During the setup of the spectral experiment, the samples come in various forms such as solids, films, powders, and liquids. Frequent changes of sample holders and reconfiguration of the optical path not only consume a lot of debugging time but also easily introduce stray light and cause the optical path to shift, thereby affecting the repeatability of the spectral data. The 7ISC1 multi-functional sample chamber from Sifan Optoelectronics is specifically designed for monochromators and spectral detection systems. It integrates multi-mode measurement capabilities for transmission, reflection, and scattering. With just one sample chamber, it can complete the optical property tests of various types of samples, making it a core component for integrating scientific research laboratories and optical detection equipment.
The 7ISC1 adopts a modular open optical cavity design, compatible with various sample clamping methods. The cavity can be equipped with standard colorimetric dish holders and directly hold liquid samples to complete ultraviolet-visible-near-infrared transmission spectral tests. After changing the sample platform, films, glass substrates, solid blocks, and powder samples can all be fixed, supporting normal incidence reflection, diffuse reflection measurements, and meeting the requirements for characterizing the absorption, reflection, and scattering properties of materials. The sample cavity supports quick opening, convenient sample retrieval, and does not require disassembling the entire optical path for sample replacement, significantly reducing the workload of re-calibrating the optical path.
The cavity is equipped with multiple optical windows in multiple directions, suitable for Φ25mm optical components, and can be equipped with filters and window plates as needed to suppress stray light interference and improve the signal-to-noise ratio. It is compatible with all of Sifan's monochromators and spectrometers systems, and can be connected to free-space optical paths or combined with fiber coupling components to expand fiber sampling schemes, flexibly integrating into existing spectral testing platforms. The mechanical structure of the cavity is stable, with high positioning accuracy, firm sample clamping, and the optical path is less likely to shift after repeated sample loading, ensuring stable and reproducible experimental data, meeting the requirements of paper-level experiments and industrial sample screening.
The application scenarios are extensive: university laboratories in materials, chemistry, and optoelectronics, for transmission/reflectance spectroscopy research of films, coatings, and powder materials; for the development of optoelectronic materials, testing the optical response of substrates and coated samples; for teaching spectroscopy experiments, rapid screening of new materials, and qualitative and quantitative detection of optical samples. Whether it is for scientific research project experiments or the integration of small-scale detection equipment, the 7ISC1 multi-functional sample chamber can simplify system setup, eliminating the need to purchase multiple sample chambers for different samples, and reducing equipment procurement costs.
Based on Sifan Optoelectronics' over two decades of precise optical machine research and development experience, the 7ISC1 multi-functional sample chamber has reliable processing accuracy, a durable mechanical structure, complete accessories, and supports custom sample holders and windows. Domestic alternatives to imported similar sample chambers are available, and the accompanying debugging, technical support, and response are efficient.
One sample chamber can handle various spectral measurements of samples. The 7ISC1 multi-functional sample chamber, which combines transmission, reflection, and scattering testing modes, flexibly adapts to solid, liquid, film, and powder samples in various forms, reduces the cost of optical path setup, simplifies the experimental process, and makes spectral sample characterization more efficient and stable.
