What is the difference between thermal and infrared scopes?
Infrared scope systems reflect infrared energy to produce images and use short wavelength infrared light for illumination while thermal imaging scope systems sense heat changes and use mid- or long-wavelength IR energy.
In situations where there is little to no distinction between night and day, it’s crucial to establish visibility while remaining invisible. For this, thermal and infrared scopes were created. Unlike the standard scopes that depend on ambient light to create an image, these scopes depend on infrared waves that are produced by any object that emits heat.
Infrared Scopes
If you are observing objects that are in a group, the difference in temperature between those objects will provide the contrast you need to identify each individual object. This makes infrared scopes suitable for use even in total darkness.
Moreover, you can use an infrared scope to spot an object that’s partially or fully hidden. If it’s a person that’s hiding inside a cardboard box or an animal that’s hiding behind a bush, it can be difficult for you to see it with your naked eyes when it’s dark. But an infrared scope will detect their heat signature and make them clearly visible to you.
Over the years, infrared sensor technology has seen major improvements. Before, these devices were primarily used by the military and law enforcement. In modern times, they are now used by hunters and tactical shooters who would like to still continue with their shooting expedition even when the sun sets. They are readily available and at a cheaper price so you don’t have to break the bank to get one.
To help you understand how infrared scopes are beneficial, let’s now look at their uses.
Hunting
Most game that hunters hunt are nocturnal. This means that they will be more active and easier to hunt when the sun sets. Because of the dark, hunting these animals gets hard if you don’t have a scope that improves your visibility. Having an infrared scope will help you spot the game immediately even when they are hiding behind thick bushes.
Security and Surveillance
An infrared scope comes in handy during nighttime surveillance. When you are surveilling your homestead at night, you no longer have to be scared of bumping into predators that can attack you. If you have a large, open track of land, you will sleep peacefully knowing that there are no creatures or characters lurking around.
Military Use
An infrared scope is also helpful to soldiers. First, they can use the IR illuminator to read the map when they are on the battlefield. An infrared scope will also help them see where their enemies are hiding while staying invisible to them.
Personal Safety
If you like to take walks late in the evening, you may want to check if there are any predators before you head out. This is particularly the case if you live in an area that’s secluded that’s filled with wild animals.
Thermal Scopes
Thermal scopes are almost similar to infrared scopes. They use temperature instead of light to form an image.
Scopes with thermal imaging technology depend on heat energy to create an image. This technology detects different heat energies that come from the surrounding and create high-end images.
What set’s them apart from their infrared counterparts is that they are able to work for long distances. So, they will capture heat signals from any object regardless of the distance or the light conditions.

Advantages of using Thermal Scopes
Taking Temperature
Thermal scopes work by picking up the smallest differences in temperature and using it to create an image. They will form a picture of anything as long as its temperature is different from the normal surrounding temperatures. It could be an animal, a person, a rock, or any object that has some thermal energy. This is also what is used on thermal imagers and thermal cameras
The sensors found in thermal scopes can detect thermal differences as low as 0.01°. When hunting, you will be able to differentiate the game and even pick up small blood drops when you are tracking a freshly shot animal.
See Through Bush, Fog, and Smoke
Since thermal scopes read temperature differences to form an image, they will help you see through certain impediments such as bush and fog.
If you are hunting in wet and foggy conditions, a thermal scope will help you spot your targets swiftly. Moreover, since a thermal scope can to some degree see through smoke and debris, they help firefighters to rescue people who may have passed out because of inhaling too much smoke. It will also show a firefighter if the door is too hot so they can look for an alternative way to get into the house.
Scouting
Modern thermal scopes are a perfect companion when scouting. They are highly accurate and provide much better imaging than their predecessors. Thanks to their increased accuracy, you will be able to sight-in as many units as possible with only one shot.
Dual Functionality
Thermal scopes are designed to be used at night and during the day as well. Since they use temperature instead of light, they will give the same image quality whether you are using them at night or in broad daylight.
If you are using the thermal scope for hunting, you’ll find the dual functionality handy. It means that you don’t have to cut short your hunting trip when the sun starts to set. Besides, you won’t need to swap optics and possibly lose your zero when you want to hunt predators or hit the range during the day.
Surveillance
You can also use a thermal scope for surveillance. Since it can see through smoke and fog, it makes one of the most effective tools for surveillance. Plus, it works equally well during the day and at night.
FAQ
Does Thermal Imaging use infrared?
Although both of these technologies function almost in a similar way, and are sometimes used interchangeably, it’s untrue that thermal imaging uses infrared. Infrared is a form of light emitted by molecules with a color that’s invincible to the human eye. Thermal imaging however uses heat to identify objects not light.
Final Thoughts
Thermal scopes and infrared scopes have similar uses but also with some difference between them. So, when you have to choose any one of them, make sure that you choose a product that meets all your needs. Also, consider where and when you intend to use the scope as it will help you choose right.
