From a simple hobby to intensive science projects, microscopes are wonderful tools that serve your needs with ease and precision. When you get a good microscope, you do not even need to buy another one to replace it. Read more about microscope in Malaysia here below to find out.

How to Buy A Microscope

Whether you buy microscope for your science project or hobby, it is useful for viewing objects that are too small for the naked eye. Despite this, a lot of people do not know how to get the ideal microscopes. Needless to say, they get the wrong microscopes that do not perform well. Thankfully, here is how you can a suitable microscope that matches your needs.

Design of Microscope

Naturally, you should get a microscope that is well-built and can last for years of usage. In other words, this high-quality microscope is built to highest standards and utilize the best materials in its construction. The best microscope you can find is the one that is made of metallic alloys that minimize vibration and experience minimal fluctuation with temperature variations. When a scope is made of plastic, you should avoid it at all costs. At the same time, you should be careful of toy scopes that are painted or chromed to look metal.

Although it is difficult to discern online or in a catalog, you can always compare actual weights (not shipping weight) and measurements. This allows you to have a better understanding of its size and sturdiness. A complete microscope should consist of optical glass lenses, metal focus gear with metal screws to metal frames, reagent resistant finish (paint job), and ball bearings in vital moving parts.

Microscope Optics

When it comes to lenses, "DIN" (Deutsche Industrie Norm) is an international standard for microscope objective lenses. Sometimes, you may see "JIS", which is a Japanese standard. A scope that adheres to DIN standards can get its lenses replaced with another one from nearly any microscope companies in the world.

Achromatic lenses are color corrected. If the lens is not color corrected, there are things that you simply will not see with your microscope. Achromatic lenses will serve you well for most student, school, and hobbyist applications. The achromatic standard specifies that the center 60% of the field of view appears as flat and focused without aberration. With achromatic lenses, any chromatic (color) and spherical (focus/flatness of field) aberrations will be in the outer 40% of the field of view.

Light

The tungsten light (also known as "incandescent light") is the least expensive type of microscope bulb available today. While it is a steady source of light, its disadvantage is that it produces yellowish light that affect color accuracy of the specimen being viewed. When you need to replace the bulb, it is hard to find the exact replacement because there is no standard bulb. Besides, it generates heat that can dry out specimens.

The fluorescent light in microscope can be more expensive but it is less expensive to operate. Since it produces white light, objects look more like they really do in nature. It also produces less heat as well. Thanks to cool factor and better visibility, it is little wonder that fluorescent light is a popular choice these days.

Focus

The focus system on a microscope brings the subject that you want to observe into the focal plane of the objective lenses. The microscope's focus system will have one or two focus knobs. Each microscope has at very least a coarse focus. If a scope has just one focus knob, it is a coarse focus. A fine focus adjustment was at one time a feature just for high-end instruments. Providing a better magnifying effect, a fine focus adjustment also makes a microscope easier for children to use.
