Abstract: Heat-reflecting adhesive tape (1), preferably for wrapping elongate material such as, more particularly, leads or cable harnesses, having a tapelike backing (2) composed of an assembly comprising at least one first layer (2a), formed by a glass fabric having a basis weight of 30 to 200 g/m2, and at least one second layer (2b), formed by a metallic layer having a thickness of 10 to 40 ?m and a thermal effectiveness to SAE J2302 at 350° C. of greater than 45° C., and having a pressure-sensitive adhesive coating (3) applied at least to one side of the backing (2), the flexural rigidity of the adhesive tape in longitudinal and transverse direction being less than 500 mN, preferably less than 300 mN (as measured with a Softometer KWS basic 2000 mN from Wolf).

Abstract: The invention relates to a transmitted-light base (1) for illuminating an object (15) for imaging through a zoom microscope (21), the transmitted-light base (1) comprising an integrated light source (3) having an associated electrical power regulation system (31) for generating a suitable radiation flux, and means (5, 6), capable of being added downstream, for generating a specified spectral intensity distribution. To allow compensation for brightness changes of low dynamic range, such as those occurring in particular during zooming, a continuously controllable mechanical brightness regulator (4) is proposed which is activatable by means of an associated adjustment device (41) in such a way that the illumination intensity of the transmitted-light base (1) is controllable with no change in the spectral intensity distribution.
