Unidirectional <001> Pure and NaCl-doped triglycine sulfate (TGS) crystals were grown by Sankaranarayanan–Ramasamy (SR) method. The grown crystals were then studied by atomic absorbtion, optical transmission and Fourier Transform Infrared (FTIR) spectroscopy techniques, microhardness and surface etching techniques. The NaCl-doped TGS crystal showed higher transmission than the pure crystal in the entire UV-Vis. region. It was observed that the NaCl additive caused the growth rate of TGS crystal in the  direction to increase.
