An apparatus for imaging cells including a culture chamber, in which a cultivation sub-structure is placed, imaging optics, and actuators for providing the relative movement of the cultivation substructure and the imaging optics in such a way that the imaging optics is used to image different sites in the substructure. The cultivation substructure is isolated as a subchamber of its own that is separate from the culture chamber, and imaging is carried out by moving the imaging optics and the subchamber in relation to each other.

Apparatus for imaging cells

The invention relates to a method and an arrangement for measuring the geometry of grooves in an elongated element, which grooves () extend as continuous grooves over the whole length of the elongated element (), circling around the element, in which method the surface of the elongated element is scanned by of a camera (). In order to achieve simple non-contact measurement, the elongated element () is arranged to travel at the vertex through an annular biconical minor or through a biconical bevelled mirror () comprising several plane mirrors, and through a plane mirror structure () arranged at an oblique angle relative to the direction of travel of the elongated element (). An annular laser beam is directed to the plane mirror structure in such a way that the plane mirror structure () reflects the beam onto the surface of the elongated element () through the outer surface () of the biconical mirror or bevelled cone mirror. The image of the surface profile of the elongated element () produced from the surface of the elongated element () by means of the inner surface () of the biconical mirror or bevelled cone mirror () is turned to one side by means of the plane mirror structure () to allow the study of the groove geometry.
