preparation example Construction

[0026] The preparation of the refractive index matching liquid is as follows: mixing glycerol and a surfactant in parts by weight, and stirring at normal temperature until it is transparent without flocs, and thus the refractive index matching liquid is obtained. The preparation also includes the step of defoaming the obtained refractive index matching liquid. The defoaming treatment may adopt the following method: the obtained refractive index matching liquid is placed in a vacuum container and vacuumized to remove air bubbles. In the defoaming treatment, the obtained refractive index matching liquid can also be left to stand until the air bubbles dissipate, and the standing time is determined according to the actual time for the air bubbles to dissipate. The defoaming treatment can be carried out after the refractive index matching liquid is prepared, and can also be carried out before the refractive index matching liquid is used.

Abstract

The invention discloses refractive index matching liquid which includes the following raw materials, by weight, 1-99.9 parts of glycerol and 0.1-99 parts of surfactant. According to the refractive index matching liquid, the glycerol is used as a base solution and the surfactant is used as adjuvant. Therefore, the refractive index matching liquid is good in stability and fluidity, small in surface tension, low in cost, easy to manufacture, and good in using effect.

Description

technical field [0001] The invention relates to a refraction fluid, in particular to a refractive index matching fluid. Background technique [0002] In various optical-related detections, it is often necessary to add a refractive index matching liquid between two optical devices to eliminate the influence of the joint interface on the optical performance. Taking the field of optical communication as an example, the development of my country's broadband access and fiber-to-the-home in recent years has led to a sharp increase in the demand for planar optical waveguide chip products. Planar optical waveguide is a technology that uses the optical refractive index of different substances to create optical waveguide channels on the wafer plane, and completes the specific optical communication functions that can only be realized by multiple single optical devices in the past. When testing a planar optical waveguide chip, the chip will be connected to other optical devices such as...
