Abstract
The invention relates to a telescope which is used to inject and/or to extract, by reflection, emitting and/or capturing bundles of beams. According to the invention, at least one deflecting means is joined to the planar surface by means of at least one lens of the telescope objective unit, which is embodied as a plan convex or plan concave lens. The lens is used as a lens of the objective unit and as a holder for the deflection means. The number of optical components in the telescope about one of the holders is reduced due to the dual function thereof.
Claims17
A telescope for diffraction-limited imaging, comprising:
- an objective unit having at least one lens,
- a transmitting unit for transmitting a bundle of rays as bundle of transmitted rays and/or
- a receiving unit for receiving a bundle of rays as bundle of received rays,
- at least one, in particular plano-optical, deflecting means having at least one mirror surface for reflecting the bundle of transmitted rays into the optical beam path of the telescope and/or reflecting the bundle of received rays out of the optical beam path of the telescope,
- an image-erecting system,
- a focusing unit,
- optionally a sighting axis mark, and
- an eyepiece,
- wherein
- the at least one lens is in the form of a planoconvex or planoconcave lens and
- the at least one deflecting means is arranged on the plane surface of the planoconvex or planoconcave lens, lens and deflecting means being connected to one another so that they constitute a substantially integral component.
A panfocal telescope for diffraction-limited imaging, comprising:
- a first objective unit having at least one lens,
- a second objective unit having at least one lens,
- an image-erecting system,
- a focusing unit,
- an eyepiece,
- wherein
- the panfocal telescope has
- a transmitting unit for transmitting a bundle of rays as bundle of transmitted rays and/or
- a receiving unit for the receiving of a bundle of rays as bundle of received rays and
- at least one, in particular plano-optical, deflecting means having at least one mirror surface for reflecting the bundle of received rays into the optical beam path of the panfocal telescope and/or reflecting the bundle of received rays out of the optical beam path of the panfocal telescope,
- and wherein
- the at least one lens is in the form of a planoconvex or planoconcave lens and
- the at least one deflecting means is arranged on the plane surface of the planoconvex or planoconcave lens, lens and deflecting means being connected to one another so that they constitute a substantially integral component.
