Thus, an ND filter having satisfactory front surface reflection characteristics and rear surface reflection characteristics can be stably obtained while the transmittance of 4% or more and 11% or less is maintained with respect to the entire visible region (400 nm or more and 700 nm or less).

  • Patent number: 7706090
    Abstract: A diaphragm device with which individual wavelengths or ranges of wavelengths in the path of a beam of spectrally dispersed light can be suppressed. Such a diaphragm device comprises at least one array of diaphragms, wherein the individual diaphragms of the array are arranged in a definite relation to each other and may be coupled in the path of the beam and each diaphragm of the array in the coupled state is arranged in a given relation to an individual wavelength or a range of wavelengths.

  • Publication number: 20090310131
    Abstract: A Raman spectroscopy system has a filter arrangement comprising two filters (16, 26A) in series, to reject light of the illuminating wavenumber from the scattered light of interest. The filters are tilted and have different characteristics for light of first and second different polarisation states. To counter this, the filters are arranged so that their respective effects on the respective polarisation states at least partially cancel each other out. This may for example be done by arranging their tilt axes (32, 34) orthogonally to each other.

  • Publication number: 20090296247
    Abstract: An apparatus and methods for converting a monochrome night vision or other electro-optical device into one that provides a sensation of full color, including from red to blue with white and black. The method provides color images from an electro-optical device in which the image data from the electro-optical device contains brightness information of an area being viewed by the device without separate color information. Such a method includes operably coupling an optical channel system to the electro-optical device and configuring the optical channel system and arranging the optical channel system with respect to the electro-optical device so two color informational channels are provided to the viewer, whereby the two informational channels formed by said configuring and arranging of the optical channel system are such that the viewer sees a color image.

    Abstract: Systems and methods are disclosed that include overlapping a first portion of a first piece of flexible filter material and a second portion of a second piece of flexible filter material. In these systems and methods, the first and second pieces of flexible filter material produce a desired change in a characteristic of a light beam. These systems and methods can include clamping the first portion and the second portion between a first element and a second element. In addition, these systems and methods can include producing ultrasonic vibrations in the first element that promotes a bond between the first and second piece of flexible filter material.

  • Publication number: 20090195773
    Abstract: A filter arrangement can transmit and/or reflect light emanating from a moving object so that the emanating light has time variation, and the time variation can include information about the object, such as its type. For example, emanating light from segments of a path can be transmitted/reflected through positions of a filter assembly, and the transmission functions of the positions can be sufficiently different that time variation occurs in the emanating light between segments. Or emanating light from a segment can be transmitted/reflected through a filter component in which simpler transmission functions are superimposed, so that time variation occurs in the emanating light in accordance with superposition of two simpler non-uniform transmission functions. Many filter arrangements could be used, e.g. the filter component could include the filter assembly, which can have one of the simpler non-uniform transmission functions.

  • Patent number: 7557992
    Abstract: A multi-mode color filter 400 having an inner hub region 402 used to mount the color filter 400 to a motor shaft. A first track 404 and a second track 406 of color filter segments are formed on the color filter, as is an optional clear track 406. The first and second tracks each have a different set of color filters. One set of filters is chosen to improve image brightness, another set is selected to improve color saturation. Typically, the set of filters used to improve brightness includes one or more clear segments, while the set of filters selected to improve color saturation does not. Depending on the image being projected, the user or the display controller moves the color wheel to select a particular filter set.

  • Publication number: 20080284982
    Abstract: Spectral separation filters for channels of a 3D image projection incorporate passbands of primary colors. In at least one of the filters, passbands are present in more than 3 primary colors. A set of two filters include a first filter having passbands of low blue, high blue, low green, high green, and red, and a second filter having passbands of blue, green, and red. The additional primary passbands of the first filter allow for an increased color space in projections through the filters compared to filters only having red, green, and blue primaries. The added flexibility of the increased color space is utilized to more closely match a color space and white point of a projector in which the filters are used.

  • Patent number: 7440205
    Abstract: A dimming system (300) for dimming electromagnetic radiation intensity of a radiating unit, such as e.g., an optical system. The dimming system (300) is adjusted to provide a constant electromagnetic radiation intensity over the cross-section of the impinging electromagnetic radiation beam by providing at least two dimming units (320, 330) each having a spatially variable position-dependent dimming behavior, such that the degree of dimming for the whole cross-section can be chosen to be a fixed selectable dimming factor. The dimming units (320, 330) may be based on spatially variable position-dependent dimming devices based on transparent substrates having a coating with a position-dependent varying transmission/reflection coefficient, on spatially variable position-dependent diffusing devices or on polarizer devices.
