The objective is to present conception of creation a spectrophotometer used by students during different competitions to test a soil samples collected by Mars rover. In the first paragraph, there is information about the application of spectrophotometry and about the aim of this work. In the second paragraph includes a description of basics information about the spectrophotometer and its principle of operation. The third paragraph described elements of electronics and wiring, mechanical part needed to correct action and measurements values. This paper also describes necessary steps in measurement method and requirements that device must fulfil. In order to verify the operation of the device, it will be compared with the operation of a specialized spectrophotometer which is written in the paragraph called “Requirement”.
