SPST208 - Four mirrors plus lens after chopper, some attempt to constrain quality of Lyot stop illumination.

Figure 7 - Detail of Fig.1 near dewar. Disks near Lyot stop are 250 mm diameter, 50 mm apart.
Figure 8 - Detail of Fig. 2 near detector. Lens is silicon, 400 mm
diameter, plano- convex.
Figure 9 - detail of Fig 3 near detector

Figure 11 - front view, field 10
Figure 12 --- RMS wavefront error vs. field
Figure 13 --- primary illumination, central field
Figure 14 - primary illumination, field 4. This field is "typical" of most of the detector area.
Figure 15 - Primary illumination, field 10. This is the worst one. This field participates in a cuspy peculiarity at mirror 5 that is corrected in subsequent models.
