Stray light entrance pupil: an efficient tool for stray light characterization

, 2020
peer reviewedStray light represents a major performance limitation for optical instruments. Analyses are done with ray-tracing software to evaluate the stray light performances of a design and, if necessary, improve it before manufacturing.

NuSTAR spectral analysis beyond 79 keV with stray light [PDF]

, 2022
Due to the structure of the NuSTAR telescope, photons at a large off axis (>1°) can reach the detectors directly (stray light), without passing through the instrument optics.

General design algorithm for stray light suppression of a panoramic annular system

Optics Express, 2023
In this work, a universal algorithm for designing a panoramic annular lens (PAL) system free from stray light is proposed. The impact of a given stray light path to the optical system could be estimated without running a full stray light analysis process, which allows designers to eliminate troublesome stray light paths by optimizing lens parameters at
