, light microscope has been used to determine and observe the microbes by using scanning lens (4x), low power lens(10x), high power lens(40x) and immersion-oil lens(100x). There are several function of microscope…

historically used to identify samples of interest such as bacterial biofilm, microtexture surfaces, and even cancer cells for diagnosis.[1, 2, 3] The first high magnification SEM was reported in a journal in 1938 by Ardenne after developing the instrument after conceptualization; this instrument was novel for the time as it achieved magnification in an incomparable way to other traditional methods available at the time and eliminated the loss of light due to dispersion (chromatic distortion).[4]…

levels of magnification. The coatings also reduce glare and reflection and help protect the external surfaces of the glass from scratches. The scope is sealed, making it waterproof and fog-proof. This lets you take your rifle hunting in any weather or in the misty early mornings without worrying about condensation. The eye relief of this Bushnell model is 3.7 inches. This gives your AR223 plenty of room to recoil without contacting your eye socket. The exit pupil is 13.7 mm at 3x…
