What are microscopesmade of

Although they sound very similar, the main difference is anti-glare protects from external light sources; diffusing light which bounces off surfaces (such as roads, water or snow) and causes that blinding glare. Whereas anti-reflective lenses go one step further by diffusing both internal and external light sources and removing reflections within your lenses.

An electron microscope is defined as the type of microscope in which the source of illumination is the beam of accelerated electrons. It is a special type of microscope with a high resolution of images as the images can be magnified in nanometers.

Microscope parts and functions

A compound microscope is defined as the type of microscope that has more than one lens. It has a combination of lenses and two optical parts known as an objective lens and an eyepiece or ocular lens. The magnifying power of the compound microscope is given as:

An anti-reflective coating can be applied to both prescription and non-prescription lenses, so no matter your lifestyle, everyone can benefit from anti-reflective glasses! With laptops, phones and digital devices becoming more constant in our day-to-day lives, anti-reflective coatings help protect your eyes from excess LED or artificial light, these are more commonly known as blue light glasses. If you drive a lot, especially at night, anti-reflective can also reduce the distraction of blinding reflections, allowing you to have a clear sight of the road or potential hazards ahead.

The metal used in an electron microscope is tungsten. A high voltage current is applied which results in the excitation of the electrons in the form of a continuous stream that is used as a beam of light. The lenses used in the electron microscope are magnetic coils. These magnetic coils are capable of focusing the electron beam on the sample such that the sample gets illuminated. As the flow of current increases, the strength of the magnetic lens increases. The electron beam flow is designed such that it cannot pass through the glass lens.

The working principle of a simple microscope is that when a sample is placed within the focus of the microscope, a virtual, erect and magnified image is obtained at the least distance of distinct vision from the eye that is held at the lens.

With more light transmitting into your eyes (99% in fact), you can fully see what’s ahead of you—providing sharper images, crisper contrasts, and more confidence in your sight.

What are microscopesused for

There are different types of microscopes and each of these has different purposes of use. Some are suitable for biological applications, while others are used in educational institutions. There are also microscope types that find application in metallurgy and studying three-dimensional samples.

Have you ever found yourself squinting because light (real or artificial) is reflecting into your line of sight? Anti-reflective lenses eliminate these frustrating reflections. Also known as anti-glare or AR, this particular coating removes scattered light which reflects on the front and back of your glasses lenses. Permitting up to 99% of light into your eye ultimately enhances your vision, creates sharper visuals and allows others to see you more clearly too.

Compound microscope

Anti-reflective coating is made up of a thin chemical layer which is applied to both the front and back of your lenses. It is a very effective coating which eliminates the unnecessary light which causes glare and reflective distractions. Instead, it emits more light into your eye, helping improve vision. On average, anti-reflective lenses can last up to 2 years, if correctly cared for.

The working principle of the compound microscope is that the combination of lenses enhances the magnification of the sample. The sample is first viewed as a primary image in the tube and viewed again in the eyepiece.

The scanning probe microscope has a probe tip that is mounted on the end of a cantilever. The tip is so sharp that it can move precisely and accurately across the surface of the sample scanning every atom. The tip is placed close to the surface of the sample, such that the cantilever experiences a deflection due to forces. This deflection distance is measured by the laser. The final image after scanning is obtained on the computer.

The basic difference between low-powered and high-powered microscopes is that a high power microscope is used for resolving smaller features as the objective lenses have great magnification. However, the depth of focus is greatest for low powered objectives. As the power is switched to higher, the depth of focus reduces.

The field of view in a microscope is defined as the diameter of the illuminated circle which is seen through the eyepiece. With an increase in the magnification, there is a decrease in the field of view.

A stereo microscope is defined as a type of microscope that provides a three-dimensional view of a specimen. It is also known as a dissecting microscope. In a stereo microscope, there are separate objective lenses and eyepiece such that there are two separate optical paths for each eye.

Types of microscope

A stereo microscope works on the reflected light from the sample. The magnification of the microscope takes place at low power and hence, it is suitable for magnifying opaque objects. It is suitable for thick and solid samples because it uses light reflected from the sample. The magnification of the stereo microscope is between 20x and 50x.

In this article, there are 5 such microscope types that are discussed along with their diagram, working principle and applications. These five types of microscopes are:

Anti-reflective lenses become invisible to the camera, so you can enjoy no more reflections in your lenses from flashes or selfies, creating better-quality photos.

The depth of focus in a microscope is defined as the distance between the objective lens and the sample plane. The depth of focus varies from person to person and is also dependent on the quality of focus.

The depth of field in a microscope is defined as the distance from the nearest object plane in focus to the farthest plane in the same focus. In microscopes, the depth of field is very short and is measured in units of microns.

By eliminating the reflection of streetlights, headlights or even your dashboard, you are increasing your vision clarity, helping you stay more alert and reactive on the road.

Due to the delicacy of this coating, you should only use recommended cleaning products on your anti-reflective lenses. Always wet your lenses first before cleaning them with a cloth; they can be easily scratched which is more noticeable on AR lenses.

People working in offices or with digital screens are often exposed to more artificial light which bounces off their lenses. Anti-reflection can reduce this, supporting your eye health.

The scanning probe microscope is defined as the type of microscope that finds applications in industries where the examination of the specimen is done at the nanoscale levels. The study of a specimen’s properties, its reaction time and its behaviour when stimulated can be done with the help of a scanning probe microscope.

A simple microscope is defined as the type of microscope that uses a single lens for the magnification of the sample. A simple microscope is a convex lens with a small focal length. The magnifying power of the simple microscope is given as

As we said, anti-reflective glasses can be worn by anyone and applied to any style of glasses, including sunglasses. Meaning they can be worn all year round, within any setting.

Excess light naturally causes our eyes to squint in order to protect our eyes and focus on what’s in front of us. Less squinting will reduce eye strain, tiredness and headaches too.
