19 de ago. de 2019 · Em 1830, Joseph Jackson Lister descobriu que quando as lentes eram arranjadas com uma distância adequada entre elas era possível proporcionar uma ampliação eficiente sem desfocar a imagem obtida.
Joseph Jackson Lister was an English amateur opticist whose discoveries played an important role in perfecting the objective lens system of the microscope, elevating that instrument to the status of a serious scientific tool. Lister discovered a method of combining lenses that greatly improved.

Em 1852, Lister fez grandes contribuições à ciência ao usar seu microscópio para examinar a estrutura do olho humano, corroborando a hipótese de que a íris se compunha de fibras de musculatura lisa e que suas ações eram involuntárias, indo contra o que se achava na época. [1]
11 de jan. de 2021 · In 1826, Lister designed possibly the most important optical microscope ever made. It used an achromatic objective lens corrected for chromatic and spherical aberrations, the resulting image was at the time the clearest produced by any microscope.
The microscope has become one of the most recognizable symbols of science. This paper covers the early history of the microscope, starting with use of a simple lens in ancient times, to the first compound microscope circa 1590, up to the microscopes of the 19th century.
1830: Joseph Jackson Lister reduziu a aberração esférica (ou o "efeito cromático") mostrando que várias lentes fracas usadas juntas a certas distâncias proporcionavam uma boa ampliação sem borrar a imagem. Este foi o protótipo do microscópio composto.
8 de abr. de 2018 · Joseph Jackson Lister began studying lenses in the mid-1820s, but his landmark paper, which explained how lenses could be combined in a compound microscope in such a way that chromatic aberration was greatly reduced, was not submitted to the Royal Society until 1830.
