We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.

Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

STERE0PT1C0N TROUBLES 123 STEREOPTICON TROUBLES Noticeable on the Screen 1. Stereopticon Picture Smudgy-Looking (a) — There may be some oil or dirt on the slides. Clean the slides very carefully. (b) — Perhaps there is some oil or dirt on the optical system. This should be examined and then cleaned and polished. (c) — Not properly focused. 2. "Ghost" in Center of Stereopticon Picture (a) — In this case the condenser and the arc may not be in proper relation to each other, and therefore the space between them should be either increased or decreased. (b) — The optical train may not be correctly aligned — that is, the elements may be either out of adjustment with one another, too close together, or too far apart. It is, therefore, necessary to readjust them.
