Being able to see in the dark is a great help for hunters, and also has its uses in military application. Things are even better when you can not only see in the dark, but can also detect the heat signals given off by living – and other – things. Attaching a night scope to a rifle, for example, or a camera is one thing, but attaching a thermal imaging scope is quite another.
You may have seen footage, or read about, the police using thermal imaging cameras on their search helicopters. These are sophisticated devices that deliver excellent results and help in many ways, but how do they work, and what advantages do they have in civilian usage?
The world of optics is one that has seen much development in recent years, not least with the advent of digital technology. Thermal imaging scopes have taken advantage of this, and the result is a very sophisticated selection of items that have many different uses. How does a thermal imaging scope work, and what will you experience when you use one? Let’s have a look in greater detail.
How it Works
The concept behind a thermal imaging scope is actually quite simple, and such devices have been used for many decades in some form or other. All living things give off a certain amount of heat – as do buildings and other objects – and the digital thermal imaging scope works by isolating this heat using clever technology to provide an image that the user can recognise.
Scopes use different images to present the results. In some cases, the image can appear in bright fluorescent colours. In others, it could be an easily recognisable shape. Which you prefer will obviously influence your choice of digital thermal imaging scope, and there is plenty of choice – turn to Thermal Imagers to find one for you!
The purpose of your scope will influence the model you want; this will also depend upon your budget and needs. For a basic hunting thermal imaging scope there are plenty to choose from at sensible prices, so here’s a few things to look for when choosing your digital thermal imaging scope.
Features to Look For
When looking at digital thermal imaging scopes, it is important to know what they do, and what you need to look for. Some are much more sophisticated than others, and also much more expensive.
If you have a budget set, you can start looking at scopes that fit within your range. One of the first things you need to consider is how powerful a digital thermal imaging scope you need. You need a zoom function, and it is important that you find one with a genuine digital zoom function.
This is often called ‘e-zoom’ and it is important because it means you get the magnification with losing any of the clarity. Check the specifications before you buy, as not all scopes have this facility – Powerpoint Engineering can again help you here.
If you are using your scope on a rifle or camera, you will also want one that is suitably light in weight. You don’t want to be lugging around anything heavier than is necessary. Also, check out the battery life; all scopes need a built-in battery to function, and it will need charging on a regular basis.
You can even find digital thermal imaging scopes that have an automatic video feature; this starts recording at the very moment you take a shot. Such features are worth checking out in advance.
Whatever you want from your digital thermal imaging scope, be sure to check out all the information you can on the vast range available, and make sure you get the right one for you.
