HML2153 - Lesson 2.1 - Microscopy Basics

Who is credited with coining the term "microscope"?

• Hans and Zaccharias

• Galileo

• Antonie van Leeuwenhoek

• Christopher Scheiner

What type of lens is used in a simple microscope?

• Concave lens

• Plano lens

• Convex lens

• Cylindrical lens

What does the term "Neofluar" signify in microscopy?

• High chromatic aberration

• UV light transmission

• Oil immersion compatibility

• Plano field view

What property of light is most relevant for resolution?

• Amplitude

• Wavelength

• Speed

• Phase

What is the function of a microscope condenser?

• Magnify the specimen

• Focus light onto the specimen

• Adjust the tube length

• Correct chromatic aberration

What does "numerical aperture" measure?

• A) Magnification power

• B) Light-gathering ability of the lens

• C) Angle of the objective

• D) Resolution limit

Which lens type is highly corrected for chromatic aberration?

• Plan

• Apochromatic

• Dry lens

• Immersion

What is "empty magnification"?

• High magnification without increased detail

• Magnification beyond tube length

• Magnification without eyepieces

• Low numerical aperture magnification

What is the primary role of eyepieces in a microscope?

• Focusing the objective lens

• Magnifying the image from the objective

• Correcting spherical aberration

• Reducing light scatter

Which type of aberration results in specimen appearing distorted with a tail?

• Coma

• Astigmatism

• Chromatic aberration

• Spherical aberration
