| Popis: | A shrink fitter is a ring-shaped new machine element to join mechanical components with different coefficients of thermal expansion. As an application of the shrink fitter several optical lenses were shrink-fitted in a lens-barrel using the shrink fitter. The optical axes of the several lenses in the lens-barrel agreed with each other regardless of changes in room temperature. The scanning lens assembled by the shrink fitter could focus the laser light well even over a wide scanning width. If such a scanning lens was incorporated into a laser microscope, object surfaces could be observed over a wider area, compared with the conventional microscope. In this study we have developed a new type of laser microscope with a field of view of 10 by 8 mm. The pixel number in the laser scanning direction of 10 mm was 20,000 and 16,000 in the perpendicular direction of 8 mm. Thus, one field of view of this laser microscope has 320,000,000 pixels. The observation result of some surfaces by this laser microscope are reported. |
