The use of Index-Matching Fluid between two optics virtually eliminates the reflection losses associated with the glass-air interface. The fluid may also be used to strip cladding modes from a bare fiber or to terminate fibers by dipping the fiber into the liquid. Unlike silicone-based fluid/gel, which is very difficult to remove completely, Newport’s Index-Matching Fluid has a refractive index of 1.52 at 589 nm and can be removed simply with acetone. While the liquid will not evaporate, it is designed to be used on a temporary basis. Available in 6 cc syringes. 100 cps viscosity.


在两个光学元件之间使用指数匹配流体，实际上消除了与玻璃-空气界面相关的反射损耗。这种液体也可用于从裸纤维中剥离包层模态，或通过将纤维浸入液体中来终止纤维。与硅基液/凝胶很难完全去除不同的是，纽波特的指数匹配液在589 nm处折射率为1.52，可以用丙酮简单去除。虽然这种液体不会蒸发，但其设计用途是暂时的。可提供6毫升注射器。100 cps粘度。
