I think that every #physics department needs at least one infrared camera. There's a great deal on the @thermalmaster P4 (for android).

It's on sale! Use discount code: THERMALBF10

If you have an iOS device, there's also the ThermalMaster P3 (I really like this one). It doesn't have the dual IR/visible camera but it does have adjustable focus. It's still great. Use code THERMALBF10
