An inspecting system () includes a stage (), a white light source (), a CCD camera (), a laser diode assembly (), at least one beam splitter (), a photo diode (), and an oscilloscope (). The white light source emits a white light () to illuminate a color filter (). The CCD camera photographs the color filter and is linked with an image processing and displaying device (). The laser diode assembly emits a laser light (). The at least one beam splitter is arranged in a path of the laser light and transmits the laser light to the color filter. The photo diode receives the laser light reflected by the color filter and generates an electronic signal. The oscilloscope is connected with the photo diode and displays the electronic signal. The inspecting system facilitates the convenient and accurate inspection/evaluation of color filters.

Inspecting system for color filters

A 1 X N splitter for single-mode optical fiber includes an individual single-mode optical fiber having its junction end juxtaposed, through a focusing lens/junction element, to the end of a bundle of arbitrarily arranged single-mode fibers which are fused together along a portion of their lengths and which have a total diameter approximately equal to the diameter of the first single-mode fiber. The 1 X N splitter is formed by trimming a limited portion of the cladding from and fusing together in a bundle a plurality of parallel but randomly arranged optical fibers at a fuse region with substantially uniform heat while controllably drawing all the fibers in the bundle at the same time monitoring crosstalk from a single input fiber to all output fibers to draw down the bundle size and to promote uniform crosstalk, then cleaving the fiber bundle at the fused region, abutting and aligning a single-mode optical fiber having cladding of substantially the same diameter as the fused bundle with the cleaved fused bundle and joining the single-mode optical fiber to the cleaved fused bundle with a spot weld which forms a focusing junction. The matched sizing and focusing junction minimizes return losses due to back reflection.

1 X N splitter for single-mode fibers and method of construction

A method for fabricating single-mode and multi-mode attenuators characterized by a high level of wavelength insensitivity. A light source is connected to one end of a fiber and the other end is connected to an optical power meter. The optical power meter is set to a 0 dB reference. The fiber is then cut and the cut ends cleaved to define first and second segments. The ends of the segments are offset and overlapped by an axial distance that is large relative to the fiber diameter. The overlapping ends are heated so that they assume a fused state, and the relative axial positioning of the fiber ends while they are in the plastic state is adjusted to achieve the desired degree of attenuation, as indicated on the meter.
