A microscope that maintains focus when the objective magnification is increased is called.

Parfocal.

The total magnification achieved when using a 100x oil immersion lens with 10x binocular eye pieces is.

The total magnification achieved when using a 100x oil immersion lens with 10x binocular eye pieces is.

**1000x**.So, what is 100x magnification?

The eyepiece produces a power of 10x and the objective lens can produce various different powers, so if it were to produce a power of

**100x**, the final**magnification**would be 1000x (10 x 100). So this would mean that to the naked eye, the image would appear 1000 times larger than it actually is.How do you calculate the total magnification?

To figure the

**total magnification**of an image that you are viewing through the microscope is really quite simple. To get the**total magnification**take the power of the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X.What is the maximum total magnification for a light microscope?

The actual power or magnification of a compound optical microscope is the product of the powers of the ocular (eyepiece) and the objective lens. The maximum normal magnifications of the ocular and objective are

**10×**and**100×**respectively, giving a final magnification of**1,000×**.
