How Does a Magnifying Glass Work? [2023 Updated Guide]



How does a Magnifying Glass Work?

Assuming you would like to know discussion of How does a Magnifying Glass Work. Well. I have great explaination for you. So, keeep read the whole article with carefully.

Magnifying glasses are the most useful tool to observe tiny objects in a bigger view. All magnifying glasses follow the same principle to zoom the object. From scientists to students, everyone uses magnifying glass for a different purpose. If you are a hunter, you might be familiar with spotting scopes and binoculars.

All of these are a kind of magnifying glasses from the higher level. Rather than that, magnifying glasses are also an essential tool for travelers and hunters to observe tiny little details of any object. Let’s explore  how a magnifying glass works in real life.

How Does a Magnifying Glass Work?

Before going into details of the working procedure of a magnifying glass, it is essential to talk a little bit about the role of light in watching objects through our eyes. Have you ever thought about why we cannot see anything during a blackout? Well, there is no light source presence; that’s why. So it is clear that the light source is essential for watching any object. But how?

Well, at first, the light falls on the object. The light itself is a wave. So, when the light falls on any object, it absorbs some waves, and the rest of the light is reflected in the world. This reflected wavelength lies between the visible ray’s ranges. When someone looks at an object, the reflected light comes straight to our eyes, and thus we can see the object.

The same principle is applied when we use a magnifying glass to observe a tiny little object. So, now the question arises, “Then what’s the difference?” The straightforward answer is that we don’t watch objects on a magnified scale with our bare eyes. It is the exact measure of objects while watching with bare eyes. On the other hand, a magnifying glass does both; it helps us watch the image on a larger scale.

Structure of a Magnifying Glass

The basic structure of a magnifying glass is two convex lenses joined together. A convex lens is a kind of lens bulged from the outer side. This could be made of either glass or plastic. The glass provides a clearer image. It is the basic structure of a microscope as well.

How is a Magnifying Glass used as a Binocular?

A magnifying glass is the simplest version of every magnification device. For Hunters, it is necessary to use binoculars to observe animals from far.

It is also important to notice that binoculars are also used for tracking, so a clear view is also a must for hunters. All binoculars follow the same principle as mentioned above. They contain lenses and prisms. Two convex lenses are used to magnify the animal or objects for the lens.

One is called an objective lens, and the other one is called an eyepiece lens. The alignment of these lenses is not straight. For this reason, we use prisms inside the binoculars. It helps to align the ray, which comes from the objective lens. After the alignment, the ray is fallen to the eyepiece lens.

This convex lens magnifies the object, but there are other features as well. Binoculars can magnify any object into various magnification scales. For example, 2X, 4X, 8X, 16X etc. Also, binoculars come with the focus feature, which helps to focus on an object to get a clear view.

This time, the reflected light from the object does not come to the eye directly. The light ray passes the convex lens at first then it reaches our eyes. When the light falls on the lens, it converges the light ray and creates a magnified image on the other side of the lens. Though the image is virtual, it tricks our minds believe that it is a real one.

Also, the formulated virtual image is upside down. But the human eye has this amazing feature that it automatically rotates the upside-down image and gets the right-oriented view.


How is a Magnifying Glass used in Rifle Scopes?

A magnifying glass is also used in rifle scopes to locate an animal. It is a necessary tool for hunters as it is mounted on the rifle. The riflescope contains objective assembly and ocular assembly as well. Rather than that, the riflescope also has an erector assembly. This erector assembly makes the flipped image into the right orientation.

This erector system also contains convex lenses that are involved in magnifying the view. They can be found in different shapes and sizes. Also, the magnification range can be from 2X-30X or even more.

How is a Magnifying Glass used in Spotting Scopes?

Spotting scopes are very popular among hunters and adventurous people. Spotting scopes are widely used when binoculars can’t meet the user’s satisfaction. Because spotting scopes offer a wide range of magnification that sometimes can’t be achieved from binoculars, spotting scopes are the first choice for hunters and observers to observe from long distances.

It also contains convex lenses, which is used to magnify objects from long distance. The basic working principle is the same as binoculars. But they contain bigger lenses with some new features that are missing in the binoculars.

How is a Magnifying Glass used in a Rangefinder?

If you are into golf, then you might be familiar with rangefinders. They are used to measure the accurate distance from a place using a laser. The laser is sent out and then reflected back to accurately measure distances. The optics used in the Rangefinder is a convex lens as well.

The Rangefinder can achieve a magnification of 5X-10X from the Rangefinder. These rangefinders are also very useful for hunting. It can provide an almost accurate distance of an animal from the hunter, which makes it easier to aim.

Last Guide

Convex mirrors are fundamental for the magnification of any object. Every modern equipment still uses this convex lens for different magnification purposes. From heavy scientific research to outdoor hunting, magnifying glasses are everywhere. I’ve tried to tell you how the magnifying glassworks in this article. I hope this will help you understand How Does a Magnifying Glass Work?. Happy Hunting.
