Abstract: Varying the optical absorption of an electrochromic device in situ allows optimal control over the depth and quality of laser patterning lines when patterning electrochromic devices. Accordingly, an electrochromic device comprises a target conductive layer, an absorbing electrochromic layer formed below the target layer, and an electrolyte layer formed below the absorbing electrochromic layer. The absorbing electrochromic layer is placed in a darkened state, and the target layer is laser ablated using a wavelength that is minimally absorbed in the target layer and a fluence level that does not ablate layers of the electrochromic device that are below the absorbing electrochromic layer. The absorbing electrochromic layer is placed in the darkened state by applying a predetermined control voltage to the electrochromic device, forming the electrochromic device by dark-state deposition, or forming an electrochromic device that is in its darkened state in an equilibrium state.

Abstract: A window assembly comprises a first conductive material layer, an electrochromic stack, a second conductive material layer and a seal. The first conductive material layer is formed on a substrate and comprises at least two zones electrically isolated from each other. The electrochromic stack is formed on a first selected zone of the first conductive material layer to overlap an edge of a second selected zone of the first conductive material layer. The second conductive material layer is formed on the electrochromic stack to overlap an edge of the second selected zone. A first bus bar is formed on the second selected zone to be within a sealed volume of the window assembly. A second bus bar is formed on the first selected zone to be outside the seal volume of the window assembly. The seal defines the sealed volume of the window assembly and seals the window assembly.

Abstract: A light source assembly comprises: a light pipe and one or more tapered light collectors operative to reduce the angular distribution of light entering the light pipe from light sources at one or more ports. Dichroic filters and angle-dependent, wavelength selective pass filters control light flow into and through the light pipe. The tapered light collector is operative to reduce the angular distribution of light entering the light pipe. At least a first dichroic filter positioned in the light pipe optically between first and second light entrances is operative to pass first color light from the first light source toward the light port, and to reflect second color light from the second light source toward the light port.

Abstract: A light source assembly (212) for providing a homogenized light beam (224) includes a first light source (234), a second light source (236), and an optical pipe (228) that defines a pipe passageway (228A). The first light source (234) generates a first light (234A) that is directed into the pipe passageway (228A) at a first region (228I). The second light source (236) generates a second light (236A) that is directed into the pipe passageway (228A) at a second region (228H) that is different than the first region (228I). The optical pipe (228) homogenizing the first light (234A) and the second light (236A). Additionally, the light source assembly (212) can include a third light source (238) that generates a third light (238A) that is directed into the optical pipe (228) at a third region (228G) that is different than the first region (228I) and the second region (228H).

Abstract: Improved calibration of optical wavelength measuring instruments. In a first embodiment, improved calibration is achieved in an optical wavelength measuring instrument by performing calibration measurements at a plurality of known wavelengths and using an average calibration constant derived from the plurality of measurements. In a second embodiment, improved calibration is achieved by performing calibration measurements at a plurality of known wavelengths and calculating a linear or higher order calibration model, or a periodic model. These approaches may be extended by segmenting the wavelength range and using different calculated calibration values, or different calibration models, for each segment.

Abstract: Wavelength reference standard using multiple gasses and calibration methods using same. A wavelength reference using absorption lines of multiple gasses provides stable reference wavelengths over multiple regions of interest of the optical spectrum. The gasses may be in separate cells or combined in one cell. Improved calibration using the reference is achieved by performing calibration measurements at a plurality of known wavelengths and using an average calibration constant derived from the plurality of measurements. In a second embodiment, improved calibration is achieved by performing calibration measurements at a plurality of known wavelengths and calculating a higher order calibration model, such as a least-squares linear fit. Both approached may be extended by segmenting the wavelength range and using calculated calibration values for each segment.
