Titanium dioxide films were deposited on glass substrates by Spin Coating process. The thin film samples were characterized for its structural, optical and mechanical properties using SEM, EDAX, UV-Vis Spectrophotometer, X-ray Diffraction (XRD) and micro hardness unit. Optical constants such as k and α were studied and discussed. The variation of thickness of the thin film with number of times of deposition was found to be linear. The optical band gap energy was estimated to be 3.61 eV. Work hardening index was found to be 0.53
