Claim 2:
3. The method according to claim 1, wherein said establishing step of said step (a) comprises:
(4.1) drawing a vertical line passing through the coordinate origin O, a straight line L1, and an arc with a radius of R2 on the side of the straight line L1 in the 3D modeling software, wherein the length of the toric mirror is H, the width of the toric mirror is W, the thickness from the geometric center of the toric mirror to the bottom surface is d, the center O1 of the arc is on the same horizontal line as the coordinate origin O, the height of the arc in the vertical direction is greater than the length of the toric mirror H, the length of the center point from the coordinate origin O is the radius of curvature R1 of the toric mirror;
(4.2) constructing the profile of the toric mirror by drawing the profile outer line on the outside of the arc, the distance from the geometric center of the toric mirror to the profile outer line is greater than the thickness d of the toric mirror and the end points on both sides of the arc are respectively connected to the profile outer line to form a closed section;
(4.3) selecting the function of rotating boss and rotating 360° the profile obtained in the step (4.2) as the rotated profile to obtain the CAD model of the toric mirror about the straight line L1;
(4.4) drawing a rectangle, the length of the rectangle is H, the width is W and selecting the stretching and cutting function of the modeling software to obtain an initial model of the toric sub-mirror; and
(4.5) creating a new coordinate system, wherein the new coordinate system takes the geometric center of the initial model of the toric sub-mirror as the coordinate origin O2 and using the two right-angled sides of the toric sub-mirror as the X-axis and Y-axis directions, establishing a new datum plane as reference surface 1, the reference surface 1 is parallel to the XY axes plane of the reference surface 1 and the vertical distance between the reference surface 1 and the geometric center of the toric sub-mirror is d, drawing a rectangular diagram on reference surface 1, the length of the rectangle is H, the width of the rectangle is W and stretching and cutting the rectangular diagram to obtain the bottom plane of the toric sub-mirror to establish the CAD model of the toric sub-mirror.
