• Mechanical parts are parts that serve as the framework of the apparatus.
• The draw tube in a microscope is where the eyepiece is inserted.
• The body tube in a microscope is the connection between the ocular eyepiece and objectives.
• The revolving nosepiece in a microscope is used for shifting the objectives.
• The fine adjustment knob in a microscope is used to focus the finer details of the object.
• The arm in a microscope is used for carrying the microscope.
• The inclination joint in a microscope is used to tilt the microscope.
• The pillar in a microscope is the connection between the base and the other parts.
• The base in a microscope supports the entire microscope.
• The coarse adjustment knob in a microscope is used to focus the object with the low power objective (LPO).
• The stage in a microscope is where the glass slide is placed.
• The stage clip in a microscope is used to hold the slide.
• B. ILLUMINATING OR OPTICAL PARTS - produces light entering the microscope ➢ Mirror - collects light and directs it to the object. ➢ Iris Diaphragm - regulated the amount of light in the microscope. ➢ Condenser - used to concentrate the light towards the specimen.
• Ocular Eyepiece contains lenses, magnifies objects up to 5-10x.
• Low Power Objective (LPO) is 10x.
• High Power Objective (HPO) is 40 - 50x.
• Oil Immersion Objective (OIO) is 100x.
