Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an optical member and a reflection mirror capable of achieving an accurate positional relationship between components.SOLUTION: An optical member 1 includes: a lens barrel 10 that emits generated image light; and a reflection mirror 20 having a curved surface that reflects the image light. In the optical member, a backside face of the curved surface of the reflection mirror 20 has a flat plane 22 for adjusting mutual positional relationship between the lens-barrel 10 and the reflection mirror 20. The curved surface of the reflection mirror 20 is a paraboloid obtained by rotating a parabola around a symmetric axis thereof. The backside face of the curved surface of the reflection mirror 20 has the flat plane 22 substantially vertical to the symmetric axis. Further, the backside face of the curved surface of the reflection mirror 20 has the flat plane 22 vertical to the optical axis of the reflection mirror 20.SELECTED DRAWING: Figure 1
