Abstract
PURPOSE:To prevent the danger to the eyes by reflection of an incident laser beam to the inside of a spectral cell body by inclining incident window glass and exit window glass of the laser beam to the spectral cell body at a prescribed angle with the optical axis of the incident laser beam. CONSTITUTION:The incident laser beam 4a arriving at the window glass 11 through reflecting mirrors 17, 18 for beam alignment advances through the glass 11 into the spectral cell body 1. The laser beam past a slit 7 for beam alignment passes the inside of metal vapor 9 rising from a crucible 10 of an evaporation device 2 and is emitted through the exit window glass 12. The spectral analysis of the metal is executed by observing the body 1 during this time. Part of the beam 4a is reflected by the glass 11 at the time of the transmission of said beam through the glass 11. Since the glass 11 is inclined at the prescribed angle with the optical axis, this reflected beam 4b does not return onto the optical axis of the beam 4a does not return onto the optical axis of the beam 4a and is reflected downward. The beam 4B is, therefore, prevented from entering the observer's eyes and the safety is maintained at the time of observing the inside on the glass 11 side.
