1. Field of the Invention
This invention relates to a confocal laser scanning microscope.
2. Related Background Art
A scanning optical microscope for deflecting a light beam to scan a specimen, which has acquired high resolving power but still retains convenience is known (Japanese Patent Laid-Open Publication No. 219919/1986).
This scanning optical microscope has the drawback that stray reflected and scattered light produced when the laser beam passes through the relatively large number of optical elements lowers the measuring precision of the microscope.
