Are you looking for a new hobby which can provide you with tons of learning? Well certainly, a dissecting microscope can get you started. Almost everybody has experienced looking into microscopes and surprisingly people gasp for words to describe what they have just witnessed at that very moment. It can be very fascinating to see tiny things that are quite invisible to our naked eye. The instrument allows you to magnify the view of your subject, may it be sands from the beach, stamps, a petal of a flower, coins, dusts, electronic circuits, and even dreadful viruses. It is also often used to identify insects, botanical study, field trips, and in repairing watches.
So it clearly sounds fun, right? But does it cross your mind that microscopes of this kind are just big boys’ toy? Definitely not; its usefulness may be fun but it is made of strong metal mechanics and its objective is coated with achromatic glass. It can magnify 20x with the benefit of seeing more from the eye. It is easier to use because samples would not have to be prepared. You can actually have any object around the house or take an insect or plants from your garden. You can study them steadfastly. Because it does not have image inversion, you an easily perform manipulation of the subject. It is very useful for low power studies.
On the contrary, you may also require prepared slides in some cases especially when you want to study particular insects that you will have to dissect. These dissected insects have to be prepared in slides. The underlying reason for this is the need for an extremely flat specimen to easily see the details of it under your dissecting microscope. As this type of microscope has sturdy magnification, you will achieve a shallow depth of field, which will enable the specimen to be more focused. Some specimens have to be transparent for the reason that you are working with an incident light. Chemicals are used to make the inset’s external skeleton soft and transparent. Consequently, you can start observing the insect’s anatomical features.
Dissecting microscopes can cost some bucks. But it is more preferred than overkill high end microscopes. If you are a novice, you would want this to become your first microscope as it is moderately priced and certainly serves its purpose. The most important consideration of all aside from its construction should be the optics. Obviously, when defining a good image, it would not be fair fro someone to spend 24 hours taking effort in adjusting his scope to achieve the view required. If that is the case, it would not be a fun hobby anymore but a painstaking useless task.
Added to all of the above, dissecting microscope is very handy. You can use it anytime you want. The subject is usually placed in a Petri dish. It is a shallow dish made of glass which is measuring approximately four inches transversely. If your specimen is an animal, say an alga, from an aquarium which moves around in the water contained in a Petri dish, you can easily glance on it. It also has lights located above and below the subject. This light source can easily be adjusted to your desired brightness. With this, your subject can be properly illuminated.
Most dissecting microscopes have dual objective lenses. These lenses can produce three dimensional stages and comes in various power levels such ranging form 10x up to 80x. Its binocular and trinocular versions are widely available in the market. The binocular dissecting microscope has to eyepieces while the trinocular dissecting microscope enables the addition of photography port if you intend to capture images. A digital camera can be attached to the instrument via USB port and connected directly to computers. This will provide a larger view of the subject looking through your computer monitor. This can also come in objectives with fixed magnification or zoom magnification for a clearer viewing and image control. However, zoom optics are much more expensive. The dissecting microscope with fixed magnification is a better deal as it is much lower in terms of price. It is still good to use in educational hobbies.
Another example for a hobbyist to do with a dissecting microscope is to study coins. Coin collectors typically used this type of microscope as it allows detailed viewing of errors, overstrikes, double dies, mint marks, and condition of the metal coin surface. This microscope is useful too in detecting counterfeits coins. Out of the countless ways to make use this microscope, you will be surprised on how important it is to own one.
