What's its maximum useful magnification? Useful magnification, férgek egy gyermekév tünetei I see it, is the same thing as optical magnification and it depends on objective's aperture? Levenhuk Customer Service: The numerical aperture NA of a microscope objective is a measure of its ability to gather light and resolve fine details of observed object.

It is defined by a complex mathematical formula, and is associated with an angular aperture of the lens and the refractive index of the medium between the lens and the specimen. To obtain the best image quality you will need a condenser with a numerical aperture that matches or exceeds a numerical aperture of the microscope objective lens with the highest magnification.

The numerical aperture is only important for microscopes with high magnification. Levenhuk Giardia a model organism is equipped with Abbe condenser with the largest numerical aperture of 1. Maximum useful magnification is x. Magnification is calculated according to this formula: objective lens magnification x eyepiece magnification.

Craig : And one szivféreg ellen question: what objects I won't be able to observe with a microscope that doesn't allow observing using dark field method? Levenhuk Customer Service: Dark field observations allow you to see lots of details that can not be seen when observing in bright field.
