Embodiment Construction
[0022] The invention according to Figure 3 to Figure 10 The structure shown is implemented. first press Figure 10The structure shown is implemented to establish a structural model of the optical system. The material of the ellipsoidal condenser 21 is a nickel base, and the optical surface is directly coated with an aluminum reflective film and a silicon dioxide protective film; the large-curvature spherical collimating mirror 31 is a steel base, which adopts the same process as the ellipsoidal condenser 21; the metal ellipsoidal condenser 21 And the production of the large curvature spherical collimating mirror 31 adopts electroforming process. The convex molds of the ellipsoidal concentrator 21 and the large-curvature spherical collimating mirror 31 are processed by a diamond lathe, and the metal electrolytic deposition principle is used to accurately replicate the shape of the convex molds. The thickness of the obtained ellipsoidal condenser mirror 21 is only 3mm, and t...
