Abstract: Multiple colors of light emitted by an assembled light emitting diode (LED) based illumination device is automatically tuned to within a predefined tolerance of multiple target color points by modifying portions of wavelength converting materials associated with each color. A first color of light emitted from the assembled LED based illumination device in response to a first current is measured and a second color of light emitted from the assembled LED based illumination device in response to a second current is measured. A material modification plan to modify wavelength converting materials is determined based at least in part on the measured colors of light and desired colors of light to be emitted. The wavelength converting materials may be selectively modified in accordance with the material modification plan so that the assembled LED based illumination device emits colors of light that are within a predetermined tolerance of target color points.

Abstract: A method for determining spectral characteristics of an object is disclosed. A probe is positioned in proximity relative to the object. The probe provides light from at least first and second light sources positioned first and second distances from a central light receiver. The first light source and the central light receiver define a first critical height from the surface below which no specularly reflected light from the first light source is received by the central light receiver, and the second light source and the central light receiver define a second critical height from the surface below which no specularly reflected light from the second light source is received by the central light receiver. The first critical height is different from the second critical height.

Abstract: A spectroscopy system comprises a tunable semiconductor laser, such as an external cavity laser, that generates a tunable signal. A detector is provided for detecting the tunable signal after interaction with a sample. In this way, the system is able to determine the spectroscopic response of the sample by tuning the laser of the scan band and monitoring the detector's response. An integrating device, such as an integrating sphere, is interposed optically between the tunable semiconductor laser and the detector. This integrating device is used to mitigate the effects of parasitic spectral noise, such as noise that is generated by speckle or the combination of single-and multi-mode optical fibers in the transmission link between the tunable semiconductor laser and the detector.
