spectroscope

spectroscope
An instrument for resolving light from any luminous body into its spectrum, and for the analysis of the spectrum so formed. It consists of a prism that refracts the light or a grating for diffraction of the light, an arrangement for rendering the rays parallel, and a telescope that magnifies the spectrum. [spectro- + G. skopeo, to view]
- direct vision s. a s. consisting of a single tube containing a series of prisms; one end of the tube is placed in as close contact as possible with the substance to be examined while the observer's eye is at the opposite end; it can be used to make a spectroscopic examination of the blood in vivo, as in the ear lobe or web of the thumb.

n.
an instrument used to split up light or other radiation into components of different wavelengths. The simplest spectroscope uses a prism, which splits white light into the rainbow colours of the visible spectrum.
