Among the useful microscopes today is the battery powered microscope. There are different types of battery powered microscopes according to the power source - they are the alternating current, rechargeable battery pack, regular alkaline batteries, and the combination type (AC power and batteries).
The first one is a microscope that uses the alternating current, which runs for a certain period of time and it flows to a single direction and as well as the opposite direction. This type of power source is both used for lighting and power. As you would know, an AC, in its abbreviated form, matches to your standard power output. Using the AC mode, most microscopes are powered with one foot or even two feet value of power cord. In every country, there are standard power voltages. Your particular power voltage will depend on the corresponding number of live circuit connection in your country. So if you start using a microscope utilizing an alternating current, make sure that it matches with your standard power voltage.
The alternating current is often compared to direct current or DC. AC’s voltage can be lowered or raised with the use of a transformer. It is also better in terms of transmission and generation if set in high voltage. Another benefit from its use is the capability to be safely utilized if set in low voltage. Almost all industries nowadays are using alternating current as well as in relation to microscopy. So with this type of microscope, you are able to receive continuous power. Most complicated microscopes need more energy for them to function properly. However, it will still be a risk to depend on this type of microscope as the flow of current is not stable. We sometimes experience power interruption and get empty handed in the middle of a study. It will also be difficult to bring the microscope outdoor as power sources are not as common as staying in your household. In these cases, its use will be limited to indoor areas only such as laboratories, schools, and homes.
The second type is the microscope that has a rechargeable battery pack. As a power source, it is widely used in cameras, mobile phones, music players, and other popular gadgets. It is easy to use as you just have to connect its charger to the power source and there goes your batteries recharging for an hour or two and you can do this for even 500 times. A lot of people find it practical as having a rechargeable battery means a considerable savings, which brings greater power efficiency and cost effectiveness compared to other batteries or sources of power.
If you have this type of battery powered microscope, you can expect a continuous supply of power not to mention the portability of the equipment wherever you might want to go to study your subject. On the contrary, microscopes like this can only function as long as the rechargeable v\batteries hold to its power. If it does not, then function is impaired as well. You have to bother recharging your batteries again before you can even start using your microscope again. It is not certain that you will always have a power source to rely on when you drain your batteries.
Another type is the microscope, which uses regular alkaline batteries. These are batteries, which you can easily buy from the neighborhood store. They are featured indifferent sizes like AAA, AA, B, and C. Sizes purchased will depend on the microscope being used. When using this type of microscope, you can expect a longer shelf life with reference to the alkaline battery. But these batteries have to be used continuously or they will lose their energy once put away for a longer time.
Portability is the main advantage from using a microscope powered by alkaline batteries. And because it is generally available, you can easily purchase new sets if the old ones run out therefore your microscope can be used as you long as you need it without needing to recharge. It will be a great advantage if you do an off-site study such as in the mountains where no power source is available. But still, its power is limited, which means that sophisticated microscopes do not correspond with this power source as illumination will be as intense as the microscopes using AC power source.
Lastly, we have the combination type battery powered microscope. This type is powered by two various sources such as the AC power source and the batteries in an alternate manner. Sound better, right? Yes, it does. It is also the same as saying that you have a back up. If you run out of power from your batteries, you can easily lug in to any AC source and recharge the batteries at the same time. This will enable you to continue your work and save time.
Having this type of microscope is wiser as you are using more ways for more convenience. Depending on which location you choose to study your subject, may it be in a laboratory, you can always use an available power outlet for AC sources or use batteries when stationed outdoors. One disadvantages, however, is the cost you have to bear with this type of microscope. This probably costs high and may not be affordable to everybody.
