| Shack-Hartmann wavefront sensor test of Multi-component lens |
|
 |
|
Setup :
In the above configuration, diverging light from Optino falls on the lens L under test. It is made
parallel by it,
and falls on a flat mirror M (which should be of a high quality, say l /4, l /10 or l /20, depending on the accuracy required for testing the lens L). The light from the mirror M
returns to Optino, and passed to the SH system.
The aberrations of the SH system itself are removed taking a calibration frame of a small high quality (like for the flat mirror above) spherical mirror instead of the lens L.
