dc.description.abstractOptical components are found in everyday life like mirrors and lenses.For different types of measurement and research optical components characteristics of are very vital, quality of mirror such as surface quality and flatness are very important. In this research there are two systems were built to analyze the correlation between fringes and the quality of the mirrors, using the method of direct contact and Michelson interferometer method. The direct contact method was constructed using a white LED, an optical flat as the reference mirror, and 3 MP CMOS camera. The Michelson interferometer method was constructed using a diode laser source with the wavelength of 650 nm,where one of it’s mirror was an optical flat as a reference. The samples used were 3 mirrors with a 1/10 ⋋ precision, 4 mirrors with a 5 ⋋precision, and 2 mirrors with 4-6⋋ precison. The fringes were recorded with CMOS camera and the data was then processed using image processing software by measuring the fringe distance in the form of Pixel. The mirror with 1/10 ⋋ precision shows that the amount of fringes are greater and straighter with the average fringe amount of 8 fringes, the fringes from the mirror with the precision 5 ⋋the average fringes amount are 5 fringes and the total average fringes with precisionof 4-6 ⋋ are 7 fringes. The results showed that at contact method, 1/10⋋ mirrors had lesser fringi number than 5⋋ mirrors i.e 4 and 5 respectively and under fringe distancethan 5⋋mirrors which were 120 pixel and 161,3 pixel. The result showed for interferometer method, the fringe numbers were for 1/10 ⋋ than for 5⋋,and 4-6⋋ which were7,5, and 6 respectively while the fringe distances were smaller for 1/10⋋ mirror than 5⋋and 4-6⋋ mirroren_US
