Compound Light Microscope Change Magnification

The common ocular magnifies ten times marked as 10x.

Compound light microscope change magnification.

This part holds the objective lenses and is able to rotate to change magnification. E simple light microscope it has low magnification because it uses a single lens and the compound light microscope it has a higher magnification compared to the simple microscope because it uses at least two sets of lenses an objective lens and an eyepiece. Look through the binocular eyepieces and adjust the iris diaphragm until the amount of light is satisfactory. It s an upright microscope that produces a two dimensional image and has a higher magnification than a stereoscopic microscope.

To calculate total magnification find the magnification of both the eyepiece and the objective lenses. In this type of microscope there are ocular lenses in the binocular eyepieces and objective lenses in a rotating nosepiece closer to the specimen. These are found on the nosepiece and range from low to high power. In order to ascertain the total magnification when viewing an image with a compound light microscope take the power of the objective lens which is at 4x 10x or 40x and multiply it by the power of the eyepiece which is typically 10x.

If the microscope has a fourth objective lens the magnification will most likely be 100x. A compound light microscope is a type of light microscope that uses a compound lens system meaning it operates through two sets of lenses to magnify the image of a specimen. Rotate the nosepiece so that the objective lens with the lowest level of magnification is directly above the sample reminder. Compound light microscope optics magnification and uses with links to microscopemaster buyer s guides a compound light microscope is a microscope with more than one lens and its own light source.

The standard objective lenses magnify 4x 10x and 40x. More light is better than less light but. Parts of a. Using lower magnifications first helps to select the part of the specimen of interest and then adjust further.
