Abstract

The image of the microscopic object visible in the eyepiece is superimposed on the image of a surface of the drawing located next to the microscope. The aim of the invention is to provide a drawing device that is easily adjustable to different viewing angles. According to the invention, this is achieved by pivotally supporting the extension arm of the drawing device in its coupling point on the microscope, and with the head of the extension arm being rotatable about the axis of symmetry of the delivery arm with a first reflection system.

Application field of the invention

The invention relates to a drawing device for binocular microscopes according to WPi 149 429 ". By the drawing device, the reduced image of the drawing surface is the image dos microscopic object in an intermediate image plane heights» and superimposed in the correct page. Such devices generally consist of a reflection system for elevation and image reproduction of the drawing surface, a projection system composed of projective and transport optics for the drawing surface beam path, image shifting optics for the micrometer beam path and a beam splitter for superimposing both optical paths Drawing device are arranged in a Auslegearm, which is attached with his foot to the microscope and with his head over the drawing surface.

In the solution described in the main patent, an intermediate piece is attached between an angle tube, which contains a deflection system that generates the glare, and the binocular tube of the microscope. The intermediate piece contains a beam splitter prism and image shifting optics. An extension arm can be connected to the intermediate piece, located either on the left or on the right side of the microscope.

The use of the drawing device for microscopes with different insight inclination or working with different

Mesa of the drawing area is only possible by an exchange of the intermediate piece and by reorientation of the surface normal of the Strahlentailerprismas «On the intermediate piece must be changed to the angle between the approach surfaces and the beam splitter, the orientation of the surface normal within the plane of symmetry of the microscope»

Aim of the invention;

The aim of the invention is to provide a drawing device ^ which is easily adjustable to different viewing angles on the microscope or inclinations of the drawing surface and thus allows a quick approach to different microscopes »

Explanation of the nature of the invention

The invention is based on the object ^ to improve the drawing device according to the main patent ^ that can be compensated without changing the spacer by simply setting a change in the inclination or inclination of the drawing area »According to the invention the object is achieved in that the extension arm in its Ankoppelstelle is mounted arbitrarily pivot about the optical axis of its emerging in the direction of the intermediate piece beam on the intermediate piece · by locating the head of the boom · »Liehe input-side portion of the reflection system is emerging around the optical axis ₁ SeInSs beam which coincides with the symmetry axis of the outrigger arms, rotating * * Bar * The extension arm can be advantageously coupled to the intermediate piece either from below or from above «. When coupling from below, the reflection system in the extension arm realizes an odd number of reflections, and when coupled from above, the reflection system in the extension arm realizes an even number of reflections »

In a change in the viewing angle or »a change in the inclination of the drawing surface of the head of the extension arm is rotated so that the main section of the input side reflection system is parallel to the drawing surface« appears the image of the drawing surface twisted in the eyepiece, this is done by pivoting the boom in his Ankoppelstelle balanced on the intermediate piece. 3802

The invention will be explained in more detail with reference to the schematic drawing "Ea show en Fig" 1; a drawing device according to the invention, wherein the extension arm attached to the intermediate piece from below

FIG. 2 is a drawing device ₉ according to the invention, with the extension arm being placed on the intermediate piece. FIG.

In both figures, the extension arm is shown rotated by 90 °.

FIG. 1 shows a drawing device consisting of an intermediate piece 5 and a delivery arm 6, wherein the delivery arm 6 is coupled with its foot 12 from below to the intermediate piece 5 and its head 7 lies above the drawing surface 19. The intermediate piece 5 is located between an angle tube 3 and a binocular tube 4 "The angle tube is placed on a tube support 2 of a microscope 1" In the intermediate piece 5 an image transmission optics 16 for the microscope beam gear 27 and a Einspiegelprisma 17 are arranged with a beam splitter surface 18. The extension arm 6 contains in the head. 7 a deflecting prism 8 with a roof edge 9 and in the foot 12 a deflecting prism 13 »Both deflecting prisms 8, 13 are each designed as a half cube prism« the total number of in the extension arm 6 ·. effective reflection surfaces is odd. In addition to a projective 10, a transport optics 11 is installed in the extension arm 2 »between the extension arm 6 and the intermediate piece! 5 is a coupling point exists · The coupling point consists of a lug element 28 at the foot 12 of the extension arm 6 and a receptacle 29 on the intermediate piece 5 «The deflecting prism 8 in the head 7 of the extension arm 6 is in a circular cylindrical sleeve 30 having a corresponding opening 31 for the Drawing-surface-beam 20 has, arranged «

The embodiment in FIG. 2 differs from FIG. 1 essentially in that the extension arm 6 is coupled with its foot 12 on the intermediate piece 5. The effective reflection coefficient for the articular surface 20 - 3802

within the boom 2 is straight. The deflection prisms 8 and 13 in the extension arm 6 are designed as half-cube prisms. A projective 26 is a short focal length system with a negative focal length.

The operation of the embodiments is that the coming of the drawing surface 19 Art surface beam 20 is reflected by the deflecting prism 8 in the head 7 of the extension arm 6 in the extension arm 6 The projectile 10, 26 generates an intermediate image, which then by the transport optics 11 on the Einspiegelprisma 17 is shown in the Okularzwischenbildebene the binocular tube 4 real. In this case, the drawing surface beam is superimposed by the beam splitter 18 to the microscope beam path 27. The different angles of inclination or inclinations of the drawing surface 19 are corrected as follows:

First, the deflection prism 8 is rotated in the head 7 of the extension arm 6 by means of the sleeve 30 about the optical axis of the reflected beam, so that the plane of the "opening 31 and thus the entrance surface of the prism 8 is aligned parallel to the drawing surface 19. Das Image rotation of the drawing surface 19 is then canceled by pivoting the extension arm 6 about the optical axis within the attachment element 28. In this case, a slight inclination occurs between the drawing surface 19 and the plane of the opening 31. This occurs in the case of a drawing device which, for example, has an inclination to incline 20 °, less than 1 °, so that with an example designed for 25 ° drawing device which occur in microscopic praxis insights are easily compensated.
