These spectroscopes are designed for quick and reliable observations are designed for different kinds of spectra and are suitable for physicists, signal engineers and laboratory technicians, when it is not required to make definite measurements. The slit is constructed in a most careful manner and accurately adjustable. Dispersion is accomplished by a series of three prisms. An achromatic lens is situated between the dispersing prisms and the slit. The slit is brought into focus by the axial displacement of the lens. Both spectroscopes Nos. 3156 and 3157 are identical except that No. 3157 is provided with a. comparison prism, rendering a standard spectrum, and clamp for holding specimen vials, containing the fluid under examination.
