This paper reports on the development of transmission mode Transferred Electron (TE) photocathodes with quantum efficiency in excess of 10 % which function in the 950- 1700 nm wavelength range. Photocathode device physics will be briefly covered along with sealed tube photocathode performance. Results will be presented for both imaging and non-imaging detectors. Measured performance characteristics include: photocathode spectral response, dark current, image tube resolution, and image quality data. A brief discussion of system applications of this technology will also be presented. 1
