Viewing infrared sources and polymer infrared optics

A collimated globar source with a broadband output useful to a wavelength as long as 9 micrometers is shown and some characteristics of it are listed and illustrated. An infrared transmitting polymer Fresnel lens is used to focus this source to a small spot. A significant advantage of our polymer material’s virtually identical refractive index across both the visible and infrared regimes for our polymer material is confirmed by observing the stability of back focal length across different wavebands.

Abstract

A collimated globar source with a broadband output useful to a wavelength as long as 9 micrometers is shown and some characteristics of it are listed and illustrated. An infrared transmitting polymer Fresnel lens is used to focus this source to a small spot. A significant advantage of our polymer material’s virtually identical refractive index across both the visible and infrared regimes for our polymer material is confirmed by observing the stability of back focal length across different wavebands.
