Three-Mirrors Anastigmat (TMA) Telescope<br />
- An unobstructed three-mirror anastigmat (TMA) combination<br />
(no coma) O3 acts as the primary objective and forms an<br />
O2 <br />
aberration-free image of the diffraction fringe surrounding<br />
M3<br />
the<br />
external occulter, thus allowing its optimal blocking by the<br />
Focal inner Plane occulter. <br />
- f = 800 mm; F/8 (M1 useful: Ø100).<br />
- The objective<br />

of the pupil at the Lyot stop. The collimated beam<br />
leaving O2 goes through the LCTP filter.<br />
- The final image is formed by the objective O3 on the CCD<br />
M1 <br />
detector such that a circular field of view with a radius of 3 R ⊙<br />
forms an inscribed circle on the 2k x 2k pixel detector where<br />
one pixel subtends 2.5 arcsec in the corona. <br />
