We display work in progress on a near-infrared tunable bandpass filter for the wide field camera of the Next Generation Space Telescope (NGST) Integrated Science Instrument Module (ISIM). This Demonstration Unit for Low Order Cryogenic Etalon (DULCE), is designed to demonstrate a high efficiency scanning Fabry-Perot etalon operating in interference orders 1-4 at 30 K with a high stability DSP based servo control system. DULCE has heritage in a Northrop Grumman system designed for 1st order operation at 300 K, and is being developed jointly by GSFC and NGC as an option to satisfy NGST requirements. In this application, scanning etalons will illuminate the focal plane arrays with a single order of interference to enable wide field low resolution (50 << R << 200) hyperspectral imaging over a wide range of redshifts. We discuss specific science applications that will be enabled by near-infrared tunable filters.
