Objective lenses are the most complex part of the microscope due to their multi-element design. It is this complexity that makes the objectives the most important components of the microscope.
Purpose and Function of Objective Lenses Objective lenses are the primary lenses closest to the object being looked at in a microscope. They are like the eyes of the microscope. Additionally, these lenses gather light from the specimen (the tiny thing you want to see) and magnify it, making...
Buying a microscope can be confusing when looking at the microscope objective types. You will notice terms like Achromatic, Sem-Plan, Plan, Super High Contrast, PlanApo, Apochromatic, etc. But what do these terms mean? These terms help identify the quality of the microscope objective lenses, ...
A common example of a simple microscope is a handheld magnifying glass. 2. Compound Microscope A compound microscope is widely used in biological and medical laboratories for studying microscopic organisms and cell structures. It uses two sets of lenses, the objective lens near the specimen and the...
These biological inverted microscopes are used to view living samples that are in a petri dish. An inverted microscope allows the user to place the petri dish on a flat stage, with the objective lenses housed beneath the stage. Inverted microscopes are used for in-vitro fertilization, live ...
What are lenses?A lens is a transparent piece of glass or plastic with at least one curved surface. It gets its name from the Latin word for "lentil" (a type of pulse used in cooking), but don't let that confuse you. There's no real reason for this other than that the most ...
The Compound Light MicroscopeCommonly binocular (two eyepieces), the compound light microscope, combines the power of lenses and light to enlarge the subject being viewed. Typically, the eyepiece itself allows for 10X or 15X magnification and when combined with the three or four objective lenses, ...
The tube with the lenses can be moved parallel to the axis towards the object or away from it. There is an arrangement to change the distance between the objective and the eyepiece.Working principle: Fig. illustrates the working principle of the compound microscope. Fo and Fe are the foci ...
2. Compound Microscope Compound Microscopeis a type of microscope that used visible light for illumination and multiple lenses system for magnification of specimen. Generally, it consists of two lenses; objective lens and ocular lens. It can magnify images up to 1000X. Its magnifying power is equa...
