Publications of the Astronomical Society of the Pacific, Vol. 115, No. 804 (February 2003), pp. 235-242 (8 pages) ABSTRACT We present a design for a zero‐deviation cross‐disperser to be used with ...

Prisms are commonly used in spectroscopy for dispersing or controlling the direction or polarisation of light. This can be helpful for splitting the incoming light into its wavelength components to ...

IN studying the spectra of coloured solutions and solid substances by means of the spectrum microscope, it is most important to employ prisms having a suitable amount of dispersion. It would be a very ...

COMPOUND PRISM OF UNIFORM DISPERSION.—Messrs. C. G. Abbot and F. E. Fowle, of the Astrophysical Observatory at the Smithsonian Institution, have been investigating the possibility of obtaining a ...
