Point Source Microscope - Used for the alignment of optical systems and tests. The PSM is also invaluable for aligning aspheric optics, including off-axis aspheres. Because the PSM not only locates point images but shows the image shape, it is used to aid in holding the image in the correct translational location while the asphere is adjusted to reduce the alignment aberrations to zero. Additional information and technical papers available.
