| Abstract: | A binary optical element which is designed to convert a single mode He Ne laser beam into a ring shaped intensity distribution is investigated experimentally. The measured diffraction efficiency are compared with numerical calculation when the distance between BOE and the output plane is changed. |

| Keywords: | binary optical element (BOE) beam shaping diffraction efficiency |
