Chemical, physical and optical properties of small solid particles are widely utilized in our everyday merchandises. For example, tailored particles embedded in paper or cosmetics improve the visual appearance of the products substantially. As a consequence of the small size of particles, one particle characterization tool is a microscope. It may provide e.g. the particle size, shape and the refractive index. The determination of the refractive index, using the microscope, typically exploited the so-called immersion liquid method. In this review, we provide an overview of non-imaging immersion matching techniques including immersion liquid set, the temperature, the wavelength, the double variation and the liquid evaporation methods. The basic features, benefits and limitations of each technique have been described followed by examples of potential applications in a quality monitoring of particle suspensions and colloids in industry.
小固体颗粒的化学、物理和光学性质在我们的日常商品中得到了广泛应用。例如，嵌入纸张或化妆品中的定制颗粒能显著改善产品的视觉外观。由于颗粒尺寸小，一种颗粒表征工具是显微镜。它可以提供例如颗粒大小、形状和折射率等信息。使用显微镜测定折射率通常采用所谓的浸液法。在本综述中，我们概述了非成像浸液匹配技术，包括浸液装置、温度、波长、双变量和液体蒸发法。描述了每种技术的基本特征、优点和局限性，随后列举了其在工业中颗粒悬浮液和胶体质量监测方面潜在应用的实例。
