What Does 3 9×32 Scope Mean? – Full Overview, FAQs & More

What do numbers mean on a scope?

To be more specific, what do 3 9×32 scopes mean?

Let’s find out.

What Do 3 9×32 on a Rifle Scope Mean?

A 3-9×40 Scope is a great choice for hunting. Three times (3x) magnification is perfect for close-up work. Nine times (9x) magnification is more than enough to take accurate shots at longer distances. 40mm is the objective lens diameter.

What Do Scope Numbers Mean?

A mid-range spotting scope offers a minimum magnification of 20x and a maximum magnification of 60x. Objective lens diameter of 80mm.

A crossbow scope is a device used to magnify an image. A fixed scope does not zoom in or out. The first number before the x denotes magnification power or power range, and the second number after the x denotes the size of the objective lenses in millimeters.

Magnification is a measure of how much closer something appears when viewed through a microscope. A higher number indicates more magnification. For instance, if you were looking at a bug under a 10X microscope, it would appear about ten times smaller than normal. With a 50X microscope, it would be half as big again (5X). And with 100X, it would be 1/10th as big again (1X)

Objective Lens Sizes

Binoculars are designed for seeing distant objects. Spotting scopes are designed for seeing close-up objects. A rifle scope is designed for shooting targets at long distances. Crossbows use a bow and arrow to shoot projectiles at targets.

A scope needs a bigger objective lens than binoculars because you are zoomed in on a specific target. Spotting scopes need to let in more light to make it easier to see at their higher magnifications.

Spotter Scope 

A spotter scope is used by snipers to get a better view of what’s going on around them. Spotting scopes give a wider field of view, but they’re also more expensive.

Eye Relief inches or mm – range

Eye relief tells you how close you need to be to the surface to see the entire field of view. Lower power scopes will generally have a larger distance than higher power scopes.

A typical eye relief distance for a rifle or crossbow scope is 3-4 inches. This means that if you’re shooting at a target 10 feet away, you should be able to see the entire target without having to move your head more than 4 inches.

A spotting scope lists eye relief as the distance between your eyes and the front end of the lens. Eye relief is measured in millimeters. For example, a 17mm eyepiece gives you 17mm of eye relief. You need to know the maximum eye relief before buying a spotting scope. Otherwise, you might be disappointed when you try out the scope and realize you can’t use it because your glasses push your eye too far back.

Exit Pupil mm

Exit pupils vary greatly depending on the type of weapon used. For example, an assault rifle or sniper rifle will have a much larger exit pupil than a handgun. This means that the shooter must be very close to the target if using a long-range weapon. However, a handgun may be fired from further away because the bullet travels faster than sound. Therefore, the bullet hits the target before the sound reaches the ear.

Tube Diameter mm

A larger tube means that you can adjust your scope up higher from the rifle. This allows you to see further away.

Length inches or mm

The longest length of the scope from the tip to the tip is 8 inches.

Weight kg or oz

A scope adds weight to a rifle. You should weigh the scope before buying it.

Magnification Explained

Scope magnification is measured by how much an object appears larger when viewed through a scope. Magnification increases as you increase the power setting. At 4 power, the scope makes objects appear four times larger than they do without a scope. At 24 power, the scope makes things appear twenty-four times larger.

This magnification against the naked eye requires a person with a vision of 20/20. Scopes from every country or region use the power magnification as opposed to the naked eye approach, and this magnification approach applies universally in the scope world.

Scope Types

Riflescopes are loosely grouped into two different categories: fixed power scopes and adjustable powered scopes.

Fixed Powered Scopes

A fixed power scope is a type of scope that has a fixed magnification setting. These scopes were very popular during the 1960s and 1970s because they were inexpensive and easy to use. They are still used today by hunters who want a scope that doesn’t require much adjustment.

Fixed-power scopes are simple and easy to use. They don’t offer much adjustment or features. Most people used them for hunting deer and other games.

Adjustable power scopes were introduced when fixed power scopes became too expensive. This caused them to become less popular.

Variable Power Scopes

Variable power scopes have a magnification range that can vary from one power to another by rotating an adjustment ring. The early models had a very low range of magnifications, while modern models have a range of magnifications that average eight magnifications but can go higher than twenty-five magnifications.

Variable powered scopes have become the industry standard because they’re easy to use and affordable. There are only a few fixed-powered scopes that are still being produced, but they’re more expensive than variable scopes. Variable scopes come in three different configurations: 3x to 9x, 6x to 18x, and 8x to 40x.

How to Read Scope Numbers?

Fixed power scopes are used by astronomers to view objects far away. A telescope uses lenses to magnify an image. Magnification is how much bigger something looks when viewed through a lens. For example, if you were looking at Jupiter through a 10x lens, Jupiter would be about 100 times larger than it actually is.

A scope is a tool used by hunters to help them aim accurately. Fixed power scopes are used when the hunter knows exactly what he or she wants to shoot. Variable power scopes are used if the hunter doesn’t know exactly what he or she needs to shoot. Scopes come in many sizes and shapes. Some scopes are designed to be mounted onto rifles while others are designed to be attached to binoculars.

A variable-powered scope is a scope that adjusts the magnification based on what you’re looking at. For example, if you were looking at something close up, you’d want more magnification than if you were looking at an object far away.

This scope has a magnification range starting at 4x and going all the way up to 2x. It has an objective that is.5 inches in diameter.

A variable power scope with a magnification range starting at 4x and adjusting all the way up to a maximum magnification of 12x. The third number, 50, indicates that the scope has an objective lens diameter of 50mm.

Riflescopes consists of three parts:

  1. Objective lens
  2. Reticle
  3. Eyepiece.
