20090009899 | Near Infrared Ray Absorbing Filter, Optical Filter for Plasma Display and Plasma Display Panel - A near infrared ray absorbing filter is a film gained by biaxially oriented polyester having a near infrared ray absorbing agent, and the melting point of this polyester is no higher than 230° C. The optical filter for a plasma display is provided with a near infrared ray blocking layer made of polyester containing a near infrared ray absorbing agent and an image quality correcting layer made of polyester containing a compound which absorbs visible light having an absorption maximum wavelength in a range from 560 nm to 600 nm. These layers are layered through an integrated process by means of a co-extrusion method, according to which these layers are melted and extruded together from a co-extrusion process, and thus, a biaxially oriented film is formed. The melting point of the polyester in these layers is no higher than 230° C. | 01-08-2009 |
20090296247 | Method for providing color images from a monochromatic electro-optical device using two optical channels and systems, apparatuses and devices related thereto - 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. Such methods and apparatuses of the present invention provides a sensation of full color image, including from red to blue with white and black, to the viewer. | 12-03-2009 |
20090316286 | Aligned Narrowband Optical Filters having Flat Passbands and Comprising Offset Cascaded Broadband Optical Filters - A cascaded pair of broad bandwidth optical filters provides an overlap in pass-bands that forms a flat, narrow band optical filter. A first band-pass filter is operable to receive the optical signal and to transmit a first portion of the optical signal. The second band-pass filter receives the first portion of the optical signal transmits a second portion of the optical signal. The first band-pass filter has a first corner-pass wavelength of λ | 12-24-2009 |
20100079884 | DICHROIC APERTURE FOR ELECTRONIC IMAGING DEVICE - A dichroic filter that for use with an electronic imaging device, such as a camera. The dichroic filter is located in the main imaging lens, and may permit all light to pass through a first portion and be measured by a photosensor, while restricting at least some portions of visible light from passing through a second portion thereof. In this manner, only the non-restricted portions of visible light passing through the second portion may be measured by the associated pixels of the photosensor. The filter may be formed from a first aperture permitting a first set of wavelengths to pass therethrough and a second aperture adjacent the first aperture, the second aperture permitting only a subset of the first set of wavelengths to pass therethrough. The second aperture may be a dichroic mirror or it may be an optical filter of some other type. | 04-01-2010 |
20120262809 | THERMALLY-RESILIENT, BROADBAND OPTICAL ABSORBER FROM UV-TO-IR DERIVED FROM CARBON NANOSTRUCTURES AND METHOD OF MAKING THE SAME - A monolithic optical absorber and methods of making same. The monolithic optical absorber uses an array of mutually aligned carbon nanotubes that are grown using a PECVD growth process and a structure that includes a conductive substrate, a refractory template layer and a nucleation layer. Monolithic optical absorbers made according to the described structure and method exhibit high absorptivity, high site densities (greater than 10 | 10-18-2012 |
20140334026 | LAYERED PHOTOCHROMIC COMPOSITION AND DEVICE - An optical power-limiting passive (self-adaptive) device and method for limiting optical power transmission in lenses and windows, using layers of different photochromic compositions that exploit the full solar ultraviolet (UV) and short visible light spectrum. While a typical single photochromic material is activated by a UV band of wavelengths, e.g. 340 to 380 nm, adding a layer of photochromic material that is activated by an additional band of wavelengths, e.g., 380 to 420 nm, allows the efficient use of a wider band of solar UV and short visible light, e.g., 340 to 420 nm, thus enhancing the photochromic response to solar light. | 11-13-2014 |
20160018575 | COLOR FILTER AND FABRICATING METHOD THEREOF, AND DISPLAY APPARATUS - A color filter and a fabricating method thereof, and a display apparatus are provided. The color filter includes: at least four pixel units, and each pixel unit includes a color filter layer, and the four pixel units are a first pixel unit, a second pixel unit, a third pixel unit and a fourth pixel unit, respectively. A first color filter layer is formed in the first pixel unit, a second color filter layer is formed in the second pixel unit, a third color filter layer is formed in the third pixel unit, a fourth color filter layer is formed in the fourth pixel unit, and the fourth color filter layer is formed by stacking any two materials of the first, second and third color filter layers. | 01-21-2016 |
