Written by Kane Dane

A Thor thermal scope is by far the coolest optical device you can install on a weapon and they have proven themselves again and again as an innovative leader in low light imaging.

Thor thermal scopes feature multiple color pallets, digital reticle, and settings as well as recording capabilities which by means of a special portable digital recorder you can now easily record your hunts to show friends and family. This is helpful in perimeter security, where simply scouting a possible invader is extremely important.

Due to the fact that thermal scopes read and reproduce on display thermal signature of an object, you cannot expect to see all details of the object you are looking at.  You will only see an outline of items which have contrasting temperatures.

How Does Thermal Imaging Work?

Thermal imaging allows those who utilize it to see the seemingly invisible. Since the majority of objects in the natural world emit heat in one form or another, the scopes capture the differences in heat between the target and its immediate environment.

The focused light ray is examined by a phased array of infrared detector elements. The infrared detector elements generate a full temperature pattern known as a thermogram.The thermogram created by the infrared detector elements is converted into electric signals through thousands of sensors on the array which create a video image. Even in challenging weather conditions or complete darkness, thermal imaging gives users the ability to see the unseen.


The scope is rich with features and options making it the best value of any comparable scope on the market. Once ranged, the scope automatically adjusts the point of impact. No more black reticles on a black and white screen Thor features a color OLED display giving you a sharp color reticle every time.
