How does a thermal scope work?

Thermal cameras detect temperature by recognizing and capturing different levels of infrared light. This light is invisible to the naked eye, but can be felt as heat if the intensity is high enough. Thermal cameras can see this radiation and convert it to an image that we can then see with our eyes.

Can a thermal scope be used in daylight?

Unlike night-vision scopes that only operate in darkness, thermal scopes can cut through daylight and take your scouting and hunting to a whole new level. But a relatively new technology, thermal imaging, has taken night vision into the next century.

What is thermal imaging in night vision?

Thermal imaging cameras are excellent tools for night vision. They detect thermal radiation and do not need a source of illumination. They produce an image in the darkest of nights and can see through light fog, rain, and smoke (to a certain extent). Thermal imaging cameras make small temperature differences visible.

Can you see deer horns with thermal scope?

Typically, deer have antlers so the thermal should be able to definitively tell you that none of your deer have horns. With a thermal, you can see the antlers when they are growing in and there is blood running in them. When they stop growing and harden you most likely can’t see them, especially at any distance.

Do night vision scopes work during the day?

Since modern traditional night vision optics and scopes also feature a built-in infrared (IR) light that can’t work during the day. The optics don’t overheat nor do they over-expose in daylight. You can also purchase add-ons that protect your binoculars in case you do want to use them during the day.

What is the difference between IR and thermal imaging?

Active IR systems use short wavelength infrared light to illuminate an area of interest. Some of the infrared energy is reflected back to a camera and interpreted to generate an image. Thermal imaging systems use mid- or long wavelength IR energy. Thermal imagers are passive, and only sense differences in heat.
