PPT-1 Optical Mineralogy Lab 13 – Fall

2017 Uniaxial Interference Figures 2 Conoscopic Observation In order to observe an interference figure the microscope must be used in the conoscopic mode Conoscopic refers to the coneshaped illumination obtained when the condenser lens is near the thin section.
