Thread: Thermal knowledge?

The 2 main factors you should look at are the thermal cores resolution - generally these days its .17u (thats the spacing between pixels, lower is better, means more pixels per square inch) older/cheaper models are generally .25u and the new standard is .12 (each step is around 30% better which is a lot) and the lens length which is your optical magnification

The size of the core/lens will effect the overall Field of view and number of pixels on the target as well; Others are factors like lens quality (f/1 is ideal etc) core quality, image processing, sensitivity etc

that pulsar unit is a 38mm lens (f1.2) with a .17 core - So to get the improvements you are after you may need to look at something with a longer lens to get the magnification you need for a more defined image
