Point Source Microscope by Optical Perspective Group

The Point Source Microscope (PSM) was originally designed to aid in the alignment of a centered optical system whose elements included spherical lenses, toroidal lenses and spherical mirror segments used off-axis.  Alignment meant putting the centers of curvature of all these surfaces on a common axis.

PSM Applications

• Mechanically locate centers of curvatures and foci of on-axis beams

• Locates point images and shows the image shape.

• Aids in holding the image in the correct translational location while the asphere is adjusted to reduce the alignment aberration to zero.

• Measurement of paraxial lens parameters for debugging and reverse engineering

• Sensitive to image shape—it can be used for inspection of optics and the measurement of the surface radius of curvature.

• While not as sensitive as an interferometer, the PSM can see wavefront errors of a quarter wave or less. 

• For shops without access to an interferometer, this can be useful if the quality of an optical element is questionable or there is a concern that the mounting has distorted the optics.

• Aligning holograms to null optics for aspheric testing

• Aligning machined off-axis metal mirrors for terahertz (sub-millimeter) optical systems

• Aligning image slicer mirror arrays in astronomical spectrophraphs

• Aligning three-dimensional systems

• Aligning off-axis and telescope systems

• Aligning mold cavities for plastic cell phone camera lenses

• Aligning aspheric optics, including off-axis aspheres.
