Spectrometer goniometer SG1800
For the precise determination of optical data of prisms
Krüss offers the model SG1800 Spectrometer-Goniometer, for the exact measurement of optical data on prisms. Reflection angle and deflection angle are measurable. From the measured values, for example, the inner angle of a prism or the refractive index of the material used can be determined. It can also be used as a spectroscope, for qualitative examination and measurement of emission and absorption spectra. The observation tube has combined coarse and fine drives, infinitely variable, cross-hairs, eyepiece vernier accuracy. The collimator and the telescope have a focal length of 178mm and a free aperture of 32mm. The Prism offers Flint glass (60deg) with a dispersion angle C-F=2deg. The collimator is a symmetric precision slit of hardened steel. Accessories include prism, Rowland grating and holder, scale illumination, lamp, ocular and spectra sheet.Infinitely adjustable
