Description
Die Erfindung bezieht sich auf einen Reellbildsucher mit zumindest einer Kittlinse, die aus zwei Linsenelementen besteht.The invention relates to a real viewfinder at least one putty lens that consists of two lens elements consists.
Wenn diese Linsenelemente zu einer Kittlinse verklebt werden, so drückt sich manchmal Klebstoff teilweise aus dem Bereich der Klebefläche seitlich heraus. Dies kann zur Folge haben, daß die Kittlinse nicht auf geeignete Weise in einen Linsenrahmen eingebracht werden kann. Wenn man aber den herausgequetschten Klebstoff durch ein Lösungsmittel beseitigt, so kann dies zu einer Beschädigung der Linsenelemente führen, insbesondere wenn diese aus Kunststoff bestehen. Das Lösungsmittel kann nämlich das Linsenelement anlösen und dadurch trüb bzw. opak machen.When these lens elements are glued to a putty lens glue is sometimes pressed out of the Area of the adhesive surface from the side. This can lead to Consequence that the putty lens is not suitable in a lens frame can be inserted. But if you the squeezed out adhesive with a solvent eliminated, this can damage the Perform lens elements, especially when they are out Plastic. The solvent can do that Loosen the lens element and make it cloudy or opaque.
Es ist daher Aufgabe der Erfindung, einen Reellbildsucher der eingangs genannten Art zu schaffen, bei dem die Kittlinse so hergestellt ist, daß sie ohne Beschädigung der Linsenelemente auf einwandfreie Weise in einen Linsenrahmen eingesetzt werden kann.It is therefore an object of the invention to provide a real view finder to create the type mentioned, in which the Putty lens is made so that it is without damage to the Lens elements in a flawless manner in a lens frame can be used.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in zumindest einem der Linsenelemente eine Klebstoffaufnahmeeinrichtung und insbesondere ein Klebstoffaufnahmehohlraum ausgebildet ist. This object is achieved in that in at least one of the lens elements Adhesive receiving device and in particular a Adhesive receiving cavity is formed.
Durch das Vorsehen des Hohlraumes besteht die Möglichkeit, den herausgequetschte Klebstoff von diesem Hohlraum aufnehmen zu lassen. Dadurch befindet dieser sich also im Innern eines für die optischen Zwecke nicht eingesetzten Teils der Linse befindet. Daher kann der Rahmen auf einwandfreie Weise ohne die Notwendigkeit der Beseitigung des herausgequetschten Klebstoffes aufgesetzt werden.By providing the cavity, it is possible the squeezed out glue from this cavity to be recorded. This means that it is in the Inside one not used for optical purposes Part of the lens is located. Therefore the frame can be on flawless manner without the need for elimination of the squeezed out adhesive.
Insbesondere wenn eines der Linsenelemente einen größeren Durchmesser hat als das andere Linsenelement und der Rahmen in dem Bereich angesetzt wird, welcher bei dem Linsenelement größeren Durchmessers radial nach außen vorsteht, wird der Klebstoff sicher von dem Hohlraum aufgenommen, wenn sich dieser im überragenden Abschnitt des Linsenelementes größeren Durchmessers befindet, und zwar im Randbereich der Klebefläche und in der Fläche des mit dem größeren Durchmesser versehenen Linsenelementes, welche mehr oder weniger eine radiale Verlängerung der Klebefläche darstellt, d. h. also auf das Linsenelement mit kleinerem Durchmesser gerichtet ist.Especially if one of the lens elements has a larger one Has diameter than the other lens element and the frame is applied in the area, which in the Larger diameter lens element radially outward protrudes, the adhesive is securely removed from the cavity recorded if this is in the outstanding section of the Lens element of larger diameter is located in Edge area of the adhesive surface and in the area of the with the larger diameter provided lens element, which more or less a radial extension of the adhesive surface represents, d. H. So on the lens element with a smaller one Diameter is directed.
Die Erfindung wird nachfolgend anhand eines in den Zeichnungen rein schematisch dargestellten Ausführungsbeispieles näher erläutert. Es zeigt:The invention is described in the following in the Drawings shown purely schematically Embodiment explained in more detail. It shows:
Fig. 1 die Linsenelemente einer Kittlinse vor dem Verkleben, und Fig. 1, the lens elements of a putty lens before gluing, and
Fig. 2 eine verklebte Kittlinse mit der Darstellung des herausgequetschten Klebstoffes sowie dem angesetzten Linsenrahmen. Fig. 2 is a glued cement lens with the representation of the squeezed out adhesive and the attached lens frame.
Die in Fig. 1 und 2 dargestellte Kittlinse besteht aus Linsenelementen 100 und 200, wobei das Linsenelement 100 einen größeren Durchmesser hat als das Linsenelement 200. In dem radial über die Kittfläche und im zusammengeklebten Zustand der Linse über das Linsenelement 200 radial vorstehenden Abschnitt 110 des Linsenelementes 100 befindet sich ein Klebstoffaufnahmehohlraum 111.The cemented lens shown in FIGS . 1 and 2 consists of lens elements 100 and 200 , the lens element 100 having a larger diameter than the lens element 200 . An adhesive receiving cavity 111 is located in the section 110 of the lens element 100 which projects radially beyond the cemented surface and in the glued-together state of the lens via the lens element 200 .
Wenn die beiden Linsenelemente 100 und 200 mit ihrer konkaven bzw. konvexen Fläche optisch ausgerichtet miteinander in Verbindung und durch Zwischenschaltung eines Klebstoffes 300 miteinander verklebt werden, so quetscht sich häufig überschüssiger Klebstoff radial heraus. Dieser Klebstoff muß erfindungsgemäß nicht entfernt werden, da er in den Hohlraum 111 eindringen kann und somit das Ansetzen eines Linsenrahmens 400 nicht behindern kann. Somit ist es nicht notwendig, die Klebstoffmenge exakt so genau einzustellen, daß kein Klebstoff herausgequetscht werden kann, was möglicherweise bei zuwenig Klebstoff zu einer ungenauen Klebung führen würde. Somit ist die Herstellung der Kittlinse wesentlich vereinfacht.If the two lens elements 100 and 200 with their concave or convex surface are optically aligned with one another and bonded to one another by interposing an adhesive 300 , excess adhesive frequently squeezes out radially. According to the invention, this adhesive does not have to be removed, since it can penetrate into the cavity 111 and thus cannot hinder the attachment of a lens frame 400 . It is therefore not necessary to adjust the amount of adhesive precisely enough so that no adhesive can be squeezed out, which would possibly lead to inaccurate bonding if the adhesive was insufficient. The manufacture of the putty lens is thus considerably simplified.
Der Klebstoff muß auch nicht unbedingt von Haus aus in den Hohlraum eindringen. Wenn der Rahmen gemäß Fig. 2 an den überstehenden Rand des Linsenelementes 100 größeren Durchmessers angesetzt wird, so kann dabei der überschüssige Klebstoff automatisch in den Hohlraum 111 verdrängt werden, wie dies der Fig. 2 deutlich zu entnehmen ist.The adhesive does not necessarily have to penetrate the cavity from the inside. If the frame according to FIG. 2 is attached to the protruding edge of the larger diameter lens element 100 , the excess adhesive can be automatically displaced into the cavity 111 , as can be clearly seen in FIG. 2.
