Microscopes and their Types

For instance, microscopes are used in various areas, so there are different types of microscopes used in every specific field:

• Stereomicroscope

• Compound microscope

• Inverted microscope

• Metallurgical microscope

• Polarizing microscope

Stereo Microscope

In zoology there is the term entomology (which examines the insects) in this field, these stereo microscopes are used. The enlargement level of these stereo microscopes ranges from 10x to 40x the stereo microscope can give people three-dimensional results. Every stereo microscope is a simple microscope as it provides observation at a relatively low level.

This microscope can produce the result of the transfer and reflected light. It can also be used to see a specimen that does not permit the illumination to pass through. Examples of objects a stereo microscope can provide are plant life, circuit boards, metal parts, etc.

Compound Microscope

A compound microscope provides images that are in two dimensions. Although, when we compare the stereo microscope with the compound microscope we can see that the compound microscope provides a higher magnification of about 40x to 1000x the stereo microscope. It is a powerful microscope.

As the name implies, these are used in hospital labs, pathology, schools, etc. A compound microscope always gives us the advantage to see a variety of objects that includes bacteria, onion skin, blood cells, tissues, etc.

Inverted Microscope

Another term for inverted microscopes is metallurgical microscopes or biological inverted microscopes. In this microscope, to view a species, a Petri dish is used. A species used in the biological inverted microscope is mostly living.

An inverted microscope can give us an enlargement level of about 40x to 400x. These microscopes can be used in research to evaluate, red cells, tissues in a specific living cell, microbiology, etc.

Metallurgical Microscope

They are high powered microscope which contributes the embroidering of about 50x to 200x but from off and on it contribute 500x embroidering. In a metallurgical microscope, the light passing is indicated regarding the objective lens. It is used to decipher very minor objects that are up to micro-level ruptured in any ore, grains, liquid materials which have very floating surfaces, etc.

Industries that are related to aircraft, transportation manufacturing industries, etc also use this microscope.

Polarizing Microscope

Polarizing microscopes serve many basic functions hence they are used day after day. These microscopes are also used to detect whether a crystal is positive or negative. Chemical microscopy is a field in which polarizing microscopes are used. Chemists also use these types of microscopes, earth scientists, and in the medication field.

As other microscopes avoid lights to pass on, in a simple microscope, a polarizing microscope allows a precise light to pass on while the other waves are reflected in this. In short, it is an instrument that uses passing on characteristics of light on different objects like amorphous structures, to build an image.

Celestron 44340 LCD Digital LDM Biological Microscope

I am a keen natural historian who is just getting into the study of mosses and bought this scope hoping it would help me identify an increased range of species. I had read good reviews from varied users.

The plus points of the scope are its price, and the ability to easily store images. I am getting pretty good images of leaf structure, cells, and spores in mosses and was able to make a transparent acetate overlay with a scale on for the screen to help me measure small dimensions - a bonus. In this respect, it has fulfilled my wishes. Unexpectedly, I was able to use the scope to look at protozoa from my pond. For this group of very small animals and plants, I was able to make identifications to genus level. Videoing these tiny things was an unexpected delight and the vids posted on Facebook elicited a surprisingly large and enthusiastic amount of feedback.

The downside is that it does not replace the requirement for a dissecting binocular microscope for specimen preparation (using it has brought home how critical a good slide preparation is for even a half-serious student). In addition, I suspect that the optics are not as good as a decent compound microscope. One design fault is its lack of sturdiness (easily knocked over), which in combination with the digital shutter button (a bit temperamental) means that camera shake can spoil some images. Another is the fact that the stage has a relatively limited amount of movement, and both the stage control screws are on one side, so you can't move up and down at the same time (ie like an etch-a-sketch) - useful when chasing protozoa across the screen. Also, the above-stage illumination is pretty useless for something as 3-dimensional as a small plant, as very little of the subject can be brought into focus, even on the smallest magnification (x40). It would be fine for 2-d things though, like stamps.

I am going to have to buy at least a dissecting microscope to take my studies forward, and may one day also trade this in for a good compound scope. However, it has really catalyzed my interest in microscopy again (those videos of protozoa are fantastic!) and is a superb purchase for kids/families / GCSE. If you get it, for this reason, don't forget to get a pack of slides and a pack of coverslips too to make your own slides. You'll get fed up with the sample provided in under 5 minutes.

AmScope Optical Glass Lens All-Metal LED Compound Microscope Review

AmScope optical glass microscope is built for children from 8 years and up. It runs on batteries and low voltage wall power for children's safety. The microscope is user-friendly, and the dual focusing control knob makes it more convenient. It also contains two eyepieces for wide angles and better vision.

The microscopes make and made are strong and robust. It comes with a solid metal frame with an enamel finish that resists any stains. All mechanical components are made of metal.

The sturdy structure allows the microscope to stand firm on the surface, and you may have a shake-free view every time. The microscope contains magnification powers that allow you to magnify up to 1000x.

The eyepieces provide an expansive vision with full optical glass elements. High-resolution images give the user a better and more accurate view. Rotatable monocular headset on 45 degrees inclined 360 degrees. It helps to examine the specimen on a sharing basis, and 45 degrees angle helps to resist any eyes and neck strain.

Manufactured under ISO 9001 quality control standard and AmScope provides a five-year warranty. Single lenses condenser and disc diaphragm with dual focusing control knobs help in in-depth research.
