origin of the word "microscope"

Microscope

designed to produce magnified visual or photographic images of objects too small to be seen by naked eye

Anton Van Leeuwenhoek

who used the early microscope that was described as "simple", had only one lens

Janssen brothers

they invented the compound microscope in 1995

Light Microscope

type of microscope that permits the viewing of opaque objects and can magnify up to 30 times.

Compound Microscope

optical instrument with two lenses, the objectives and the eyepiece or ocular.

Monocular

type of compound microscope with only one eyepiece/ocular

Binocular

type of compound microscope with two eyepieces

Mechanical, Magnifying, Illuminating

3 major parts of compound microscope

mechanical part of compound microscope where microscope firmly rest.

Arm

mechanical part of compound microscope serves as a handle for carrying the microscope.

Stage

mechanical part of compound microscope that holds/supports the slide;

Pillar

mechanical part of compound microscope the post of the base where the arm is attached.

Stage Clips
