使用激光粒度仪先测量背景原因是什么？今天济南微纳小编给大家介绍一下。
What is the reason for measuring the background with a laser particle sizer www.jnwinner.com? Today Ji'nan micro small series to introduce.
背景是激光透过纯净介质后在探测器上形成的固定的光信号，主要是探测光经过路径上的颗粒物（例如，样品池窗口玻璃和透镜表面上的污渍、内部的瑕疵、介质中的残余颗粒等）对光的散射引起的。
The background is fixed through the laser light signal detector in pure medium after formation, mainly through the probe particles on the path (for example, sample pool window and lens surface stains, internal defects, medium residual particles) of light scattering caused by.
使用激光粒度仪测量背景的目的是在粒度测试（有样品）是扣除这些固定的、与样品无关的信号，以消除样品散射以外的杂散光对测试结果的影响。
The purpose of measuring the background with a laser particle sizer is to remove the fixed, sample independent signals in the particle size test (with samples) to eliminate the effects of stray light other than the sample scattering on the test results.
