Indium sulphide (InS) thin films have been synthesized by spray pyrolysis technique at 300°C temperature by spraying aqueous solutions of InCl3 and thio urea. Thickness of as deposited thin films were measured by weighing method and found in the range of 0.4840 µm, 0.4734µm and 0.4578 µm. Indium sulphide has recently attracted much attention due to its potential in optical sensors as photo conducting material and in photovoltaic applications as a wide gap material. The optical measurement showed films had a maximum transmittance of 68 % in the visible region. Energy band gap varied in the range 2.54 eV, 2.42 eV and 2.34 eV .The optical parameters of the films have been determined using conventional transmission and reflection spectra. The optical study that included the absorption and transmission spectra in the spectrum wavelength ranges 380-998 nm demonstrated that the value of absorption coefficient was 10 -5m-1.
