## How do you find the 100x magnification?

Anyone looking to buy a microscope knows, or quickly learns, that the total magnification of a microscope is arrived at through the simple expedient of multiplying the power of the objective lens by that of the eyepiece. So a 10x objective plus a 10x eyepiece = 100x magnification.

## What magnification is 1000x?

Objective | Diameter Of Field Of View | Magnification (10x Ocular) |
---|---|---|

4x | 4.0 mm (4.45) | 40x |

10x | 2.0 mm (1.78) | 100x |

40x | 0.4 mm (0.45) | 400x |

100x | 0.2 mm (0.178) | 1000x |

**What is the magnification of high power objective lens?**

The high-power objective lens (H) has a magnification of 40X. Draw orange stripes on the high-power objective. The body tube (C) allows the light from the objective to pass upward to form the first magnified image; that image is further magnified by the eyepiece or ocular (A). The eyepiece is usually 10X.

### What is the magnification power of 40x?

400x

The magnification power of the objective lens is used to calculate the total magnification of the compound light microscope. A 40x objective has a 400x total magnification.

### What can you see with 1000x magnification?

At 1000x magnification you will be able to see 0.180mm, or 180 microns.

**What does 3x magnification mean?**

This put simply means that any object you are attempting to focus on from 1” away would appear 10 times larger. The entire purpose as stated above is for the magnifier to deliver crisp focus and help you get a clear vision when focusing this close to the object.

#### What color is 4x magnification?

Red

Linear Magnification – In the case of the apochromatic objective in Figure 1, the linear magnification is 60x, although the manufacturers produce objectives ranging in linear magnification from 0.5x to 250x with many sizes in between….Objective Color Codes.

Magnification | Color Code |
---|---|

4x | Red |

5x | Red |

10x | Yellow |

16x | Green |

#### What is objective lens magnification?

The longest objective lens is an oil immersion objective lens, which magnifies 100x. The total magnification is 1000x if the eyepiece lens is 10x power. The oil immersion objective lens is used for examining the detail of individual cells, such as red blood cells.

**What are the functions of the objective lenses?**

The purpose of the objective lens is to gather light and enhance magnification. A typical compound microscope will have four objective lenses: one scanning lens, low-power lens, high-power lens, and an oil-immersion lens. These lenses have a magnification power of four, 10, 40 and 100, respectively.

## What is objective lens size?

Objective lens diameter is also considered a measure of the amount of light that can enter a scope. Objective lens generally range anywhere from 32mm all the way up to 75mm.

## What is a high power objective lens?

Scanning Objective Lens (4x) The scanning objective lens usually has 4x magnification and can be identified by a red strip band around the perimeter of the lens.
