The best low-light hunting rifle scopes will gather lots of light and use it efficiently. There are some criteria that make some scopes better than others in low-light situations, you’ll learn about these criteria and why the scopes in this post are the best low-light hunting scopes on the market. The scopes below are sorted by price for your convenience.

Factors That Influence Scope Low-Light Capabilities:

  • Objective Lens Size
  • Magnification
  • Exit Pupil Size
  • Glass-Quality
  • Lens Coatings
  • Max Human Eye Dilation

What Makes A Low-Light Hunting Scope Good?

The biggest factors that determine if a scope is going to be good in low-light situations are listed below:

Objective Lens Size

The objective lens size is how big the lens is (in mm) opposite the eyepiece. The bigger the objective lens is, the more light a scope is able to gather. So for low-light situations, you’ll want to get a big objective lens. You’ll find most of the scopes in this review have an objective lens between 44-56mm. Large objective lenses like these will easily allow you to see in twilight and even in the dark fairly well with good moonlight.

Magnification

Magnification also determines how much light will enter your scope. At 2.5x a scope will be able to let more light in than at 10x because as you zoom in less light is able to enter the scope. Exit pupil size uses both objective lens size and magnification to give you a good idea of how much light can enter the scope (more on exit pupil size below).

Exit Pupil Size

Both the magnification and objective lens size play a role in how much light a rifle scope is able to gather. As magnification increases, light gathering decreases. Also, as objective lens size increase so does the scope’s light-gathering capabilities. It is easier to just use exit pupil size, which is the ratio of objective lens size to magnification.

For example, if you have a 2.5-10×56 rifle scope you would divide the objective lens size (56mm) by the magnification (2.5-10). For example, at 2.5 magnification you would do 56÷2.5=22.4mm which is a lot of light.

When you zoom in 10x you would do 56÷10=5.6. As you can see the more you zoom in the less light the scope is able to gather.

For example, if you compared a 2.5-10×56 to a more common 3-9×40 you would see a clear difference:

Rifle Scope Specifications 3-9x40 2.5-10x56
Lowest Magnification 40÷3= 13.33mm 56÷2.5= 22.4mm
Max Magnification 40÷9=4.44mm 56÷10= 5.6mm

Glass-Quality

You can have a big objective lens and tube size but without good glass quality, the light transmission through the glass will suffer. For this reason, it is important to buy scopes from reputable rifle scope brands that offer quality light transmission. Sometimes brands will state the % light transmission of a rifle scope.

Lens Coatings

Lens coatings increase light transmission by reducing the amount of light reflection. Reducing light reflection allows light that would otherwise bounce off the glass to enter the scope, increasing light transmission. So lens coatings help greatly in both low-light and intense-light situations.

Considerations For Low-Light Scopes

The Human Eye’s Ability To Dilate

However, the human eye can only dilate to about 8mm at best so there is no point in an exit pupil size larger than this. So a larger objective lens is primarily to help bring maximum light at the mid-to-higher magnification ranges, not so much at the lower zoom ranges.

Scope Tube Size

Scope tube size does not make a difference in the light-gathering capabilities of rifle scopes. It is easier to make this mistake because you would think that a bigger tube size allows more light into the scope, however, this is not the case. The reason for a larger tube size is simply to have more room in the internals of a rifle scope for windage and elevation adjustments.
