Michelson Interferometer Model Mi-03
The equipment has predefined position of components and so designed as to conduct the experiments rapidly with ease.
| Adjustable mirror: | 3cm in diameter: 0.6 cm thick; flat to l/4 wavelength on both sides; coated on one side for 80% reflectance and 20% transmission. It is mounted on a kinematic mount for adjustment in X-Y axis |
|---|---|
| Movable mirror: | 3cm in diameter: 0.6 cm thick; flat to l/4 wavelength on both sides; coated on one side for 80% reflectance and 20% transmission. The mirror travel is controlled by a micrometer having precise measurement and virtually no back lash. |
| Beam – splitter: | 50x39x7mm thick; flat to l/4 wavelength on both sides; coated on one side for 50% reflectance and 50% transmission |
| Compensator: | identical to the beam splitter, but uncoated. |
| Micrometer: | The micrometer uses a 1:20 reduction lever such that one division on the micrometer corresponds to 0.5 mm travel of mirror. The full travel of the mirror is 1.25mm. The reading through full distance of travel is linear to within 1.5%. |
The equipment has predefined position of components and so designed as to conduct the experiments rapidly with ease. With standard equipment & some additional accessories, we can find wavelength of monochromatic source, laser light & refractive index of glass.
