The authors made an attempt to combine the characterization and one of the physical property measurements simultaneously to avoid this environment change while the measurements are made. Here, the authors presents the details of the setup fabricated indigenously to observe the textures (microscopy) and the measure of birefringence simultaneously in liquid crystals. The advantages of such an experimental setup are, a physical property can be measured (birefringence) along with the characterization of the sample, thereby reducing time spent for individual measurements, identical environment can be created for the sample for both the measurements and the manifestation of different liquid crystalline phases as well as the birefringence change at the phase interface can be visually observed which paves the way for finding out the fluctuation dominated non-linear regions (FDNLR) on both sides of the inter face.
