• ¿Qué factores son clave para el manejo correcto del microscopio compuesto u óptico cuando se observa una muestra?
leonid [27]

Answer:

1-Tener en cuenta el tamaño del objeto a observar para utilizar la lente con el aumento correcto (es decir, 10 X, 40 X o 100 X)

2-Utilizar aceite de inmersión para ver objetos en 100 X

Explanation:

El microscopio óptico posee lentes (ocular y objetivo) los cuales permiten ampliar la imagen del objeto observado. El microscopio simple y el compuesto representan dos tipos de microscopios ópticos. El microscopio compuesto es aquel que utiliza más de una lente para aumentar la imagen observada, mientras que el microscopio simple usa una sola lente (la cual se denomina lupa). El microscopio óptico puede utilizar un aceite de inmersión que permite aumentar la resolución de la imagen a través de la inmersión de la lente objetivo. Es importante señalar que durante el enfocado de la muestra se debe tener sumo cuidado de no acercar demasiado la lente a la superficie del cubreobjeto, ya que esta puede dañarse.
