The entire exercise was all about caring for and using the microscope. We performed various activities that enabled us to familiarize ourselves with the parts and uses of the microscope. Using the microscope, we observed different objects such as cotton, silk, hair, and even a letter "e." We viewed it using both the low power objective and the high power objective. We did these activities in order to better understand how the compound light microscope works and also to learn about the different procedures in setting up a slide. The results of the activity made us learn how to operate the microscope efficiently. I found out that the iris diaphragm controls the light and the uses of the LPO and HPO. I also noticed that the view of the object being illuminated is inverted.
LPO- Low power objective
HPO- High power objective
There are a lot of things not visible to the naked eye. What most of us don't realize is that there is a world full of wonders out there; A world full of diversity and "magic." A world called microscopy. It's amazing how one single device called the microscope can let us view things that are too small for the human eye. A microscope has the power to magnify object from 100x to as much as 1000x or higher. In fact, there are many microscopes, each with their own unique capability. Examples of these are the atomic force microscope, scanning probe microscope, and electron microscope. Microscopy is the technique in which a person is able to view images of structures that are too small for the naked eye. In light microscopy, light is reflected through a series of lenses that eventually illuminate the object being seen.

...th the different parts and uses of the microscope. I conclude that compound light microscopes give inverted images of the object because of the reflected light; and that the passage of this light is controlled by the iris diaphragm. I also conclude that each part of the microscope is significant for it to function properly and effectively.

- Visual light microscopy provides a relatively inexpensive and quick way for someone to observe features in a sample such as layer shift in composites, porosity in ceramics, or cross sectional views for welding. In fact, VLM is often a go to means for engineers and scientists to examine the microstructure of materials. Unlike other processes such as scanning electron microscopy (SEM) there is no requirement for sample preparation beyond using slides or hot/cold mounting procedures along with relatively simple grinding and polishing procedures....

- Scanning electrochemical microscopy (SECM) is a technique that is part of a broader range of techniques that are commonly referred to as scanning probe microscopy. It has a wide array of applications in chemistry, biology, and even the material sciences. SECM uses a ultramicroelectrode to measure the local electrochemical behavior of a substrate in a solution. When introduced, the ultramicroelectrode acts as the electron conductor in the substrate and the added electrolyte acts as the ionic conductor in the solution....

- Electron Microscopy and the Study of the Cell Electron Microscopes have revolutionised today’s understanding of the cell. In 1838 Scheleiden, a botanist theorised that the basic unit of a plant was a cell, the following year the scientist Schwann came up with a similar hypothesis this time related to animal cells, their combined ideas gave us the cell theory, the idea that all living things were made from similar building blocks, cells. It took 100 years before this idea was confirmed with the invention of the electron microscope.... [tags: Papers]

- ... These waves don’t end abruptly at a wall or a barrier, but taper off quite quickly. If the barrier is thin enough the probability function may extend into the next region, through the barrier. Because of the small probability of an electron being on the other side of the barrier, given enough electrons some will indeed move through and appear on the other side. When an electron moves through the barrier in this fashion.

- Introduction: Scanning probe microscopy in nano mechanical testing has started with the invention of the scanning tunneling microscope in the year 1981. Till then based on the type of principles there are number of models developed and are in use. Scanning probe microscopy found popularity owing to its ease in versatility in dealing with a number of issues, typically it is used to identify the material properties on nano to even pico scales. Scanning probe microscopy techniques such as atomic/friction force microscopy(AFM/FFM) are increasingly finding applications in tribological studies of engineering surfaces as well for finding surface texture etc....

- Mass-Observation, Microscopy, and the Everyday The everyday is an assimilation of fragmented happenings that are interwoven to manifest society. A general stereotype of society can not be drawn from a single fragment, but must be created through an examination of the relationships between individual pieces. Every fragment, no matter how banal, contributes to the understanding of the everyday. In order to study the everyday, the use of microscopy and Mass-Observation are essential because they provide a way of viewing the everyday in a way that is unfamiliar.... [tags: Essays Papers]

- Confocal Microscopy Lab Confocal microscopy uses a laser that produces excitation light. This laser light reflects off of a dichroic mirror and then the laser light hits two mirrors that are mounted on motors. The mirrors then scan the laser light across the sample. Dye that is found in the sample then fluoresces (Weeks, 2003). Filamin was labeled with a red fluorescent label rhodamine (TRITC) and actin was labeled with the green fluorescent label fluoroscein (FITC) which was conjugated to the actin-binding fungal toxin phalloidin....

- Electron Microscopy Investigation The electron microscope was first made when biologists found a problem with the resolution of a light microscope. Resolution means “the ability to distinguish between two points”; the problem is that the maximum resolution of a light microscope is 200nm. So if two points are closer together than 200nm they are seen as one. One example of this problem is that under a light microscope the centrioles in an animal cell appear as one, however when viewed under an electron microscope we can see that there are two centrioles at right angles to each other....

- Introduction Our paper in a nutshell: Photo-Activated Localization Microscopy, or PALM, allows an unclear picture of a tiny protein to be seen as a precise dot. Essentially the PALM process begins with recognizing a field of proteins in a cell, which appear as unfocused,"fuzzy" specks. There are too many protein 'dots' in a single region to use mathematical equations alone to figure out exactly where they are located, though by picking out a few proteins at a time, complex equations can be used to determine where the proteins are located in the cell....
