Hand Spectroscope Views

• General Goods

In the original spectroscope design in the early 19th century, light entered a slit and a collimating lens transformed the light into a thin beam of parallel rays. The light then passed through a prism (in hand-held spectroscopes, usually an Amici prism) that refracted the beam into a spectrum because different wavelengths were refracted different amounts due to dispersion. This image was then viewed through a tube with a scale that was transposed upon the spectral image, enabling its direct measurement.

Hand-Held Spectroscope with Adjustable Slit Precise optical system with centred visible spectrum, which is linear with respect to the wavelength. With high-quality Amici prism in metal sleeve. Delivery in hinged case for protective and dust-free storage. Angular dispersion: C-F 7sdeg; Linear dispersion: 60 mm Slit, adjustable: 0 ... 1 mm Dimensions with case in mm: 150 x 70 x 30 Weight: approx. 150 g
