摘要： An optical fiber collimator array includes an optical fiber array block and a microlens array substrate. The optical fiber array block includes an angled surface and is configured to receive and retain a plurality of individual optical fibers, which carry optical signals. The microlens array substrate includes a plurality of microlenses integrated along a microlens surface and a sloped surface opposite the microlens surface. The microlens surface is coupled to the angled surface such that the optical signals from the individual optical fibers are each collimated by a different one of the integrated microlenses.

摘要： An alignment procedure aligns the components of an arrayed optical fiber collimator and reduces losses associated with the collimator. Initially, an optical fiber array block including a plurality of individual optical fibers is received and retained. Next, a microlens array substrate including a plurality of microlenses integrated along a microlens surface and a substrate surface opposite the microlens surface is received and retained. Then, at least a portion of a first light receiver that is positioned to receive a light beam from at least one of the integrated microlenses is received and retained. Next, at least one light beam is provided from the light source to at least one of the plurality of individual optical fibers. Then, the position of at least one of the microlens array substrate and the optical fiber array block is adjusted in relation to each other to maximize the optical power of the light beam received by the first light receiver.

摘要： A POF includes an inner core having a refractive index distribution and an outer core provided on periphery of the inner core. A ratio Ra/Rb of an outer diameter of the inner core to the outer core satisfies 0.67≦(Ra/Rb)≦0.87 such that an outgoing beam from an end of the POF may have a parallel area of at least 200 μm. Thus a space between the end for exiting the exit light and a light receiving device can be kept at least 200 mm without members or devices for collimating.
摘要翻译： POF包括具有折射率分布的内芯和设置在内芯的周边上的外芯。内芯与外芯的外径的比Ra / Rb满足0.67 <=（Ra / Rb）<= 0.87，使得来自POF端部的输出光束可具有至少200μm的平行面积。因此，用于离开出射光的端部和光接收装置之间的空间可以保持至少200mm，而没有用于准直的构件或装置。

摘要： A concentration measuring method and an apparatus measures the concentration of an objective solvent in a mixed solution by flowing a mixed solution through a tube, transmitting light through the mixed solution as it flows through the tubing and measuring the quantity of light transmitted through the fluid. The concentration of the objective solvent in the mixed solution is measured on the basis of either the quantity of light transmitted, the diameter of a light beam received, or a point of convergence of the light transmitted through the mixed solution. These factors being dependent on the concentration of the objective solvent in the mixed solution.
