Concept 2 Design of MISC (less capable than Concept 1)

1. Basic Concept

- Type of MIR Transit Spectrograph; Densified Pupil Spectrometer

2. Configuration

[1] MISC Wide Field Imager (WFI)
[2] MISC Transit Spectrometer (TRA)

3. Resources

Detectors (Assumptions)

- 3 x "Si:As 2kx2k Detector Array [30µm/pix]" for WFI-S1, WFI-S2, WFI-L
- 2 x "HgCdTe 2kx2k Detector Array (30K)" for TRA-S and TRA-M
- 1 x "Si:As 2kx2k Detector Array" for TRA-L
