Use of Microscopes

It is the larger pair of knobs that move the body tube.

• Fine adjustment knob

• Coarse adjustment knob

• Revolving nose piece

• Objectives

In what objective do the smaller knobs is commonly used?

• Scanner

• Low Power Objective

• High Power Objective

Given a magnification of 10X (ocular lens) and 40X (objective lens), compute for the theoretical magnification.

• 4X

• 400x

• 50X

• 40X

To focus a specimen, it is best to start with which objective:

• Scanner

• Low power

• High power

It regulates the amount of light reaching the specimen

• Mirror

• Objectives

• Diaphragm

• Adjustment knobs

Supports the microscope and located at the bottom.

• Base

• Arm

• Body tube

• Stage

Type of objective with 10X magnification

• Scanner

• Low Power Objective

• High Power Objective

All are illuminating parts of microscopes EXCEPT:

• Mirror

• Condenser

• Diaphragm

• Objectives

This part of the microscope allows it to be tilted.

• Inclination Joint

• Arm

• Base

What is the theoretical magnification of scanner?

• 40X

• 100X

• 400X

• 1000X
