Title: Reflecting and refracting optical lens and its manufacture
Inventor: TAKASHIMA YUZURU
IPC: B81B1/00
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To obtain a reflecting and refracting optical lens which has no chromatic aberration by using a convexo-concave lens which has a specified curvature. SOLUTION: A meniscus lens 20a which has one surface made concave and its opposite surface made convex is used as the reflecting and refracting optical lens 20. A 1st reflecting surface 21 is formed on the convex surface of this meniscus lens 20a and a 2nd reflecting surface is formed on the concave surface. On the remaining surfaces of those concave and convex surfaces where the reflecting surfaces are not formed, a 1st refracting surface 23 is formed on the concave surface side and a 2nd refracting surface 24 is formed on the convex surface side. At this time, those concave and convex surfaces are so formed that the ratio of the radii of curvature of those concave and convex surfaces is 0.8 to 1.2.  Thus, the reflecting and refracting optical lens 20 is formed of such surfaces of curvature that the ratio (R2 /R1 ) of the radii of curvature of the convex surface and concave surface is 0.8 to 1.2, so that no chromatic aberration is generated.
