Holder for optical components
View Patent ↗A holder for optical components includes a two-part holder housing that forms an essentially ring-shaped enclosure surrounding an optical component; in addition the two housing parts have different thermal expansion coefficients. To create a holder for optical components that is both simple in structure and ensures a low-tension and insulated enclosure of the optical component, it is proposed with the invention that one housing part should be configured as a ring that surrounds the optical component and on whose housing interior close to the optical component a groove should be configured that surrounds and encloses the optical component and serves as a receptacle for the second housing part, which is configured as a tension ring.
1. A holder for optical components, with a holder housing, comprising two housing parts, that forms an essentially ring-shaped enclosure surrounding an optical component, whereby the two housing parts have different thermal expansion coefficients, characterized in that one housing part is configured as a ring that surrounds the optical component and serves as receptacle for the optical component and on whose housing interior close to the optical component a groove is configured that surrounds the optical component and serves as receptacle for the second housing part, which is configured as a tension or pressure ring.
2. A holder according to claim 1 , wherein the groove is positioned in the inside of the housing of the ring-shaped housing part and sized in such a way that the groove is separated from the optical component and from a housing exterior only by a thin-walled housing stud.
3. A holder according to claim 2 , wherein the thin-walled housing stud forms a notch hinge.
4. A holder according to claim 1 , wherein the tension or pressure ring is to be pressed into the groove and is configured as a massive tension ring with a lower heat expansion coefficient than the ring that includes the groove.
5. A holder according to claim 1 , wherein the tension or pressure ring is to be pressed into the groove and is configured as a toothed pressure ring with a greater thermal expansion coefficient that the ring that includes the groove.
6. A holder according to claim 5 , wherein the toothed pressure ring is positioned in the groove in such a way that the teeth point away from the optical component.
7. A holder according to claim 1 , wherein a soldering or cementing layer is positioned as an insulating and gripping means between the optical component and the housing part that forms a ring-shaped enclosure surrounding the optical component.
