<P>PROBLEM TO BE SOLVED: To provide a space optical transmission device which is constituted simply and assembled and aligned simply, and in which an attenuation is reduced; and to provide an optical transmission device used for the space optical transmission device. <P>SOLUTION: The space optical transmission device has an optical transmitter 5 with a 2-wavelength laser 10 emitting a visible light and an infrared light in which the optical-axis interval of oscillation lights is arranged adjacently in 1 cm or less, and a transmission lens system 21 mounted on an optical axis in the transmission direction in front of the laser 10, and an optical receiver 7 being installed on the optical axis in the transmission direction while being opposed to the optical transmitter 5 and having a photodetector 25 with a sensibility in at least the infrared light. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
