Attachment camera

The invention relates to a microphotographic Attachment camera, in which a 35 mm camera used for normal photo purposes is used.

Usually 35 mm cameras are used in which the taking lens is removed and can be replaced by such a suitable focal length and suitable structure. In In this case, it does not cause any difficulty to switch between this camera lens and the eyepiece of the microscope is a translucent mirror or a translucent To switch on the prism cube, which is part of the light emerging from the microscope eyepiece in an adjustment telescope leads. There is also enough space to pass the prism cube through to be able to adjust suitable mechanical means so that the image seen in the setting telescope corresponds exactly to that of what is thrown on the film.

It is also part of the prior art, e.g. B. with prism binoculars the contact surface of the Train prism chair and the seat of the housing receiving it as rotating surfaces or, as was suggested in another case, adjustable by λόπ externally, on the Side surfaces of the prism acting screws the same for the purpose of side adjustment on one to move the corresponding prism holder.

However, the situation is significantly different with an adjustable prism support for a microphotographic one Mounted camera with a light-

translucent mirror or translucent prism cube that emerges from the microscope eyepiece Light partly in the normal, built-in lens of a 35mm camera and for the other part leads into an adjustment telescope. For this it is necessary for the mirror or prism cube to create an adjustment option in two different directions, namely once to Side adjustment and once for height adjustment.

ίο The use of the normal, built-in Camera lens makes it necessary to bring the lens very close to the microscope eyepiece, so that the rear lens mount of the camera lens does not affect the field of view of the microscope circumcised. This, however, creates the space between the camera lens and the microscope eyepiece very small, so that there are difficulties between the two translucent prism cube or to accommodate mirrors with the required mechanical adjustment means.

The object of the invention is to eliminate this disadvantage by means of an adjustable prism bearing, which takes up relatively little space, so that it is still between the microscope eyepiece and camera lens can be accommodated without restricting the field of view of the microscope. According to the invention is therefore the translucent mirror or the translucent prism cube attached to a carrier, which is within two cup-shaped and disk-shaped adjustment parts with these around the optical axes of the microscope and camera in one on the microscope tube centered mounted housing rotatably and additionally within its guide in the Carrier can be displaced perpendicular to the optical axis and by means of the cup-shaped and disk-shaped adjustment parts can be clamped in place. With the rotation around the optical axes, a lateral adjustment is made and by shifting it perpendicular to it, a height adjustment in the setting telescope of the Microscope attachment achieved. Lateral locking screws can be provided which one Protection against rotation of the carrier for the mirror or prism cube after adjustment enable.

An embodiment of the subject matter of the invention is shown in the drawing. It shows Fig. Ι a longitudinal section through the microphotographic attachment camera with the setting telescope,

Fig. 2 a longitudinal section through the adjustable prism bearing with the locking screws,

Fig. 3 shows a cross section through the prism cube with the prism carrier and through the telescopic sight.

The housing ι serves to accommodate the setting telescope 2, the prism carrier 3 with the adjustment parts 7 and 8 and the 35mm camera 4. The translucent prism cube 5 is housed in the prism carrier 3 between the two Cup-shaped and disk-shaped adjusting disks 7 and 8 is arranged. By fastening screws 9, the prism cube S is clamped between these two adjustment parts 7, 8. The light emerging from the microscope is transmitted through the translucent mirror surface 10 to Partly deflected into the setting telescope 2, and the other part it can be in the lens 6 of the 35mm camera 4 enter.

If the image of the microscope 11 visible in the setting telescope 2 is now laterally offset, according to the invention the adjustment part 7 rotates, as a result of which the prism cube S also experiences a rotation. This continues until the correct lateral position in the setting telescope is reached. Is that in the Telescope 2 seen image offset in height, so the prism cube 5 can be in the direction of the optical Axis of the telescope 2 are shifted slightly. It is to this shift that the screws become 9 solved something. After the correspondence between the images in the focusing telescope 2 and the camera 4 is reached, the prism mounting is held by several screws 12.

Claims (2)

PATENT CLAIMS: 1. Adjustable prism support for microphotographic Mounted camera with a translucent mirror or translucent prism cube that comes out of the microscope eyepiece some of the light escaping into the normal, permanently built-in lens of a 35mm camera and on the other hand leads into an adjusting telescope, characterized in that the translucent Prism cube (5) or the translucent mirror fixed in a carrier (3) is located within two cup-shaped and disk-shaped adjustment parts (7, 8) with these around the optical axis of microscope and camera in one on the microscope tube centered mounted housing (1) is rotatably mounted, and that the prism cube (5) or the mirror within its guidance in the carrier (3) perpendicular to the optical axis of The microscope and camera can be displaced and in their position by means of the adjustment parts (7, 8) can be clamped. 2. prism mounting according to claim 1, characterized in that the prism carrier (3) and the cup-shaped and disk-shaped ones connected to it by screws (9) Adjustment parts (7, 8) without dismantling a part after adjustment through the side Locking screws (12) can be clamped from the outside and thus secured.
