An optical spectrometer uses Dispersive Prisms to split the lightwave into the different colours(wavelengths). As the light passes through the dispersive prism, the ...
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 ...
MR. C. D. AHRENS, the veteran prism-cutter, has lately devised a new type of liquid prism, which seems to have some advantages in optical work, both for direct-vision and for ordinary patterns of ...
