INFORMATION SYSTEM FOR MULTI-VECTOR RAYTRACING IN ELLIPSOIDAL REFLECTORS
Bulletin of Kyiv Polytechnic Institute. Series Instrument Making, 2023 Due to two focuses, ellipsoidal reflectors are unique reflective optical elements that allow conjugate imaging in two focal planes within their inner cavity. Such reflectors are used in various devices, such as lens telescopes, to achieve high resolution. They have found applications in microscope optical systems to increase the depth of field.

Grazing-incidence ellipsoidal reflector for longitudinally pumping short-wavelength lasers [PDF]
Optics Letters, 1987 We propose using a prolate ellipsoid for collecting and focusing soft-x-ray radiation from a laser-produced plasma to longitudinally pump short-wavelength lasers. Total collection efficiencies greater than 20% at 10 nm into gain regions with aspect ratios of 25 are possible.
