使用激光粒度儀先測量背景原因是什么？今天濟南微納小編給大家介紹一下。
What is the reason for measuring the background with a laser particle sizer www.qufutj.com? Today Ji'nan micro small series to introduce.
背景是激光透過純凈介質后在探測器上形成的固定的光信號，主要是探測光經過路徑上的顆粒物（例如，樣品池窗口玻璃和透鏡表面上的污漬、內部的瑕疵、介質中的殘余顆粒等）對光的散射引起的。
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.
使用激光粒度儀測量背景的目的是在粒度測試（有樣品）是扣除這些固定的、與樣品無關的信號，以消除樣品散射以外的雜散光對測試結果的影響。
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.
