Microscopes are made up of lenses for magnification, each with its own magnification powers. Depending on the type of lens, it will magnify the specimen according to its focal strength.

Thanks much for this. We just did microscopy as a topic and the write-up has really helped me to understand better. Thanks again

Thanks very much dear and please continue doing so, am Gerald M from Uganda East Africa doing diploma in nursing at Mulago school of nursing and midwifery

When compressed air enters or contacts your body, you put yourself at risk of significant health complications. Here are a few examples of the dangers of compressed air:

The optical parts of the microscope are used to view, magnify, and produce an image from a specimen placed on a slide. These parts include:

In Canada, cleaning with compressed air is not allowed by law, according to the Canadian Centre for Occupational Health and Safety (CCOHS). Alberta, Saskatchewan, Quebec, Newfoundland, and Prince Edward Island have specific laws that state compressed air must not be used to clean clothes, people, machinery, work benches, and so forth

I did NOT like this website sourse. Wanna know why I didn’t like it??? I don’t like it BECAUSE my school wants me to use this website sourse. My new science teacher wants us to answer those 10 questions. I think its pretty dumb. No Offensen to anyne out there, because I am a nice person not a mean one.

Compressed air is powerful and can be dangerous—even deadly—when misused. Air compressors aren’t designed for cleaning, but it’s still common practice to clean the dust and debris from filters, machinery, workshop surfaces, clothes, and so forth using compressed air. To help you understand why you shouldn’t clean with compressed air, we’ll break down the most common risks of cleaning with compressor air.

Ans. Rack stop is included in the microscope for preventing the specimen slide from coming too far up and hitting the objective lens.

Their ability to function is because they have been constructed with special components that enable them to achieve high magnification levels. They can view very small specimens and distinguish their structural differences, for example, the view of animal and plant cells viewing microscopic bacterial cells.

The light is then focused on the eyepiece lens. This lens further magnifies the pre-magnified image coming from the objectives.

Seriously, if i am not grateful, i am lying. This note is really helpeful to me to differet ways to different methology.

A beam of light is passed through the condenser to the specimen. The light transmitted from the specimen enters the objective lens. While passing through the objectives, the transmitted rays are spread so that they appear to come from the bigger objects.

While incorrect diving procedures are the most common cause of air embolisms, there is also a risk of an embolism when compressed air is misused at high pressures. Although unlikely, high-pressure air can be forced into the bloodstream through cuts and abrasions. It is improbable, but why even take the risk?

Ans. The eyepiece, also known as the ocular is the part used to look through the microscope. Its found at the top of the microscope. Its standard magnification is 10x with an optional eyepiece having magnifications from 5X – 30X. Objective Lens are the major lenses used for specimen visualization. They have a magnification power of 40x-100x. There are about 1- 4 objective lenses placed on one microscope, in that some are rare facing and others face forward.

Compressed air, especially from commercial air compressors, can exert extremely high forces that turn small particles, nuts, bolts, washers, and other bits into high-velocity projectiles. These objects become shrapnel and can cause severe damage if they hit someone. Even dust and dirt will cause skin abrasions when there is sufficient force behind them—it’s just like sandblasting.

Ans. The magnification of a lens is defined as the ratio of the height of an image to the height of an object. Microscope magnification measures the total enlargement of the image of an object. Magnification power is the product of eyepiece lens power and objective lens power.

Thanks alot of your help and knowI can draw it well in my exams and write the functions.Thankyou very much for your help

Some laws in Canada and the United States govern the use of compressed air and, in many cases, it is illegal to clean with compressed air.

Ans. The coarse adjustment knob moves the stage up and down to bring the specimen into focus. The fine adjustment knob brings the specimen into sharp focus under low power and is used for all focusing when using high-power lenses.

Other legislation may be applicable in some states, provinces, and countries, so you should always check your local jurisdiction for relevant information. When in doubt, use common sense, and do not use compressed air for cleaning!

Thanks a lot for this wonderful note: It is really helpful, Really appreciate the way all the detail about microscope have been explained

this is a really good artical i used it to study my science i just wanted to point out to you that tere are a few spelling errors but other than that it is a 100% rating from me

Federal regulations in British Columbia, Northwest Territories, Nunavut, and the Yukon ban cleaning with air due to the risk to workers, although there is some provision for using low noise emitting nozzles with pressures below 10 psi (70 kPa).

Thank you for the support u have done may the Holy Spirit from the Almighty shine upon you to have more knowledge 2 continue making more notes from various topics in microbiology????✍️

Thanks for helping me to know the parts and functions of a light microscope. THANKS AGAIN AND I HOPE THAT I WILL DRAW IT IN MY EXAM

Microscopes are generally made up of structural parts for holding and supporting the microscope and its components and the optical parts that are used for magnification and viewing of the specimen images. Modern microscopes have additional electronics and display devices. This description defines the parts of a microscope and the functions they perform to enable the visualization of specimens.

it very good website i use in 4 grade right after i plai amog us and they vote me out using orang strat witch mad me sad 🙁

Thank you very much it really helped me with my science home work since i in 8th grade and this my home work to draw a microscope label all the parts and the function thank may the holy father of holy spirits bless you and give more wisdom thanks love you all keep up the good work and thank you again bye.

1. which objective lens focuses closest to object 2. what controls the light entering the binocular lenses 3. how can you enhance the resolving power of a microscope 4. what is useful and false magnification PLEASE CAN YOU HELP ME IN ASWERING THOSE QUESTIONS

Ans. Condensers are lenses that are used to collect and focus light from the illuminator into the specimen. They are found under the stage next to the diaphragm of the microscope. They play a major role in ensuring clear sharp images are produced with a high magnification of 400X and above. Abbe condenser is a condenser specially designed for high-quality microscopes, which makes the condenser to be movable and allows very high magnification of above 400X. High-quality microscopes normally have a high numerical aperture than objective lenses.

In the United States, Occupational Safety and Health Administration (OSHA) regulates workplace safety. Compressed air use is governed by standard 1910.242.b, which states, “Compressed air shall not be used for cleaning purposes except where reduced to less than 30 psi (206 kPa) and then only with effective chip guarding and personal protective equipment.”

There are different types of microscopes like light microscope, dark-field microscope, phase contrast microscope, electron microscope, fluorescent microscope, etc.

Anyone familiar with compressed air used for scuba diving also knows about the potential for air embolisms. Embolisms are a condition in which air bubbles enter the bloodstream and block blood vessels or arteries, with the potential to cause paralysis, induce a coma, or even cause death.

Having been constructed in the 16th Century, microscopes have revolutionized science with their ability to magnify small objects such as microbial cells, producing images with definitive structures that are identifiable and characterizable.

Microscopes are instruments that are used in science laboratories to visualize very minute objects, such as cells and microorganisms, giving a contrasting image that is magnified.

Thank you so much for the note that you have given to me i was so grateful to know that you are so bright people that extend your help to a student
