Microscope and Microscopy

Zaccharias Janssen and Hans Janssen created a magnifying device that served as the forerunner of the compound microscope and the telescope.

Who coined the term "cell"?

What results in misalignments and other distortions between different channels in a microscope image which reduces spherical aberration?

What is a condition that must be fulfilled by a lens or other optical system in order for it to produce sharp images of off-axis as well as on-axis objects?

What kind of microscope, developed by Zsigmondy, can study objects below the wavelength of light?

Who developed the phase-contrast microscope?

What type of microscope is commonly used and can show images in two dimensions?

What microscope uses electron illumination and can show images in three dimensions?

If the ocular lens' magnification if 10x, and you observing a specimen using LPO, what is the total magnification?

What part of the microscope controls the amount of light going through the specimen?

What is used to fine focus the image when viewing at the higher magnifications?

When carrying a microscope, you must must use both hands -- one holding the arm, the other supporting the base.

Optical surfaces must be cleaned in a zig-zag pattern.

When changing objectives, use the revolving nosepiece.
