Inside the tube

Five things happen between the animal and your eye, and they happen in this order.

1. 01

   The heat leaves the animal

   Anything above absolute zero gives off infrared radiation. The hotter the body, the harder it throws — and the easier it is to pick out of the scrub.

2. 02

   Germanium gathers it

   Ordinary glass blocks infrared outright. Thermal objectives are cut from germanium, which passes the radiation straight through to the detector.

3. 03

   The microbolometer reads it

   A grid of vanadium-oxide pixels, each one shifting its electrical resistance as heat lands on it. That shift, pixel by pixel, is your image.

4. 04

   The processor maps it

   Image Pro turns those raw resistance readings into a clean temperature map, fifty frames a second, so moving game stays sharp instead of smearing.

5. 05

   The OLED shows it

   Hot reads bright, cold reads dark. Swap palettes when the contrast suits the country better — black hot over wet grass, white hot over bare paddock.

The numbers that matter

Four figures on every spec sheet decide how far and how clearly you'll see.
