- 3 mirror anastigmat
- Elliptical f/1.2 Primary Mirror (PM)
- Hyperbolic Secondary Mirror (SM) creates f/9 intermediate image (6 DOF)
- Elliptical Tertiary Mirror (TM) images pupil at Flat Fine Steering Mirror (FSM)
Primary Mirror Segment Assembly (PMSA) = Mirror + Actuators Primary Mirror Segment Assembly (PMSA) = Mirror + Actuators
EDU mirror is designated Pathfinder mirror: EDU mirror is designated Pathfinder mirror:
JWST optics are designed to be diffraction-limited at a wavelength of 2 μm JWST optics are designed to be diffraction-limited at a wavelength of 2 μm Preliminary simulations of the OTE using A4 flight mirror data as a template for the primary mirror - F444W, F200W, F115W, & F070W
- NIRCam pixels are 0.032” (SW) and 0.065” (LW)
