Buying Guide: What to Consider When Select Microscope:
One thing that you’ll definitely have to consider when buying a microscope is the price. Generally, if you are looking to buy the best microscope for kids, you will often see microscopes that cost between $80 and $200. You should plan to spend this amount if you want to get a microscope of decent quality. Some microscopes even cost up to thousands of dollars, but unless you are buying a microscope to view organisms you won’t need to spend up to that.
There are lots of microscopes made of plastic and so many are made of quality metal. Most of these plastic microscopes are inferior when it comes to structure, which means they are prone to damage and they give inferior optical quality.
The best way to avoid this is to buy your microscope from a reputable vendor and make sure you are buying one made by one of the best microscope brands. Sturdiness must be considered when buying a microscope. It must be solidly constructed and made of a sturdy metallic allow. A microscope with a strong construction would possess a certain degree of durability and will last longer than a microscope made of plastic.
Most microscopes come with a T light source that either uses a tungsten, fluorescent, or halogen bulb. The microscopes with the fluorescent bulb system are usually more expensive than the others, and their light quality surpasses that of the halogen or tungsten as it give out lesser heat and brighter light.
LED illuminators and the fluorescent systems cost almost the same price and LED illuminators are stealing the spotlight in microscopy. Even though the two have similar color rendition problems, LED illuminators have more benefits, as LED illuminators can draw in lesser power and they do not emit heat. Also, talking about a battery powered microscope, microscopes with LED illuminators are the best choice, and this is because they consume less power.
The quality of the eyepiece and that of the objective lens will determine the optical quality of the microscope, but this is secondary. The standard for an objective lens of good quality is an achromatic lens.
The main use of achromatic lens is to ensure that the objectives are compatible Deutsch Industry Norm (DIN). DIN objectives are very important because you can change from a DIN compatible microscope to another. So, this means that instead of buying a new microscope, you can simply replace the damaged one.
A wider eyepiece lets you view objects easily. Wide field (WF) or super wide field eyepieces (SWF) are some of the best eyepieces. Also, you should keep in mind that the lens width reduces relative to the magnification power size.
This is a very important part of the microscope. It becomes very important when you are viewing at high magnifications.
You will find it very easy to move the slide in a fine differential if your microscope has a good mechanical stage. This means watching a moving organism across the slide will not be difficult.
The Focusing System
This is the part that is responsible for the movement of the stage. If you want high power use, you need a fine adjustment system that works effectively in addition to the course adjustment knob.
Make sure the knobs of the microscope have no backlashes. There may be the need to turn the fine adjustment knob in the two directions when you are making use of the microscope, so it has to work efficiently without issues.
Abbe Condenser and Iris Diaphragm
If you are going to buy a compound microscope, it is mandatory to check if it has a condenser and iris diaphragm that is good. The best condenser will make sure there is optimum level of adjustments.
How To Use a Microscope
After reading microscope reviews on the internet and determining the best microscope for you, you need to learn how to use your microscope the right way.
Here is a simple guide on how to use a microscope.
Use a Flat Surface
When you’re using your microscope, make sure you use it on a flat surface so that you get an accurate view of your slides. Using it on a flat surface also ensures that you don’t damage your microscope. If the surface you are using your microscope on is uneven, you may get uneven view of your slides.
Make sure that your microscope is clean
Another thing that can cause problems to even the best microscope for kids is if the lens isn’t very clean. Cleaning your microscope lens is not different from cleaning your glasses. All you have to do is to breathe condensation onto the microscope lens and wipe it clean with lens tissue. Cleaning the lens rightly can help you to get a very clear image of your subject.
Reduce Eye Fatigue
Eye fatigue is something you will need to consider before you start to use your microscope. A common health issue that can arise when you use a microscope too much is eye fatigue, which results as a result of using your eyes too much. Eye fatigue can be prevalent in many different ways such as eye strain, red eyes, etc. You can prevent or reduce eye fatigue by reducing the amount of time you spend using your microscope.
How To Clean Microscope Lens
Most microscope specialists say that it is better when you clean your microscope less. However, the time will eventually come when you have to give your microscope lens a good cleaning
Here are some tips on how to clean your microscope lens properly.
The first thing to do is to locate the dirt. Find out if the dirt is on the objective lens or the eyepiece lens. If you look into your microscope and see notice a spot in it and you also see the spot at all powers, this is an indication that the spot is not inside, but on the outside of your eyepiece lens. Turn your microscope eyepiece if you can, if the spot on the eyepiece moves, then you are certain that the dirt is on the eyepiece lens. If the spot doesn’t move, then it is inside and might need to be cleaned by a professional.
Sometimes, you just need to blow off the dusts. Use a camera lens cleaner bulbs or use a squeeze bulb. You can also use the compressed air cans that are used to clean computer keyboards. Avoid using sprays with cleaners. Once you have blown your microscope lens clean gently wipe the lens with an approved lens cloth.
Do not remove your microscope lens unless it is necessary. Also, remember to keep the microscope lens covered as dust is the number one destroyer.
