In a method for registering measurement points on a body, in particular on an eye, measurement points are registered along a trajectory on a surface of the body, in particular a curved surface of the body, for determining an axial length profile, by way of a measurement beam. Here, a minimum radius of curvature of the trajectory is at least 1/7, preferably at least &#x2155;, particularly preferably at least &#x2153; of a radius of a circumference of the surface.

Measuring method

An adapter () for an apparatus () for measuring a first property of an eye is attachable to the apparatus (), wherein, when the adapter () is attached to the apparatus (), a second additional property of the eye is measurable.

Topograph

In a cylindrical knife holder rotatable about its longitudinal axis, at least one groove is present. The groove extends in the direction of the longitudinal axis of the knife holder. Inserted exchangeably in this groove is a perforating knife, the perforating edge of which protrudes over the peripheral surface of the knife holder. The perforating knife, which can be clamped in the groove by a releasable clamping device, is supported, at its end lying opposite the perforating edge, on a stop element disposed in the groove. The stop element rests on supporting elements distributed over the length of the groove, which are adjustable in directions running transversely to the longitudinal extent of the groove. The supporting elements define the once set radial position of the perforating knife.

Apparatus for the cross-perforation or cross-cutting of continuous material webs

In order to punch a moving material web there are two punching units present, which are arranged one after another in the direction of movement of the material web. Each punching unit has two punching tools, which interact with a rotatably mounted back-pressure cylinder that can be driven. The punching tools are arranged on a rotatably mounted drive shaft that can be driven, and their position can be adjusted in the direction of the longitudinal axis of the latter and locked in various working positions. Each punching tool has a cylindrical base, to the periphery of which a punching strip which is provided with at least one punching shape is fixed such that it can be replaced. The drive shafts can be driven independently of the associated back-pressure cylinder.
