Which term describes a microscope that remains in focus when the objective lenses are changed?
A
Resolving
B
Achromatic
C
Parfocal
D
Monocular
Verified step by step guidance1
Understand the concept of 'parfocal': A parfocal microscope is designed so that when you switch between objective lenses, the image remains in focus or requires only minimal adjustment.
Review the other terms provided in the question: 'Resolving' refers to the ability of a microscope to distinguish between two closely spaced objects. 'Achromatic' refers to lenses that minimize chromatic aberration (color distortion). 'Monocular' describes a microscope with a single eyepiece.
Compare the definitions: None of the other terms ('Resolving,' 'Achromatic,' 'Monocular') describe the ability of a microscope to stay in focus when switching objective lenses.
Conclude that 'Parfocal' is the correct term because it specifically refers to the feature of remaining in focus when changing magnification.
Apply this knowledge to future questions about microscope features, ensuring you understand the specific terminology used in microscopy.
