    Abstract: A photometric device (1) measuring light emitted from a measuring object such as a display (2) includes two types of filters including interference filters (20X, 20Y, and 20Z) and an LVF (21), a disk (22) supporting the interference filters and the LVF, a motor (23) rotatably drive the disk to cause the light emitted from the measuring object to scan the interference filters and the LVF sequentially, a photoreceptor (13) converting light passed through the interference filters and light passed through the LVF to an electrical signal, a photometric controller (14) outputting photometric information based on the electrical signal of the light passed through the interference filters and converted by the photoreceptor and the electrical signal of the light passed through the LVF and converted by the photoreceptor.

    Abstract: A photometric device (1) measuring light emitted from a measuring object such as a display (2) includes interference filters (20X, 20Y, and 20Z) selectively transmitting a particular wavelength corresponding to a respective one of tristimulus values, an LVF (21) separating and transmitting incident light, a disk (22) supporting the interference filters and the LVF, a motor (23) rotatably drive the disk to cause the light emitted from the measuring object to scan the interference filters and the LVF sequentially, a photoreceptor (13) converting light passed through the interference filters and light passed through the LVF to an electrical signal, and a photometric controller (14) outputting photometric information based on the electrical signal of the light passed through the interference filters and converted by the photoreceptor and the electrical signal of the light passed through the LVF and converted by the photoreceptor.

    Abstract: A diffraction grating and a prism with the appropriate characteristics are employed to provide a combined dispersive characteristic that is substantially linear over the visible spectrum. Radiation from the grating and prism is collimated by a lens towards a detector array. The or a telecentric stop between the grating and prism is placed at a focal point of the lens in a telecentric arrangement so that equal magnification is achieved at the detector array. If the detector array is replaced by a plurality of optical channels, a multiplexer/demultiplexer is obtained.
