Apparatus for mounting a panoramic mirror
The present invention is directed to a mounting apparatus for mounting a panoramic mirror in front of the focal point of a camera. The mounting apparatus comprises a conical optical stage configured to contact the mirror at an end point along the longitudinal axis. An optical masking spike is also disclosed which can be disposed along the longitudinal axis and extend at least partially into the interior of the conical optical stage. The conical optical stage and optical masking spike provide improved stability of the overall optic and reduce unwanted glare in images reflected to the camera.
1. An apparatus for mounting a panoramic mirror having an outer mirror diameter, comprising a generally conical optical stage including a substantially clear material and having a first end having a first stage diameter structured to be fastened to a panoramic mirror and a second end having a second stage diameter, wherein the second diameter is greater than the first diameter, the first diameter is less than the outer mirror diameter and a reflected image from the panoramic mirror passes through the substantially clear material of the optical stage.
2. The apparatus of claim 1 , wherein the optical stage has a convex conical shape.
3. The apparatus of claim 1 , wherein the optical stage has a concave conical shape.
4. The apparatus of claim 1 , wherein the optical stage comprises a substantially transparent material.
5. The apparatus of claim 1 , wherein the optical stage comprises at least one side extending between the first end and the second end, the side forming an angle with the longitudinal axis of the optical stage of from 20 degrees to 70 degrees.
6. The apparatus of claim 5 , wherein the angle is from 40 degrees to 50 degrees.
7. The apparatus of claim 1 , wherein the first end is truncated.
8. The apparatus of claim 1 , further comprising an optical masking spike disposed along a longitudinal axis of the optical stage and extending from the first end of the optical stage at least partially into an interior of the optical stage.
9. The apparatus of claim 8 , wherein the masking spike extends from the first end of the optical stage to the second end of the optical stage.
10. The apparatus of claim 8 , wherein the masking spike extends from the first end of the optical stage along the longitudinal axis to an area beyond the second end of the optical stage.
11. The apparatus of claim 8 , wherein the masking spike comprises a first end having a first diameter disposed adjacent the first end of the conical optical stage and a second end having a second diameter, wherein the second diameter is less than the first diameter.
12. The apparatus of claim 8 , wherein the masking spike comprises a light absorbing material.
13. The apparatus of claim 1 , wherein the first end of the optical stage is fastened to an end portion of the mirror along a longitudinal axis of the mirror.
