Types of Objective Lens & Their Functions - MicroscopeSpot
网页2024年2月17日 · The ocular lens typically has a low magnification (10x) and works in combination with the objective lens to achieve a greater magnification power. The objective lens is at the bottom of the eyepiece tube and is responsible for both total magnification of the specimen, as well as the resolving power of the microscope.

What are the Types of Objective Lenses on a Microscope?
网页Low Power Lens (10x) The low power objective lens usually has 10x or 20x magnification. You can identify it by a yellow strip around the lens housing. This objective can be very useful for viewing prepared specimens on slides. It will achieve somewhere around 100x to 200x magnification for a 10x or 20x eyepiece respectively.
What Are the Different Magnifications of Objective Lenses?
网页Low Power Objective (10x) The low power objective lens has more magnification power than the scanning objective lens, and it is one of the most helpful lenses when it comes to observing and analyzing glass slide samples.
Microscope Objectives - Introduction | Olympus LS - Olympus …
网页Lower power objectives have relatively low numerical apertures and are designed to be used dry with only air as the imaging medium between the objective front lens and the cover glass. The maximum theoretical numerical aperture obtainable with air is 1.0, however in practice it is virtually impossible to produce a dry objective with a numerical ...
Properties of Microscope Objectives | Nikon’s MicroscopyU
网页Values range from 0.1 for very low magnification objectives (1x to 4x) to as much as 1.6 for high-performance objectives utilizing specialized immersion oils. As numerical aperture values increase for a series of objectives of the same magnification, we generally observe a greater light-gathering ability and increase in resolution.
