Something different for this #WindowFriday - this is a small KBr window (it's transparent to mid-infrared radiation) on a #cryogenic sample holder inside a #vacuum chamber. As you can see, it's cracked, but luckily it still served the purpose as a substrate for growing ice layers on it. We then irradiated these layers in a #laboratory #astrochemistry experiment at #GANIL in Caen, France.
