    摘要: Transmission spectrometers require low levels of background light so that the signal to noise ratio is increased, and also require stable performance over wide temperature ranges. Light reflected by the transmission grating can result in increased background levels. One approach to reducing the background level is to orient the transmissive diffraction grating so that light reflected by the grating is reflected out of the diffraction plane. The temperature-induced wavelength drift of a transmission spectrometer can be due to the frame upon which the transmission grating is mounted. The wavelength drift is reduced by allowing the thermal expansion of the grating to be independent of the frame.

    摘要: The present invention relates to fiber bundles and methods for making fiber bundles. According to one embodiment of the invention, a fused fiber bundle has a terminal section ending with an endface, and includes a plurality of optical fibers, each of the optical fibers having a terminal segment ending with a proximal end, and a distal end; and a cellular holding structure, the cellular holding structure including a cellular web portion having a plurality of longitudinal cells arranged substantially in parallel and surrounded by a web material; and a tube portion surrounding the cellular web portion. The terminal segments of the optical fibers are arranged substantially in parallel, and the terminal segment of each optical fiber is disposed in a longitudinal cell of the cellular holding structure and substantially fused to the web material, thereby forming the terminal section of the fused fiber bundle.
