Title
Zeiss Micro-spectroscope [facsimile] Abbe-Micro-spectroscopic eye-piece with wave-length scale and the 6x41/2 cm. camera attach- ment for use with the Micro-spectroscope. 4th ed.
Description
The salient features of this instrument include a comparison prism, and a mechanism for shortening the heighr of the spectrum to furnish a direct reading of the wave-length on a scale in any part of the spectrum, thus providing a means of obtaining generally applicable and comparable data
Using a labelled illustration of the instrument, each component is described in detail, in terms of its specifications, and its interaction with the whole.
The camera attachment is a necessary supplement to the Abbe micro-spectroscope, serving to record photogrammetrically any absorption and emission spectra; and for measuring the thickness of silver coatings by determining the displacements of interference bands within the spectrum.
Information on the camera attachment is presented under these headings:-
1. Uses;
2. Components of the Apparatus;
3. Directions;
4. Evaluation of wave-lengths;
A list of instruments, with their model numbers and prices concludes the document.
