Detailed description of the invention
Reference: 1.1 first laser instrument；1.2 second laser；2 plate glass；3 plane mirrors；4
Standard sample；5 samples；6 first ccd detectors；7 second ccd detectors.
A kind of apparatus for measuring refractive index based on standard sample, including the first laser instrument 1.1, second laser 1.2,
Plate glass 2, plane mirror 3, standard sample 4, sample the 5, first ccd detector 6 and
Two ccd detectors 7；Described first laser instrument 1.1 and second laser 1.2 send the monochromatic light of different wave length,
And the light that sends is parallel to each other；Described standard sample 4 is the cuboid that geomery is identical with sample 5
Shape；A part for the light that first and second laser instrument 1.1,1.2 sends is through passing through institute after described plate glass 2 again
Stating standard sample 4 and form the first hot spot and the second hot spot on the first ccd detector 6, another part is by institute
Reflected by plane mirror 3 again after stating plate glass 2 reflection, afterwards through plate glass 2 again through described quilt
On the second ccd detector 7, the 3rd hot spot and the 4th hot spot is formed after test sample product 5；Described plane mirror
3 is parallel with plate glass 2, light that described first and second laser instrument 1.1,1.2 sends and plate glass 2 in
45 degree of angles；Measurement apparatus also includes controller, the distance between the first hot spot and the second hot spot and the 3rd light
During distance difference between speckle and the 4th hot spot, controller judges that sample is defective.First laser instrument sends
The wavelength of light that sends more than second laser of the wavelength of light.First and second ccd detector 6,7 is face
Battle array ccd detector.The photosurface of first and second ccd detector 6,7 is parallel with described plate glass.Survey
Amount device also includes display, the distance between the first hot spot and the second hot spot and the 3rd hot spot and the 4th hot spot
Between distance difference time, controller utilizes display prompts sample defective.
Measurement apparatus of the present utility model, is placed on corresponding position by standard sample and sample, if quilt
Survey sample passes, then the distance between distance and third and fourth hot spot between first and second hot spot should be phase
Deng.If the refractive index of sample is defective, then distance between first and second hot spot and third and fourth
Distance between hot spot can be different, then show that sample is defective.
Although this utility model is illustrated with regard to preferred implementation and described, but those skilled in the art should
Work as understanding, without departing from claim limited range of the present utility model, this utility model can be entered
Row variations and modifications.
