High- and low-temperatur IR/UV/Vis-Spectrometer

所要求的设备是一台光谱仪，用于收集远红外、中红外、近红外以及紫外和可见光范围（维斯）的温度相关数据。高分辨率傅里叶变换（FT）光谱仪配备了用于不同光谱范围的必要分束器和检测器，可通过计算机控制将其引入光路。新的光谱仪是为了取代现有的装置，该装置是1980年制造的，由于无法再采购必要的备件，只能在有限的范围内使用。此外，采购的光谱仪旨在扩大可用的温度范围，从而以兼容的方式补充不莱梅大学材料分析设备中心的研究可能性。光谱范围FIR，MIR和NIR可以在10 K至300 K的温度范围内通过新的He闭合循环系统操作，并且从大约100 K至300 K。100 K到870 K之间。应采购加热反射装置，用于UV/维斯测量。

The requested device is a spectrometer for the collection of temperature-dependent data in the far infrared (FIR), mid-infrared (MIR), near infrared (NIR), as well as in the ultraviolet (UV) and visible range (Vis). The high-resolution Fourier transform (FT) spectrometer is equipped with the necessary beam splitters and detectors for the different spectral ranges, which can be brought into the beam path by computer control. The new spectrometer is intended to replace an existing device, which was manufactured in 1980 and can increasingly only be used to a limited extent, as necessary spare parts can no longer be procured. In addition, the spectrometer to be procured is intended to expand the usable temperature range and thus complement the investigation possibilities within the material analytical device center of the University of Bremen in a compatible way. The spectral ranges FIR, MIR and NIR can be operated in the temperature range from 10 K to 300 K by means of a new He-Closed-Cycle system and from approx. 100 K to 870 K with a temperature cell. A heated reflection unit is to be procured for measurements in UV/Vis.
