The Goniometer, model no: HO-SP-RE-01 has user friendly and open design as it is explicit from the picture above. The instrument makes use of rail and carriage system for mounting various modules such as light source, adjustable slit and collimator. A precision rotation stage with coarse and fine movements holds the telescope. There are two rotation stages, concentrically assembled, one for telescope and the other for sample. All mechanical components are manufactured either in aluminum alloy or stainless steel.

The measurement of refractive index is carried out with a dispersion prism made from the material to be tested. For the measurements of fluids, a hollow prism is used which is filled with the fluid. The optical parameters like optical density, reflectivity, transitivity, absorption, polarization angle etc. are determined with the help of a photo diode detector. It can also be used as a spectroscope for qualitative examination and measurement of emission and absorption spectra. The diffraction angle of plane grating and holographic grating can also be measured. Various accessories and mounting options are available.
