    From pfsmet@mastodon.social on Mastodon: The warmer an object, the more (infrared) radiation being emitted. This is detected by a thermal camera (typ. in the range from 3 to 14µm). Germanium is transparent for this IR (but not in the visible!), making it one of the materials used for # thermal camera # optics . # SummerOfPhysics 20/n
