Holographically corrected microscope with a large working distance

摘要

We present a design for a microscope with a simple objective lens with a high numerical aperture. The large amounts of aberrations present in the system are removed when a point-source image hologram is recorded. The resultant instrument has a large working distance (>0.17 m) and a moderate field of view over a limited bandwidth. We demonstrate the application of this device to imaging submicrometer details inside a vacuum. [References: 12]
