波恩仪器销售德国Sentech红外光谱椭偏仪SENDIRA 半导体检测设备

外光谱椭偏仪具有大面积水平样品台，马达驱动可变入射角度，支持样品水平扫描，吹氮气去水蒸气保护红外光学透镜。提供新材料如有机物半导体, OLED和有机物光谱范围内振动光谱的优良结果。提供复杂多层膜上化学、机械、电气、光学信息。即可作为研发工具，也可作为质量控。

椭偏振动光谱

利用红外光谱中分子振动模的吸收带，可以分析薄膜的组成。此外，载流子浓度可以用傅立叶红外光谱仪FTIR测量。

傅立叶红外光谱仪FTIR完全适用

集成赛默飞世尔Thermo Fisher制造的型号FTIR iS50红外光谱仪。它也适用于一般的振动光谱。

光谱椭偏仪SENDIRA用于测量薄膜厚度，折射率，消光系数以及体材料，单层和多层堆叠膜的相关特性。特别是覆盖层下面的层在可见范围内是不透明的，现在也可以进行测量。同时可以分析材料的组成和大分子基团和分子链的走向。

SENTECH光谱椭偏仪SENDIRA是专门为红外应用(FTIR)设计的。紧凑型测量台包括椭圆仪光学部件，计算机控制角度计，水平样品台，自动准直透镜，商用FTIR和DTGS或MCT探测器。FTIR在400 cm-1 ～6,000 cm-1 (1.7 µm – 25 µm)光谱范围内提供了极好的精度和分辨率。

光谱椭偏仪SENDIRA主要用于薄层的振动光谱分析。应用范围从介质膜、TCO、半导体膜到有机膜层。SENDIRA是由SpectraRay/4 软件操作，另外还提供了FTIR软件。

SE 900-50 红外光谱椭偏仪替代型号

Basics The ellipsometer measures in reflection mode the optical response of a sample using polarized light.
The sample properties change the polarization state of the reflected light. Amplitude ratio and phase difference of the Fresnel reflection coefficients rpand rsare used to investigate material composition, molecule orientation, film thickness and optical constants of single films and layer stacks.

Benefits of SENDIRA IR spectroscopic ellipsometer
