现代FTIR仪器能够获得非常低水平的噪声,它使样品处理有可能出现新的技术。从方形象变为圆形象使得测量小样品光谱的辅助装置可有新颖的和简单的设计。木文将讨论小样品的透射和反射光谱的测量问题。为了测量不均匀样品的不同部位的光谱,红外显微镜是非常有用的工具,因为它可以清楚地辨认要检测的部位。然而,复杂的传递光学元件的效率比较低。虽然遮蔽一个样品的放大象是很方便的,但在要检测区域的范围内会产生显著的不准确性。本文将对显微镜和非常简单的透镜聚光器作一比较。
Modern FTIR instruments are capable of very low levels of noise, making it possible to sample new techniques for sample processing. The change from a square image to a circular image makes it possible to have novel and simple designs of ancillary devices that measure the spectrum of small samples. Mu Wen will discuss the measurement of transmission and reflection spectra of small samples. In order to measure the spectrum of different parts of an inhomogeneous sample, an infrared microscope is a very useful tool because it clearly identifies the site to be detected. However, complex delivery optics are less efficient. Although it is convenient to mask the magnification of a sample, significant inaccuracies can occur in the area of the area to be examined. This article compares microscopes to very simple lens concentrators.
