A magnifying glass is an instrument that can be used to observe the subtle details of an object. It is a simple visual optical instrument and a converging lens with a focal length smaller than the visual distance of the eye. Many friends must have heard of a 10x magnifying glass.

What is a ten-fold magnifying glass?

The use of 10x magnifying glasses is mainly professional, such as antique collection appraisal, professional clothing and textile graphic inspection, etc. However, there are many magnifying glasses on the market that are actually 2x magnifying glasses, but they are said to be 10x or even 20x, so please be sure to learn more when purchasing. A magnifying glass is defined as a simple visual optical device used to observe the tiny details of an object. It is a converging lens with a focal length much smaller than the eye's clear vision distance. The size of the image of an object on the retina of the human eye is proportional to the angle between the object and the eye. The larger the angle of view, the larger the image, and the more details of the object can be distinguished. Moving the object closer can increase the angle of view, but it is limited by the eye's ability to focus. Use a magnifying glass, bring it close to the eye, and place the object within its focus to form a positive virtual image. The function of a magnifying glass is to enlarge the angle of view.

The role of a magnifying glass

1. Magnify the image of an object: A magnifying glass is an instrument that can be used to observe the subtle details of an object. It is a simple visual optical instrument and a converging lens with a focal length less than the clear vision distance of the eye. The reason why people can see objects is that objects can form an angle on the retina of the human eye that is proportional to the angle between the object and the eye. If the viewing angle becomes larger, the image formed in the eye will also be larger, and every subtle detail of the object can be accurately seen. Moving the object closer to the eye can increase the person's viewing angle, but the focusing ability of the human eye is limited. Using a magnifying glass, put the object in front of the eye and put the object outside the magnifying glass at the same time, you can see an upright and enlarged virtual image, and the magnifying glass can achieve the purpose of enlarging the viewing angle.

2. Focusing to make fire: Under strong light, the focal part of the lens will be particularly bright, and the focal part will zoom or catch fire.

What are the precautions when using a magnifying glass?

Notes on using a magnifying glass:

1. Be careful not to collide with hard objects such as steel to prevent the magnifying glass from breaking.

2. Do not use strong light to face your skin to avoid burns or to face flammable items to cause fire.

3. Do not place it in humid air.

A magnifying glass is a simple visual optical device used to observe the details of an object. It is a converging lens with a focal length much smaller than the clear vision distance of the eye. The size of the image of an object on the retina of the human eye is proportional to the angle (angle of view) between the object and the eye. The larger the angle of view, the larger the image, and the more details of the object can be distinguished. Moving the object closer can increase the angle of view, but it is limited by the focusing ability of the eye. Use a magnifying glass, bring it close to the eye, and place the object within its focus to form a positive virtual image. The function of a magnifying glass is to enlarge the angle of view.
