Spectro-goniometer OPTIKA SCIENCE

Spectro-goniometer OPTIKA SCIENCE.

Instrument of excellent optical and mechanical quality, which allows precision measurements of the angles of deviation of optical rays, allowing us to determine the refractive index of solid and liquid substances as well as the wavelength of monochromatic sources.

Technical characteristics:

• Base: varnished cast iron
• Goniometer: Ø 17.5 cm and divided in 360°with an accuracy of 1°
• It is equipped with a vernier that allows to evaluate the accuracy of the measurement of 1/10°
• Telescope: equipped with an achromatic objective with a focal length of 178 mm and a 15x eyepiece
• Focusing allows fine adjustment
• Collimator: equipped with an achromatic objective with a focal length of 178 mm and an adjustable slit with continuity up to 6 mm
• Prism plane: vertically and horizontally adjustable and equipped with a clamp for fixing the diffraction grating. Diameter 80 mm
• Dimensions: 48x33x33 cm
• Weight: 12 kg

Accessories supplied:

• 1 Crown glass equilateral prism 32x32 mm
• 1 diffraction grating 500 lines /mm
• 1 magnifying lens

We recommend purchasing the 80 lines/mm and 1000 lines/mm diffraction gratings to determine the different spectral resolution of the apparatus depending on the grating used.
