Setting up fluorescence, Raman, and absorption spectroscopy experiments often encounters difficulties such as complicated optical paths, complex sample clamping, the overwhelming of weak signals by stray light, and the large size of the sample chamber occupying a significant amount of space on the optical platform, as well as a lengthy system setup process. The Sevan Optoelectronics 7ISC2 optical fiber sample chamber, a lightweight four-port optical fiber coupling sample container, provides a compact, flexible, and high-signal-to-noise ratio sample testing solution for fiber-optic spectroscopy systems. It is an ideal complementary component for university laboratories, material testing, and spectroscopy teaching experiments.
The 7ISC2 is compact in size, with an overall dimension of only 60×45×38mm and a weight of only 0.07kg. Its small body does not occupy platform space and can be flexibly embedded in various small optical path systems. The equipment is equipped with four optical entrances and exits, all supporting SMA905 standard optical fiber sockets. The optical fibers can be directly introduced and exported to the beam, freely setting up transmission, reflection, absorption, fluorescence, and Raman types of test optical paths. The light source entry and signal collection can be flexibly allocated to ports, and the freedom of optical path layout is greater.
The sample chamber is equipped with standard slots, suitable for 12.5mm×12.5mm conventional colorimeters. Liquid samples can be directly placed for testing without the need for additional custom fixtures. Sample replacement is fast, significantly reducing sample pre-treatment and adjustment time. The core highlight is the pre-installed HB600 long-wave pass filter, which can effectively filter out stray light interference caused by excitation light and separate the target fluorescence and Raman scattering signals, significantly improving the spectral signal-to-noise ratio; combined with the Sevan monochromator and 7IGF10 fixed-grating spectrograph, a small fluorescence and Raman spectroscopy measurement system can be quickly set up without complex multi-level filtering optical paths, and the experiment can be quickly implemented.
The modular fiber access design significantly reduces the system modification threshold. The flexible transmission of optical fibers ensures no complex spatial alignment is required, and beginners can quickly complete the optical path debugging. It is highly suitable for teaching experiments, material screening, and liquid spectroscopy qualitative and quantitative detection. Whether it is the research of topics in university physics, chemistry, and materials laboratories, the optical property testing of thin films and liquid samples, or the development of small-scale spectroscopy detection prototypes, the 7ISC2 can be quickly connected to the existing fiber-optic spectroscopy system and quickly obtain stable and repeatable spectral data.
As a domestic precision optical mechanical component, Sevan Optoelectronics has been deeply engaged in optical instrument manufacturing for over twenty years. The structure of the 7ISC2 sample chamber is solid and stable, with high consistency of optical interfaces, complete supporting equipment, software ecosystem, and convenient after-sales debugging response, achieving a reliable replacement for similar imported sample chambers.
Spectroscopy experiments are not bound by cumbersome optical paths. The Sevan 7ISC2 optical fiber sample chamber simplifies the spectral sampling process with a micro body, four-way fiber coupling, and built-in anti-jamming capabilities, capturing weak optical signals, and using a lightweight solution to help each spectroscopy measurement be efficiently implemented.
