Abstract: ABSTRACT OF THE DISCLOSURE                            MULTISPECTRAL SENSOR The invention relates to a multispectral sensor with several filter and sensor elements for different spectral ranges of a radiation to be measure. The object of the invention is to so further develop a multispectral sensor of this type that it can be manufactured as a discreet component with small dimensions and has a high measuring accuracy, whilst obtaining a high output signal.  This object is achieved in that the beam is broken down by a optical device into several partial beams and reflected onto filters.  Behind the filters are located radiation-sensitive elements, which detect the spectral range corresponding to the transmission range of the in each case upstream filter.  The remaining spectral range of the partial beam is reflected by the filter surface towards the other filters.  Thus, each filter is supplied with the associated spectral ranges of all the partial beams.

IPC: G02B5/20
Filed: 1993-09-27
Abstract: The viewing angle and illumination intensity of windows and indicator panels are improved by printing the legends associated with indicator windows on a clear plastic sheet. An opaque ink having a color that contrasts with the color of the printed matter is coated on the backside of the panel with suitable masking so that transparent windows are defined in the panel. A clear tinted ink is coated on the background color coating to impart color to the windows. The next coat is a transparent ink, which contains a white reflective and light-dispersing pigment that makes it translucent. Finally, a coat of a transparent ink is applied and it is cured to produce a textured effect which contributes to the light scattering and diffusing process performed by the white pigment such that when a window is illuminated from the backside, it can be visualized along an optical axis which is almost parallel with the plane of the panel. The various inks that are applied after the windows are created can be combined in many cases to reduce the method to a single coating step. The method can be used to treat large panels where obscuring the individuality of LEDs is sought.
