Microscopic Gigapan of six inch ruler. The numbers mark tenths of an inch. The hash marks are hundredths of an inch.

This is a five by four image grid, with the XY stage moved manually.

This was taken with the 4x objective, through a 2.5x camera adapter. Without the camera adapter the Field of View is
4.5 mm, but with the camera adapter the Field of view is approximately 1.8 mm per picture, or 0.07"

The five images across show about 0.24", or 0.048" per picture after counting for overlap.

The image is 14,724 pixels wide, showing 0.24", or 61,350 pixels per inch, or 2,415 pixels per mm.
(please correct my math if I am wrong!)

Taken with the National Microscope model 163, which we got with generous support from Make Magazine.

This Gigapan is part of the macro/micro/nano GigaPan project, which is working to take large pictures of very small things.

This mosaic consists of 170 images taken at ~1000X magnification.
