Importanceof microscope

A dissecting microscope is used to view three-dimensional objects and larger specimens, with a maximum magnification of 100x. This type of microscope might be used to study external features on an object or to examine structures not easily mounted onto flat slides.

Both microscopes have similar features. Each microscope has an eyepiece as well as a light source. Light microscopes usually have eyepieces that are magnified 10x plus multiple objective lenses that are magnified between 4x and 100x (SF Fig. 2.2 A). The total magnification is calculated by multiplying the eyepiece magnification (10x) by the objective lens magnification (e.g., 40x), for a total magnification would be 400x. On a light microscope, a sample is placed on a glass slide and light is passed through the sample from underneath the stage. This type of microscope shows great detail of small, thin objects. To view thicker objects, the tissue sample must be thinly sliced and prepared on a glass slide in two-dimensions. With a dissecting microscope whole objects can be viewed in three dimensions. Samples do not need to be sliced, and larger, live animals can be observed. Light can be passed through from underneath the sample, but also from the top or side using an external light source. However, the magnification power of the dissecting microscope is less powerful than that of a light microscope.

Purpose of microscopein microbiology

Microscopes are useful tools for visualizing small structures in great detail. There are two common types of microscopes used in laboratories when studying algae: the compound light microscope (commonly known as a light microscope) and the stereo microscope (commonly known as a dissecting microscope).

Description:        Anti Green Laser Protection  Safety Glasses [532nm] is an eye protection glass against green laser with 523nm wavelength. As you know, the laser is a light, but a coherent light in a narrow wavelength range, to achieve more and more energy than usual light. Depends on the laser diode types, this energy varies from several milliwatts to hundreds of watts, that each level of the energy needs to perform safety precautions.  This laser set can emit laser with a 45mW low power, but this low power is not completely safe and can damage to the sensitive and soft tissues especially the eyes of a human, animal and so on. Thus seriously recommended avoiding shotting laser light towards any eyes and use a proper eye protection glass against laser lights while working with the laser applications.This protective glasses are designed and specialized just for green laser with 523nm wavelength, means that it can't protect against other lasers such as Red laser, Blue laser, and so on. This glass is made of Polycarbonate strengthen-eyeglasses material to achieve shock-resistance and starch-proof that provides full protection against green laser, UV light, and high light.

A light microscope is used to visualize objects flattened onto glass slides in great detail. It typically has a magnification power of up to 1000x. A light microscope might be used when examining individual cells within living tissue.
