How to Read Scope Numbers: A Guide for Beginners

How to Read Scope Numbers

When you’re shopping for a new scope, you’ll likely come across a number of different models, each with its own set of specifications. One of the most important things to consider is the scope’s magnification power, which is typically expressed as a two-number combination, such as “7×32.” The first number, in this case 7, represents the magnification, and the second number, 32, represents the objective lens diameter.

In this article, we’ll take a closer look at scope numbers and explain what they mean. We’ll also discuss how to choose the right scope for your needs.

What do scope numbers mean?

The first number in a scope number represents the magnification power. This is the number of times the image will be magnified when you look through the scope. For example, a scope with a magnification of 7x will magnify objects seven times their actual size.

The second number in a scope number represents the objective lens diameter. This is the diameter of the lens at the front of the scope, and it’s measured in millimeters. The objective lens diameter is important because it determines how much light the scope can gather. A larger objective lens will gather more light, which can result in a brighter image.

How to choose the right scope for your needs

When choosing a scope, you need to consider a few factors, including your intended use, your budget, and your personal preferences.

• Intended use: The most important factor to consider when choosing a scope is your intended use. If you’re planning on using the scope for hunting, you’ll need a scope with a high magnification power. If you’re planning on using the scope for bird watching, you’ll need a scope with a large objective lens.
• Budget: Scopes can range in price from a few hundred dollars to several thousand dollars. The amount of money you’re willing to spend on a scope will depend on your budget.
• Personal preferences: Some people prefer scopes with illuminated reticles, while others prefer scopes with simple reticles. Some people prefer scopes with long eye relief, while others prefer scopes with short eye relief.

Scope numbers can be a bit confusing at first, but they’re actually quite simple to understand. By understanding what scope numbers mean, you can choose the right scope for your needs.

What is a scope number?

A scope number is a combination of numbers and letters that are used to identify a rifle scope. The scope number typically includes the following information:

• Objective lens magnification: This is the first number in the scope number and indicates the magnification power of the scope. For example, a scope with a 4x magnification would have a scope number of 4-16×44.
• Eyepiece magnification: This is the second number in the scope number and indicates the magnification power of the eyepiece. For example, a scope with a 4x magnification and a 16x eyepiece would have a scope number of 4-16×44.
• Objective lens diameter: This is the third number in the scope number and indicates the diameter of the objective lens in millimeters. For example, a scope with a 4x magnification and a 16x eyepiece and a 44mm objective lens would have a scope number of 4-16×44.
• Other features: The scope number may also include other features, such as the type of reticle, the number of illuminated reticles, and the length of the scope.

How to read the first part of a scope number (objective lens magnification)

The first part of a scope number indicates the magnification power of the objective lens. The magnification power is expressed as a ratio, with the first number representing the low-power magnification and the second number representing the high-power magnification. For example, a scope with a 4-16x magnification would have a low-power magnification of 4x and a high-power magnification of 16x.

The magnification power of a scope is important because it determines how much you can magnify an object. A higher magnification power will allow you to see more detail, but it will also make the object appear smaller. A lower magnification power will allow you to see a larger area, but it will not provide as much detail.

When choosing a scope, you need to consider the magnification power that you need for the type of shooting that you will be doing. For example, if you will be hunting deer in the woods, you will need a scope with a low-power magnification so that you can see the deer over long distances. If you will be shooting targets at the range, you will need a scope with a high-power magnification so that you can see the target clearly.

Here are some tips for choosing the right magnification power for your scope:

• If you will be shooting at targets that are close to you, you will need a scope with a low-power magnification.
• If you will be shooting at targets that are far away from you, you will need a scope with a high-power magnification.
• If you will be hunting in thick brush or woods, you will need a scope with a wide field of view.
• If you will be shooting at moving targets, you will need a scope with a fast focus.

By considering the factors above, you can choose a scope with the magnification power that is best for your needs.

How to read the second part of a scope number (eyepiece magnification)

The second part of a telescope’s model number is the eyepiece magnification. This number tells you how much the telescope will magnify objects. For example, a telescope with a model number of “10×50” has a magnification of 10x.

To calculate the magnification of a telescope, you simply multiply the focal length of the objective lens by the magnification of the eyepiece. For example, a telescope with a 100mm objective lens and a 20x eyepiece would have a magnification of 100mm x 20x = 2000x.

The magnification of a telescope is important because it determines how large objects will appear in the field of view. A higher magnification will make objects appear larger, but it will also reduce the field of view.

When choosing a telescope, you need to decide what magnification you need for the type of observing you will be doing. For general observing, a magnification of 20x to 40x is a good starting point. For bird watching or viewing planets, a magnification of 40x to 100x is ideal. For deep-sky observing, a magnification of 100x or more is necessary.

It is important to note that the magnification of a telescope is only one factor to consider when choosing a telescope. Other factors, such as the aperture of the telescope and the quality of the optics, are also important.

How to read the third part of a scope number (exit pupil diameter)

The third part of a telescope’s model number is the exit pupil diameter. This number tells you how much light the telescope will gather. The exit pupil diameter is calculated by dividing the focal length of the objective lens by the magnification of the eyepiece. For example, a telescope with a 100mm objective lens and a 20x eyepiece would have an exit pupil diameter of 100mm / 20x = 5mm.

The exit pupil diameter is important because it determines how much light will reach your eyes. A larger exit pupil will allow more light to reach your eyes, which will make objects appear brighter.

When choosing a telescope, you need to consider the size of your exit pupil. If you have a small pupil, you will need a telescope with a large exit pupil in order to see objects clearly. If you have a large pupil, you can get away with a telescope with a smaller exit pupil.

It is important to note that the exit pupil diameter is not the same as the aperture of the telescope. The aperture of the telescope is the diameter of the objective lens. The exit pupil diameter is the diameter of the light beam that is coming out of the eyepiece.

The first two parts of a telescope’s model number tell you the focal length of the objective lens and the magnification of the eyepiece. The third part of the model number tells you the exit pupil diameter.

The focal length of the objective lens determines how much light the telescope will gather. The magnification of the eyepiece determines how large objects will appear in the field of view. The exit pupil diameter determines how much light will reach your eyes.

When choosing a telescope, you need to consider all three of these factors in order to make the best decision for your needs.
