Various types of testing equipments are used for conducting various experiments and gathering data by professionals. In the market (physical and online), you will mostly come across microscope as a common testing instrument. Generally, there are four types of microscopes namely compound microscope, stereo microscope, digital microscope and handheld microscopes.

A microscope is testing equipment used to see objects that are not possible to see from naked eye. In late 16th century, the first microscope uses light to image the sample. It was called the optical microscope. Later, in the early 1900s, microscopes start using electrons rather than light to generate the image. It was named the transmission electron microscope. It allows a much higher resolution. One must remember that the microscope should always be picked carefully by grabbing it in your arm and placing your other hand on the bottom of the base. Never touch the lenses with fingers to avoid smudges. Use only lens paper to clean the glass.

Optical microscopes are commonly used microscopes. It uses ...
... visible light, which refracted with optical lenses to create an image. Optical microscopes can be further categorized - Compound microscopes are composed of two lens systems with the maximum magnification of about 1000 X, whereas stereo microscopes magnify up to about maximum 100 X and supply a 3-D view.

X-ray microscope is a device, which uses a beam of x-rays to create an image. The image resolution is higher than in optical microscopes. The maximum useful magnification is high. Scanning acoustic microscope depends on sound waves to generate an image. They are used to identify small cracks or tensions in materials. Devices that use a beam of Helium ions to generate an image is commonly known scanning Helium Ion microscope. It is the latest technology used in microscopy. It provides a high resolution images.

As you have multiple options as far as microscopes are concerned. Selecting the best is not an easy task. First of all, you must understand your requirement before buying any microscope. Microscope is testing equipment used in academic and industrial settings and research and development. The Internet has also sourced as an easy access avenue to find different types of microscopes – whether used or new. No doubt, online platform helps manufacturers, suppliers, wholesalers and dealers to a large extent these days. Establishing businesses online helps buyers to search for the prominent manufacturing companies based on different product categories. It let buyers to negotiate with sellers or the manufacturers as well.
