Device for continuous adjustment of spectrometer gap widths

Abstract

A microscope has an aperture arrangement that, in order to limit the dimension of a light beam, comprises an aperture opening. The size of the aperture opening is adjustable with the aid of a first aperture member and a second aperture member. At least one of the two aperture members is movable relative to the other aperture member. The aperture members are spaced apart from one another when the aperture opening is closed.

What is claimed is: 
     
         1 . A microscope having an aperture arrangement that, in order to limit the dimension of a light beam, comprises an aperture opening whose size is adjustable with the aid of a first aperture member and a second aperture member, at least one of the two aperture members being movable relative to the other aperture member,
 wherein the aperture members are spaced apart from one another such that the aperture members do not get in contact with each other when the aperture opening is closed.   
     
     
         2 . The microscope according to  claim 1 , in which the two aperture members are arranged with an offset from one another in the axial direction of the light beam to be limited. 
     
     
         3 . The microscope according to  claim 1 , in which, when the aperture opening is closed, aperture edges of the aperture members are arranged with an offset from one another in the axial direction of the light beam to be limited. 
     
     
         4 . The microscope according to  claim 1 , in which one side of at least one of the aperture members comprises a reflective region that reflects a portion of the light beam, such that another portion of the light beam passes through the aperture opening. 
     
     
         5 . The microscope according to  claim 1 , in which, for adjustment of the size of the aperture opening, at least one of the aperture members is movable in a direction almost perpendicular, or perpendicular, to a beam axis of the light beam to be limited. 
     
     
         6 . The microscope according to  claim 1 , in which, for adjustment of the size of the aperture opening, at least one of the aperture members s rotatable around a rotation axis that is almost parallel, or parallel, to a beam axis of the light beam to be limited. 
     
     
         7 . The microscope according to  claim 1 , in which, for adjustment of the size of the aperture opening, at least one of the aperture members is swingable around a swing axis that is almost perpendicular, or perpendicular, to a beam axis of the light beam to be limited. 
     
     
         8 . The microscope according to  claim 1 , which comprises a spectrometer that encompasses the aperture arrangement. 
     
     
         9 . The microscope according to  claim 1 , in which the aperture arrangement is arranged in a detection beam path of the microscope. 
     
     
         10 . The microscope according to  claim 1 , in which at least one of the aperture members is embodied in circular, round, polygonal, quadrangular, rectangular, or square fashion. 
     
     
         11 . The microscope according to  claim 1 , which is embodied as a laser microscope, as a confocal microscope, as a fluorescence microscope, multiphoton microscope, and/or as a scanning microscope.
