Quick answer: Nocpix splits its handheld thermal into three ranges — LUMI (compact and value), VISTA (premium monoculars) and QUEST (thermal binoculars) — and the same model code applies as the scopes: the letter is the sensor tier (P = 256×192, L = 384×288, H = 640×512, S = 1280×1024),...

Quick answer: Nocpix builds one of the most complete thermal ranges in Australia, and the model codes make the whole line-up easy to read once you know them. The letter in a name is the sensor tier — P = 256×192, L = 384×288, H = 640×512, S = 1280×1024...

On a thermal scope, base magnification and field of view are two sides of the same number — both are fixed by the objective lens, the sensor size and the display, and as one goes up the other goes down. Base (optical) magnification is the truest, sharpest view the scope...

Pixel pitch is the physical spacing between the pixels on a thermal sensor, measured in microns (µm) — and for the same resolution and lens, a tighter 12µm pitch gives a narrower field of view, higher base magnification and more pixels on a distant target, while a wider 17µm pitch...
