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

  • With crosshair eyepiece and vernier reading accuracy of 1angular minute
  • Flint glass prism
  • High-quality collimator made of hardened steel with symmetrical precision gap
  • Extensive accessories
Applications

Typical applications

  • For angle measurement on optical components
  • Determination of reflection angle and deflection angle
  • Determination of the inside angle of a prism
  • Determination of the refractive index of the material used
