WebJun 26, 2006 · An achromatizing lens has been designed for the human eye in the near infrared range, from 700 to 900 nm, for retinal imaging purposes. Analysis of the performance of the lens, including tolerance to misalignments, has been mathematically accomplished by using an existing eye model. WebSep 1, 2024 · The critical values of the parasitic aberration coefficients are calculated using a wave-optical method, which determines the stability of the deflection system, the lens doublet, and the hexapoles. The derived properties of the parasitic aberrations are used in an alignment procedure of the system with the corrector. Introduction

WebMerciless ones, also called mindbenders, mind-squids, mindstealers, and zoatroids, are octopus-like cyclopean parasitic aberrations related to the Old Gods, primarily found alongside naga forces. They are capable of attaching themselves to (and/or devouring) the heads of sapient beings in order to enslave them. Part of the process involves using an …
WebMar 2, 1991 · It is extremely unlikely that the observed parasitic aberration could result from mechanical misalignments, since any random misalignment would certainly also introduce parasitic sextupole field components, which would most likely dominate over the effect of the para- sitic octupole components. WebThe adjective parasitic is mainly a scientific term for talking about an organism that lives on a host, taking what it needs to stay alive while often injuring the host.
