Abstract: A geodetic surveying device, wherein the geodetic surveying device is configured for surveying retroreflective cooperative targets, the geodetic surveying device comprises a base, a telescope and a support. The geodetic surveying device further comprises a target recognition emitting unit, called ATR-illuminator, an target recognition sensor, called ATR-sensor, having a position-sensitive area for receiving radiation of the radiation beam reflected at the retroreflective cooperative targets for generating ATR image data, wherein the received radiation appear as spots in the ATR image data, an angle encoder and a processing unit. The geodetic surveying device generates a series of ATR image data with continuously changing orientation of the ATR-illuminator and/or the ATR-sensor.

Abstract: The invention relates to a subassembly (1) for an objective (10), in particular for a long and slim optical image transmission system, for example an endoscope, an objective (10) and an optical image transmission system, as well as methods for manufacturing a subassembly and an objective. The subassembly (1) comprises a prism (2) and an aperture element (3), wherein the prism (2) and the aperture element (3) are fixedly connected to each other, preferably by means of a putty or via direct bonding.

Abstract: An apparatus (100) for collimating a light ray field (1), a diode laser, the use of a collimation lens system (1), a collimation method and a method of producing a collimation apparatus. The apparatus (100) collimates a light ray field (L), which diverges more quickly in a first direction (F), perpendicular to the emission direction(s), than in a second direction (S), perpendicular to both the emission direction(s) and the first direction (F). The apparatus (100) comprises at least one first collimation lens system (1) for collimating the light ray field (L) in the first direction and at least one second collimation lens system (2) for collimating the light ray field in the second direction. The first collimation lens system (1) comprises a glass cylindrical lens (3) with an at least partly circular profile (4). The first collimation lens system (1) comprises an aspherical plastic lens element (5).
