spectroscopes's Usage Examples:

This analogy is useful because the application of Fourier's analysis to the optical theory of spectroscopes has been doubted, and it may be urged in answer to the objections raised that the instrument acts in all respects like a mechanical analyser,' the applicability of which has never been called into question.

The formula expressing the optical power of prismatic spectroscopes may readily be investigated upon the principles of the wave theory.

Schumann 2 have shown, however, that with the help of spectroscopes void of air and specially prepared photographic plates, spectra can be registered as far down as lzoo A.

In grating spectroscopes both plane and concave gratings are employed in connexion with a collimator and observing telescope.

If, as in common flint-glass spectroscopes, there is only one dispersing substance, f Sy ds Sµ.

- T he modern equatorial should, for general purposes, be capable of carrying spectroscopes of considerable weight, so that the proportional strength of the axes and the rigidity of the instrument have to be considerably increased.

It follows that for observations in which light is a consideration spectroscopes should be used which give about twice the resolving power of that actually required; we may then use a slit having a width of nearly eight times that of the normal one.

The bands often appear in groups, and such spectra containing groups of bands when viewed through small spectroscopes sometimes give the appearance of the flutings of columns.

Angular prism spectroscopes are the commonest.

- Spectroscopes may be divided into two classes: prism spectroscopes, with angular or direct vision, and grating spectroscopes; the former acting by refraction (q.

In direct vision spectroscopes the refracting prisms and slit are in the observing telescope.

When spectroscopes are used for stellar purposes further considerations have to be taken account of in their construction; and these are discussed in a paper by H.
