Que semejanzas y diferencias tiene el microscopio y el de Robert hooke
Sphinxa [80]

Answer:

- Microscopio de Robert Hooke: Aumento de 30X; monocular; con soporte rudimentario; enfoque de objetos transparentes y opacos

- Microscopio óptico actual: más sofisticado, binocular; compuesto por tres sistemas: sistema mecánico, sistema óptico (hasta 1.500 aumentos 1500 X), y sistema de iluminación.

Explanation:

El microscopio óptico fue el primer microscopio y marcó una nueva era en la biología y la medicina, siendo fundamental para la observación de estructuras celulares y subcelulares, lo cual permitió el desarrollo de diversas teorías tales como, por ejemplo, la teoría celular. La característica más importante compartida por los microscopios ópticos es el uso de la luz visible para visualizar las muestras. Los microscopios ópticos rudimentarios fueron popularizados en el siglo XVII, a partir del uso de Galileo Galilei. Posteriormente, en 1665, el científico inglés Robert Hooke usó su microscopio mejorado para observar muestras biológicas. El microscopio de Hooke era monocular y aumentaba la imagen 30 veces (30X), tenía un mejor soporte que los microscopios anteriores más rudimentarios, y podía enfocar tanto objetos transparentes como opacos. Actualmente, los microscopios ópticos están compuestos por tres sistemas: 1-sistema mecánico compuesto por piezas (es decir, una base, platina y brazo) donde están insertadas las lentes, un 2-sistema óptico compuesto por diferentes lentes conocidas como lentes oculares (microscopios binoculares) y lentes objetivos, las cuales permiten el aumento de las imágenes hasta 1.500 (1500X, con uso de aceite de inmersión), y 3-un sistema de iluminación para reflejar, transmitir y regular la intensidad de la luz.
