Abstract
Abstract An incident light microscope permitting to view an object either from above or from below, in which the light source, the objective carrier and the elements for illuminating the object form a single unit which is turnable about an axis arranged parallel to and between a pair of support faces adapted to support an object to be viewed in the microscope and in which this axis coincides with the optical axis of part of the path of the viewing and part of the path of the illuminating rays.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
228 words
An incident light microscope comprising, in combination, support means; an upper and a lower plate carried spaced from each other by said support means and each having a substantially horizontal support face parallel to the support face of the other plate and adapted to support an object to be viewed in the microscope; ocular means; and objective carrier; at least one objective carried by said objective carrier; a light source; reflecting means for reflecting light from said light source through said objective onto an object located on one of said plates and light reflected from said object into said ocular means; housing means carrying said light source, said reflecting means and said objective carrier and forming with these elements one unit; carrier means mounted on said support means and carrying said unit turnably about a turning axis located between and parallel to said support faces, said turning axis coinciding with the optical axis of the light rays passing from said light source to said reflecting means and part of the optical axis of the light rays passing from said reflecting means to said ocular means; and means mounting said ocular means turnably about said optical axis on said housing means so that said unit including said housing means can be turned about said turning axis while said ocular means is prevented from turning together with said housing means.
Claim 2
Dependent Claim
228 words
An incident light microscope comprising, in combination, support means; an upper and a lower plate carried spaced from each other by said support means and each having a substantially horizontal support face parallel to the support face of the other plate and adapted to support an object to be viewed in the microscope; ocular means; and objective carrier; at least one objective carried by said objective carrier; a light source; reflecting means for reflecting light from said light source through said objective onto an object located on one of said plates and light reflected from said object into said ocular means; housing means carrying said light source, said reflecting means and said objective carrier and forming with these elements one unit; carrier means mounted on said support means and carrying said unit turnably about a turning axis located between and parallel to said support faces, said turning axis coinciding with the optical axis of the light rays passing from said light source to said reflecting means and part of the optical axis of the light rays passing from said reflecting means to said ocular means; and means mounting said ocular means turnably about said optical axis on said housing means so that said unit including said housing means can be turned about said turning axis while said ocular means is prevented from turning together with said housing means.
Claim 3
Dependent Claim
42 words
An incident light microscope as defined in claim 1, wherein said upper plate is fixedly mounted on said support means, and including adjusting means connected to said lower plate for moving the latter in a direction normal to said support face thereof.
Claim 4
Dependent Claim
48 words
An incident light microscope as defined in claim 2, wherein said adjusting means for said lower plate are rough adjusting means, and including fine adjusting means cooperating with said carrier means for moving the latter and said unit carried thereby in a direction normal to said support faces.
Claim 5
Dependent Claim
64 words
An incident light microscope as defined in claim 2, wherein said carrier means include an elongated member carrying said housing means turnably about said turning axis and guide means guiding said member movable in a direction normal to said support faces; and fine adjusting means mounted on said support means and cooperating with said elongated member for moving the same along said guide means.
Claim 6
Dependent Claim
46 words
An incident light microscope as defined in claim 4, and including arresting means cooperating with said housing means for selectively arresting said housing means in either of two through 180* turned positions in which the optical axis of said objective is normal to said support faces.
Claim 7
Dependent Claim
36 words
An incident light microscope as defined in claim 5, wherein said carrier means include a sleeve coaxially with and surrounding part of said housing means, said elongated member being fixed and projecting downwardly from said sleeve.
Claim 8
Dependent Claim
82 words
An incident light microscope as defined in claim 5, wherein said ocular means comprises a tubus connected at one end thereof to one end of said housing means turnably about said turning axis and projecting upwardly inclined to said axis therefrom, and an ocular mounted on the other end of the tubus and Including a stationary means connected to said support means and engaging said tubus for preventing turning of the latter during turning of said housing means about said turning axis.
