Air lens vs aspheric surface: a lens design case study

, 2017
We discuss the behavior of air lenses in lens design. The structural aberration coefficients of a thin air lens are derived and compared with their glass thin lens counterpart.

KMT-2022-BLG-0086: Another Binary-lens Binary-source Microlensing Event

The Astronomical Journal
We present the analysis of a microlensing event KMT-2022-BLG-0086 of which the overall light curve is not described by a binary-lens single-source (2L1S) model, which suggests the existence of an extra lens or an extra source.
