Patent ID: 6992293

Claim:
A real-time infrared chemical imaging spectroscopic apparatus, in cooperation with a target, comprising: a light source for emitting infrared radiation; a first focusing lens for receiving and focusing said infrared radiation; a monochromator for receiving and dispersing said infrared radiation being converged by means of said first focusing lens to form a narrow-bandwidth infrared radiation having a predetermined wavelength; a second focusing lens for receiving and transforming said narrow bandwidth infrared radiation into collimated narrow-bandwidth infrared radiation; a sample stage for receiving said collimated narrow-bandwidth infrared radiation so that said collimated narrow-bandwidth infrared radiation pass through a target mounted on said sample stage; wherein said target absorbs said collimated narrow-bandwidth infrared radiation and emits thermal radiation; a Cassegrain objective for collecting said thermal radiation; and an IR camera for receiving said thermal radiation collected by said Cassegrain objective to form an image.
