“…8 Subsequently, NASA funded both the scientific and technical concept as Pre-Phase A study, 9 together with an exploration of enabling MEMS technology. 10,11 The development of new technology was made necessary by the particular requirements of the JWST instrument (slit size ~100 micron, cryogenic capability, contrast 2000:1 or higher) which made the DMDs developed by Texas Instruments (TI) for commercial projection systems (Figure 2) unsuitable for JWST. At the same time, the NASA Goddard Space Flight Center (GSFC), the Space Telescope Science Institute and the Kitt Peak National Observatory jointly funded the development of IRMOS, 12,13,14 a multi-object near-IR spectrograph based on a TI DMD of 848×600 elements.…”

A long-standing problem of astrophysical research is how to simultaneously obtain spectra of thousands of sources randomly positioned in the field of view of a telescope. Digital Micromirror Devices, used as optical switches, provide a most powerful solution allowing to design a new generation of instruments with unprecedented capabilities. We illustrate the key factors (opto-mechanical, cryo-thermal, cosmic radiation environment,...) that constrain the design of DMD-based multi-object spectrographs, with particular emphasis on the IR spectroscopic channel onboard the EUCLID mission, currently considered by the European Space Agency for a 2017 launch date.Comment: 10 pages, Proc.

“…We first proposed this concept during the concept development phase of NASA's Next Generation Space Telescope (now James Webb Space Telescope --JWST) in early 1996 1 and were subsequently funded by NASA to develop both the scientific and technical concept as a Pre-Phase A study 2,3 and to explore the enabling MEMS technology. 4 JWST ultimately selected a MEMS based approach for the JWST Near Infrared Spectrometer (NIRSPEC -assigned to the European Space Agency as part of its contribution to JWST) that uses a MEMS based micro-shutter array rather than our MMA reflective design (see presentations by Moseley et al)…”

The Infrared Multi-Object Spectrometer (IRMOS) is an innovative near-IR instrument employing an array of MEMS micro mirrors for focal plane target selection. IRMOS is a joint project of the Space Telescope Science Institute, the NASA James Webb Space Telescope, and the Kitt Peak National Observatory and will shortly become available to the community at Kitt Peak. IRMOS uses a Texas Instruments 848x600 element DMD as a micro mirror array to synthesize slits to obtain up to 100 simultaneous spectra. It provides R~300, 1000, and 3000 spectroscopy in the J, H, and K bands plus R~1000 in Z together with imaging in all bands. Designed for the KPNO 4 and 2.1-meter telescopes, IRMOS will provide 3x2 and 6x4 arc minute fields of view on these telescopes. We describe the design and status of IRMOS, summarize its expected performance, and present early test data from system level lab tests.

“…Here a reconfigurable field selector will be necessary. In its most variable realization such a reconfigurable field selector is a two-dimensional MEMS device such as a micro mirror 8,9 or micro shutter 10,11 array. Another possibility for the realization of a two-dimensional spatial light modulator is given by slit positioning systems.…”

Multi object spectrometers measure spectra of multiple objects simultaneously. Besides others, e.g. fiber positioning systems, there is a class of multi object spectrometers which is based on a dispersing imaging optics in connection with a slit masks. Two considered approaches for reconfigurable slit masks are two-dimensional MEMS arrays, such as micro mirror or micro shutter arrays, and slit positioning devices. After an introduction to multi object spectrometry with dispersing imaging optics we calculate the effective multiplex capabilities of multi object spectrometers based on 2D MEMS and on slit positioning devices for randomly distributed objects. The observation efficiency of multi object spectrometers based on 2D MEMS is compared to integral field spectrometers and to multi object spectrometers based on slit positioning devices. We find that for typical applications the efficiency of the slit positioning approach is nearly as good as the efficiency of the 2D MEMS approach. This makes slit positioning systems a serious alternative solution to 2D MEMS devices as long as they are easier to get.
