working distance microscope objective
The microscope objective is positioned near the sample specimen or object being observed. Phase Fresnel lens diffraction optical element type A circular polarizing plate and depolarizer are built into T Plan EPI 125.

The objective illustrated in Figure 1 is a 250x long working distance apochromat which contains 14 optical elements that are cemented together into three groups of lens doublets a lens triplet group and three individual internal single-element lenses.
. The objective also has a hemispherical front lens and a meniscus second lens which work synchronously to assist in capturing light. To determine the magnification of your microscope multiply the magnification of the eyepiece lens by that of the objective lens. Usually starting from low.
These lenses are located on the rotating nosepiece and are the most crucial in magnifying the specimen in order to see it bigger better and in more detail. Circular polarizing plate can be attacheddetached CFI60 Objectives. Long Working Distance Type.
It has a very important role in imaging as it forms the first magnified image of the sample. There are different classifications and specifications of objective lenses. The numerical aperture NA of the objective indicates its ability to gather light and largely determines the microscopes resolution.
For advanced micro-imaging software that allows you to seamlessly acquire process and measure images our Olympus Stream is the perfect model for you. If your stereo microscope has a rotating objective turret for fixed-power microscopes turn it to the objective you want to use. The objective lens is a critical part of the microscope optics.
TU Plan BD ELWD Long Working Distance Universal Plan Semi-apochromat 20X. For example the total magnification for 10x eyepiece and 2x objective lenses is 20x 102. A compound microscope will normally have around three to five objective lenses each with a magnification of 4x to 100x.
