Abstract	topographic properties of the surface thin films which are prepared by reflective optical microscope. As a consequence, the optical parameters of the films were determined by using spectrometer type (SHEMATZU), The optical properties were studied for range of wave length (3001100nm).Transmission were (89%-83%), this ratio is depended on thickness and doping ratio of the films, where as transmission proportion reversely with increasing doping .The absorption coefficient is determined and correlated with the photon energy in order to estimate the direct transition energy band gap. Direct band gap values of 2.1 -2.6 eV were obtained.The refractive index and Extinction coefficient is reported on depending on the ratio of doping and was obtained from transmission spectra.From this reason ,the films doping can be useful to prepare CdS photovoltaic (solar cells). :ةصلاخلا ي(ر ري يةةيق ةيشغأ ترضح ، ثحبلا اذه يف CdS ) بيطنل ش يحنل ل ب يششلاا ييةنلا (2%,4%) ي يةشةملا ظريلا يةيرطل ييق دشل ييقدي ولاا يدة ا يملا ييقد ( يةل ح ري ح ينسلا ري يػادي وي ػ يضق يشغلا اذه. يقارحلا (0.05) قاريح ينق لا (300 0 C) طلا ةفارغدبط ضحف مت . ي أ ، ةن ة ظتنأ ك شت هنأ رهظا ص( ؼلا ي دضلا رهجشلا ط ضدل رضحشلا ةشغلأل حط عدن ف ةطشلا يا ختضأل يذ فنلا فةط ضاقا للاخ ر تصخش ةف يرصبلا صادخ ل بطنل ل (SHEMATZU) يةند لادطلأا تيحاارت (300-1100)nm ا يحل ا ين يةل ػ ييذ فن كي تشت ةيشغلأا غأ رةيبت ثيةح ، ا (89%-83%) كشيطلا غ ي( ثيةح (900 nm) يشةي رةةؼت مت كلذ( ، ) ةطششلا يلاخلا ظ بنلا غةنصت يف يا ختضلأل ه هؤي ش هتيذ فن غ صةن ولا تاأ ي ل شلأا ة شػ غأا ر ل ش ا بطن ا يز غ ضي نتت هنا عحدلا يرصبلا ي طلا دجف 2.6 eV ويلا) 2.1 eV ولا ب يطح ميت اريةخأ .) يريصبلا تيلاد رةيطحت ويلا تاأ يي ل يش ا غا ينؼي ش ل ش ا بطن ا يز غ يارط ض نتت هنأ رهظا )ادشخلا ،ق طمن ا ، ص صت ا ؼ شغلا اذه صادخ .
