Microscopes may seem complex, but they are essentially just a series of lenses that magnify tiny images, allowing us to see down to the cellular level

Inschools,twotypesofmicroscopesarecommonlyused:thecompoundmicroscopeandthestereomicroscope.

Compoundmicroscope

Alsoknownasabiologicalmicroscope,thistype usesaseriesoflenses,includingobective lenses(typically4x,10x,40x,and100x), magnifiedfurtherbytheeyepiece(usually10x).

Totalmagnificationiscalculatedbymultiplying theeyepiecemagnificationbytheobective magnification,withschoolrequirementsranging from40xto1000x.Itprovidesatwo-dimensional imagewithabrightlightsourcebeneaththe specimen.

Stereomicroscope
