Description

DETAILED DESCRIPTION OF THE INVENTION Background of the Invention The present invention relates to a drawing device or macro (
macroscopic tissue) related to photographic accessories. It relates in particular to an imaging device for use in a microscope, or to a macrophotographic accessory, which has a deflection device for deflecting a downwardly directed microscope object beam laterally and upwardly into an eyepiece for image observation.

Drawing devices or macrophotographic accessories for use with upright microscopes are known. In devices of this kind, the light is directed upwards from a horizontal plane, which has a drawing surface or a horizontally arranged macroscopic object, ie a macroscopic object. The luminous flux, or beam, is laterally deflected by a first deflection device having a single reflective surface and is deflected upwardly by a semi-transparent surface that reflects the image to the upper eyepiece, which surface is connected to the microscope objective and the eyepiece. placed between.

These reflections are canceled since the surface that reflects the image is parallel to the reflective surface of the first deflection device. Although an intermediate image is formed on the optical path between the horizontal surface and the reflective surface, no intermediate image exists within the microscope except for the image formed on the eyepiece surface. Therefore, the image on the drawing surface appears as an upright image, and also appears in the eyepiece as an image that is not laterally reversed, so drawing on a horizontal surface is facilitated.

The above device cannot be used with an inverted microscope.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a drawing device or a close-up attachment device that can be used in an inverted microscope. The present invention provides a drawing device or an accessory device for macro photography used in a microscope, which is equipped with a deflection device that deflects the image to the eyepiece and reflects the image, and a surface that reflects the image is provided between the microscope objective lens and the deflection device. the reflective surface reflects the drawing surface or macro-object into the microscopic object beam by a first deflection device, the first deflection device t directing an upward direction from the horizontal drawing surface or from the horizontally disposed macro-object. a second deflection device for deflecting the beam laterally and in a plane parallel to the plane in which the microscopic object beam is deflected, and for deflecting the beam deflected by the first deflection device downward;
and the beam deflected by the second deflection device to the first
and a third deflection device that deflects the beam at right angles to the beam between the second deflection device and toward the image plane, one of these three deflection devices having two reflecting surfaces that produce image reversal. and the other two (5) deflectors each have one or an odd number of reflective surfaces, such that one intermediate image of the macro object or drawing surface is located between the drawing surface or macro object and the image projection surface. The image reflecting surface, the first and second deflection devices, and the observation surface are formed between the image reflecting surface,
The third deflection device and the second deflection device are configured to be located on the same side with respect to a plane including the second deflection device. As described above.

The image of the drawing surface or macroscopic object is reproduced in the viewing eyepiece of the microscope in an upright and laterally uninverted state.

The deflection device for reversing the image is preferably a pentagonal prism with two reflective surfaces.

In addition, any deflection device having an image projection surface other than the deflection device for observing an image is preferably one that deflects the beam by 90°.

In a particular embodiment of the invention, an intermediate image of the microscopic object is formed between the viewing surface and the microscope objective and is transmitted to the two reflective surfaces of the third deflection device to invert the image; In the case of an inverted microscope, no intermediate image 6z is formed between the observation surface and the microscope objective, and it is necessary to invert the image using two reflective surfaces of the first or second deflection device.

DESCRIPTION OF THE PREFERRED EMBODIMENT The drawings showing preferred embodiments of the present invention will be described below.

In the accompanying drawings, the drawing surface is indicated by the reference numeral 10; the macro object (large object visible to the naked eye) beam emanating upward from this drawing surface is indicated by the reference numeral 12. This beam 12 is directed to a first deflection device 1 having one opaque reflective surface.
4 and passes through a lens 16 and impinges on a second deflection device 18 having one opaque reflective surface, where the object beam 12 is again deflected by 90° in a downward direction. The reflective surfaces of deflection devices 14 and 18 are both arranged at right angles to the optical path plane of the beam. The lens 16 is connected to the drawing surface 10. If necessary, an intermediate image 20 of the macroscopic object is also formed between the second deflection device 18 and the third deflection device 22.

The third deflection device 22 has two reflective surfaces 24 that cause image reversal.
and 26, this prism is arranged as shown and the beam is deflected downward in the second deflection device [18, in a plane perpendicular to the optical path plane from the drawing surface 10 to the third deflection device [18]. is deflected by 90°. Macro object beam 12 reflected by pentagonal prism 22 passes through lens 28;
The image is reflected upon impingement on a semi-transparent, semi-reflective surface 30 which is arranged perpendicular to the beam path plane between the second deflection device 18 and the lens 28 and directs the macro object beam away from the microscopic object 32. Reflected into the downward microscopic object beam.

The microscope objective is designated by the reference numeral 36.

A semi-transparent mirror for illumination is also indicated at 38. The microscope object beam 34 and the macro object beam 12 deflected by 90° at the image reflection surface 30 pass through a deflection device 4°, and their images are observed. In the illustrated embodiment, this deflection device is a semi-transparent mirror. The beam then impinges on film plane 42.

A portion of each of the microscopic object beam 34 and the macroscopic object beam 12 is deflected by a semi-transparent mirror 40, these deflected beams being parallel to the optical path plane between the drawing surface 10 and the third deflection device 22, and Second deflection device 18 and image reflecting surface or deflection device 40
is directed obliquely upward in a plane that is on the same side as the optical path plane of the macro object beam between. In other words, the apparatus shown in FIG. 2 is exactly the same as in FIG. The beam deviates from the plane of the paper.

Lens 28 produces an intermediate image of the macroscopic object at position 42, at which position the microscope objective also produces an intermediate image of the microscopic object. Another lens 44 forms an image of the film surface 42 on an observation surface of an eyepiece 46 (not shown).

It is clear that the macro object or drawing surface is rotated 3 times by 180° by the lenses 16.28 and 44, so that the image of the drawing surface or macro object is 18 degrees in the eyepiece.
Appears rotated by 0°. This rotation must be compensated for, and this compensation is accomplished by the deflection device [14, 18, 22
, 30 and (9) and 40.

The deflection device 40 may also have three reflective surfaces, but these reflective surfaces need only have the same effect as a single reflective surface. The deflection devices 14 and 18 are also two or more 9
For example, it may have three or five reflective surfaces as long as the same result can be obtained. Similarly, there are two deflection devices [22].

It may have four or six reflective surfaces.

However, it is generally better to avoid unnecessarily complex designs.

If the formation of intermediate images 4a of the microscopic and macroscopic objects is omitted, the deflection device 22 can be replaced by one of the deflection devices 14 and 18.

Deflection devices 14, 18, 22 and 3o are mounted on the side of the microscope in mirror image relation, depending on whether the user is right-handed or left-handed, and in both cases are placed upright above the drawing surface. Moreover, an image that is not laterally reversed can be obtained in the observation eyepiece.

Further, the image-reflecting surface 3o may be made opaque or movable. By rotating this surface 30 by 90 degrees and making it semi-transparent and semi-reflective, the image of the object will appear on the drawing surface 10. In this case, the device can be used as a drawing accessory.
