Binoculars 12x25 What Does It Mean ?

The numbers "12x25" on binoculars refer to the magnification power and objective lens diameter, respectively. The "12x" indicates that the binoculars provide 12 times magnification, meaning that the viewed object will appear 12 times closer than it would to the naked eye. The "25" represents the diameter of the objective lenses in millimeters. In this case, the objective lenses have a diameter of 25mm. The larger the objective lens diameter, the more light can enter the binoculars, resulting in brighter and clearer images.

1、 Magnification: 12x

Binoculars 12x25 refers to a specific type of binoculars with a magnification power of 12x and an objective lens diameter of 25mm. The first number, 12x, indicates the magnification power, which means that the object being observed will appear 12 times closer than it would to the naked eye. This level of magnification is considered quite powerful and is suitable for a variety of activities such as birdwatching, wildlife observation, or even stargazing.

The second number, 25, represents the diameter of the objective lens in millimeters. The objective lens is the larger lens at the front of the binoculars that gathers light and helps create a brighter and clearer image. A larger objective lens allows more light to enter the binoculars, resulting in a brighter image, especially in low-light conditions.

Binoculars with a 12x magnification and a 25mm objective lens diameter are generally compact and lightweight, making them ideal for outdoor activities where portability is important. They are often referred to as "compact binoculars" and are popular among travelers, hikers, and sports enthusiasts.

It is important to note that while a higher magnification can bring distant objects closer, it also reduces the field of view and can make the image shakier. Therefore, it is recommended to use a tripod or stabilize the binoculars against a solid surface when using higher magnification binoculars.

In conclusion, binoculars 12x25 refers to a compact and portable binoculars with a magnification power of 12x and an objective lens diameter of 25mm. They offer a powerful magnification and are suitable for various outdoor activities.

2、 Objective Lens Diameter: 25mm

Binoculars 12x25 refers to a specific type of binoculars with a magnification power of 12x and an objective lens diameter of 25mm. The magnification power of 12x means that the binoculars can make objects appear 12 times closer than they actually are, which is quite powerful for a compact pair of binoculars. The objective lens diameter of 25mm indicates the size of the front lenses that gather light and determine the brightness of the image.

The 12x magnification is ideal for various outdoor activities such as birdwatching, wildlife observation, or even stargazing. It allows users to observe distant objects with great detail and clarity. However, it's important to note that higher magnification can also result in a narrower field of view and a shakier image if not used with a tripod or steady support.

The objective lens diameter of 25mm indicates that these binoculars are compact and lightweight, making them easy to carry around. However, a smaller objective lens diameter also means that less light is gathered, resulting in a slightly dimmer image compared to binoculars with larger objective lenses. This can be a trade-off between portability and image brightness.

It's worth mentioning that advancements in lens technology have allowed manufacturers to improve the image quality of binoculars with smaller objective lenses. Coatings and other optical enhancements can compensate for the reduced light gathering ability, resulting in brighter and sharper images.

In conclusion, binoculars 12x25 refers to a compact pair of binoculars with a 12x magnification and a 25mm objective lens diameter. These binoculars are suitable for various outdoor activities and offer a balance between portability and image quality.

3、 Binoculars: Optical instrument for viewing distant objects with both eyes.

Binoculars: Optical instrument for viewing distant objects with both eyes. Binoculars are a popular tool used by outdoor enthusiasts, birdwatchers, hunters, and even astronomers to observe objects that are far away. They consist of two telescopes mounted side by side, allowing the viewer to see a magnified and stereoscopic image.

The numbers "12x25" in the description refer to the magnification and objective lens diameter of the binoculars. The first number, 12x, indicates that the binoculars provide a magnification of 12 times. This means that the object being observed will appear 12 times closer than it would to the naked eye. The second number, 25, represents the diameter of the objective lens in millimeters. The larger the objective lens, the more light it can gather, resulting in a brighter image.

Binoculars with a 12x magnification and 25mm objective lens diameter are considered compact and lightweight, making them suitable for activities such as hiking or traveling. However, it's important to note that higher magnification can also lead to a narrower field of view and a shakier image if not used with a tripod or steady hand.

In recent years, advancements in technology have led to the development of binoculars with higher magnification and larger objective lenses. These improvements have resulted in clearer and more detailed images, making it easier for users to observe distant objects with precision.

Overall, binoculars with a 12x25 specification provide a portable and versatile option for those who want to enjoy the benefits of magnified vision while on the go.

4、 12x Magnification: Objects appear 12 times closer than with naked eye.

Binoculars 12x25 refers to a specific type of binoculars with a magnification power of 12x and an objective lens diameter of 25mm. The numbers 12x25 indicate two important features of these binoculars.

The first number, 12x, represents the magnification power. This means that when using these binoculars, objects will appear 12 times closer than they would with the naked eye. For example, if you are observing a bird that is 100 meters away, it will appear as if it is only 8.3 meters away through the binoculars. This magnification allows for detailed and close-up views of distant objects, making it ideal for activities such as birdwatching, wildlife observation, or even stargazing.

The second number, 25, refers to the diameter of the objective lens in millimeters. The objective lens is the larger lens at the front of the binoculars that gathers light and forms the image. A larger objective lens diameter allows more light to enter the binoculars, resulting in brighter and clearer images. However, a larger objective lens also means a heavier and bulkier pair of binoculars. The 25mm objective lens in the 12x25 binoculars strikes a balance between portability and image quality.

It is important to note that the magnification power and objective lens diameter are not the only factors to consider when choosing binoculars. Other factors such as the quality of the optics, field of view, and overall build quality also play a significant role in determining the performance and suitability of binoculars for specific activities.

In recent years, advancements in technology have led to the development of binoculars with higher magnification powers and larger objective lens diameters. These advancements have allowed for even more detailed and immersive viewing experiences. However, it is essential to find the right balance between magnification, lens diameter, and overall quality to ensure a comfortable and enjoyable viewing experience.
