Abstract :
A Winston cone is used to concentrate the emitted radiation of a mid-infrared LED onto a small spot on the side of one prong of a quartz tuning fork acting as a detector. The Winston cone is used as an absorption cell as well, thus providing a very compact and cost efficient mid-infrared sensing system.
