The document describes a prism spectroscope and its uses. It can be used to analyze gemstones and other materials by separating visible light into a spectrum. When used with gemstones, it allows identification of stones such as distinguishing ruby from pink sapphire based on their absorption spectra. It works by dispersing light through a series of prisms. Proper usage, such as using reflected light at a 45 degree angle and a black background, is important for obtaining clear results. It is most suitable for analyzing materials using visible or infrared light.

- 3. R PRISM SPECTROSCOPE MODEL NO.- ACM-PS-22605 The prism spectroscope is based on dispersion. The light enters through a narrow slit (some models allow you to adjust the width of the slit) and is then dispersed through a series of prisms. Some models have an attachment with a built-in scale. These models are generally more expensive than their diffraction type cousins Because prism spectroscopes are based on dispersion, the blue area of the spectrum is more spread out and the red parts are more condensed than the diffraction grating types. Proper Usage of Spectroscope Proper use of the spectroscope and lighting is vital when wanting to see good spectra of gemstones. The most widely used technique is to make use of reflected light. Light enters the pavilion of a gemstone at a 45º angle and the spectroscope should be placed at the same angle on the other side. The light will travel its longest possible path in this way, picking up the most color. To prevent the background on which the stone lays from causing false readings, one should use a black nonreflective underground, such as a small piece of black velvet. Another technique is to position the gemstone and the light source (penlight) in one hand in such a way that the light source illuminates the gem from behind, thus viewing the gemstone in transmitted light. There are nice spectroscope stands (some with built-in illumination) on the market, but gaining some experience eliminates the need for them. For the new user, it is recommended to start with a gemstone that produces a clear absorption spectrum, such as synthetic ruby. TECHNOLOGIES PVT. LTD.
