Abstract: A low-pressure mercury discharge lamp according to the invention is provided with a discharge vessel (1) which encloses a discharge space (2) in a gastight manner and in which a filling comprising mercury is accommodated. The lamp is in addition provided with means (3a, 3b) for maintaining an electric discharge in the discharge space. The discharge vessel is provided with a luminescent layer (5). The lamp generates light during operation with a spectrum which is substantially composed of radiation in a first wavelength region from 590 to 630 nm, in a second wavelength region from 520 to 565 nm, and in a third wavelength region from 430 to 490 nm. The radiation in a wavelength interval from 590 to 600 nm accounts for at least 25 % of the power of the radiation in the entire first wavelength region. As a result, the lamp is an attractive proposition for applications where a mediocre color rendering can suffice.

Abstract: The application describes a method and devices for manufacturing a broadband cholesteric polarizer having a well-defined bandwidth and edge position. To this end, a liquid-crystalline cholesterically ordered layer comprising reactive chiral monomers and reactive nematogenic monomers having a different reactivity is polymerized by exposure to radiation. The invention is characterized in that the intensity of the radiation is increased substantially, preferably by a factor of 10 or more, when a desired edge position of the band is reached. As a result, the bandwidth and egde position of the reflection band reached at that moment are frozen as it were. A monochromatic sensor can be used to determine whether said edge position has been reached, the wavelength used by the sensor corresponding to the wavelength of the desired edge position of the band. Broadband, cholesteric polarizers having a well-defined bandwidth and edge position can very advantageously be used in a display.

Abstract: A device for imaging a turbid medium, for example a breast of a female, comprising a holder for comprising the turbid medium, a light source, a photodetector and a processing unit for deriving the image from the intensities measured is adapted to comprise besides the turbid medium also an adaptation medium having substantial identical optical parameters as the optical parameters of the turbid medium. In this way artefacts in the reconstructed image due to the boundary effect between the turbid medium and the holder can be reduced. When a liquid is used as an adaptation medium a perfect match between the holder and the shape of the turbid medium can be obtained. Further, according to the invention also intensity differences in the image due to different path lengths between light source and photodetector could be equalized.
