Specific embodiment
Invention thought of the present utility model is:Using reequiping to the object stage in spectrometer so as to which area expands, and Beam-splitting board, compensating plate, flexible mirror and stationary mirror are installed, and becomes Michelson interference experimental provision.
This utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 2 to 3, a kind of Michelson interference experimental provision, including:Telescope 2, object stage 3, collimator 1; And the reading disk 4 and base 5 of the lower section of object stage 3;Object stage 3 and reading disk 4 are by rotating shaft 11 and the phase of the base 5 Even, telescope 2 and collimator 1 are connected respectively with rotating shaft 11, and can in the horizontal plane rotate around the rotating shaft 11;Rotating shaft 11 it is upper Portion is provided with locking jackscrew 6, and for fixed or release the pole 9 for replacing the bottom of platform 7 is arranged on.
Object stage 3 includes:Drag platform 10 and replacement platform 7;Wherein, drag platform 10 is arranged on the top of the rotating shaft 11, the drag platform 10 center is provided with groove 8;Replace the lower end of platform 7 to be arranged in the groove 8;The upper end of replacement platform 7 is provided with area and is more than The table top 12 of object stage 3;The bottom for replacing platform 7 is provided with pole 9, for being inserted in the groove 8;Replace the upper end of platform 7 Table top 12 is disc-shape.Pole 9 is cylindrical shape.
