In the laboratories dedicated to scientific research, on the assembly lines of industrial production, and at the frontlines of field monitoring, spectral analysis technology is evolving towards the "fast, portable, and in-situ" direction. As the core equipment for flexible detection, the fiber optic spectrometer, with its advantages of non-contact measurement, high response speed, and miniaturized design, has become a key support for the digital transformation of various industries. According to the global market research data from GIR, the global market size of fiber optic spectrometers will reach 383 million US dollars in 2024, and is expected to increase to 477 million US dollars in 2031, with a compound annual growth rate of 3.2%, with color measurement and spectral measurement accounting for more than 70% of the total. Beijing Saifan Optoelectronics, having深耕 the field of optoelectronics for 22 years， has顺势推出 7IGF 系列光纤光谱仪产品矩阵，凭借“全波段覆盖、多场景适配、高精度输出”的核心竞争力，打破了海外品牌的垄断，成为国产光纤光谱仪的标杆之选。
1. Technological Innovation： Building a Performance System Suitable for All Scenarios
The core strength of Saifan Optoelectronics' 7IGF series fiber optic spectrometers stems from in-depth insights into optical technology and application requirements， forming three major technical advantages：
Optical performance precision breakthrough： Utilizing holographic grating spectrometry technology and back-sensing CCD/InGaAs array detectors， the 7IGF068-HR high-resolution type， equipped with a 4K pixel CMOS sensor， achieves 200-1100nm full spectral coverage， with a spectral resolution as low as 0.1nm， stray light suppression reaching 1×10⁻³ order of magnitude， dynamic range exceeding 1000：1， and can accurately capture weak spectral signals. The near-infrared series 7IGF10-NIR-MAX will further expand the detection range to 900-2500nm， combined with secondary TEC cooling technology， with a maximum temperature control of -40℃， effectively suppressing dark current noise， and suitable for high-precision detection in complex environments.
Mechanical design efficient and flexible： Adopting modular compact design， the standard model has a volume of only 200×150×80mm and weighs as low as 0.8kg. The portable model is equipped with a lithium battery for 8-hour battery life， meeting the needs of field operations and mobile detection； the industrial-grade model has an IP65 protection level and anti-vibration structural design， which can be directly embedded in the production line for 24-hour continuous operation， solving the pain points of traditional equipment "large size， difficult integration， and poor adaptability".
Intelligent interconnection seamless integration： The entire series is equipped with USB2.0 high-speed data interface and IO communication interface， supporting synchronous control， triggering， and sampling of multiple devices， and can be spliced according to the need for wavelength range； the high-end model opens API interfaces， which can be seamlessly connected with MES， LIMS industrial systems， and combined with the independently developed spectral analysis software to achieve real-time data preprocessing， anomaly warning， and report generation， significantly improving detection efficiency.
2. Scene Empowerment： Full Dimensional Coverage from Laboratory to Industrial Chain
Relying on a rich product range and strong scalability， Saifan's 7IGF series fiber optic spectrometers have deeply penetrated multiple fields such as research， industry， and daily life， becoming indispensable "testing tools"：
Research frontiers： Tsinghua University's Materials College uses the 7IGF068-HS high-speed type fiber optic spectrometer to monitor the photoluminescence spectra of perovskite solar cells in real time， providing key data for material stability optimization； the Institute of Environment of the Chinese Academy of Sciences uses a portable spectrometer carried by drones to build a three-dimensional monitoring network for air pollution， achieving PM2.5 component traceability and dynamic tracking. In cutting-edge research fields such as Raman spectroscopy and plasma diagnosis, the research-grade models possess the ability to capture transient signals at the millisecond level, helping researchers break through technical barriers.
In the industrial manufacturing sector: The BYD new energy vehicle factory uses the 7IGF10-PRO high-performance spectrometer to conduct 100% online inspection of the alloy composition of battery pack welding points, controlling the defect rate to below 0.03%; in the semiconductor industry, the equipment detects the thickness and uniformity of the wafer coating to ensure the quality of chip manufacturing; in the photovoltaic industry, it cooperates with the Sevan testing system to complete battery efficiency assessment, helping to increase production capacity.
In the field of people's livelihood security: The environmental protection department uses its rapid detection of organic pollutant absorption characteristics in water bodies to achieve real-time monitoring of water quality; in the biomedicine field, the near-infrared model can penetrate 2cm of biological tissue, providing precise data for non-invasive blood glucose monitoring and drug component analysis, with the clinical trial error precision controlled within ±15%; in the field of cultural relic protection, the portable spectrometer realizes non-destructive detection of cultural relics, restoring the material and age information of the objects.
III. Brand endorsement: 22 years of accumulation, establishing a benchmark for domestic instrument trust.
As a national high-tech enterprise founded in 2004, Sevan Optoelectronics has always taken "technological innovation" as the core, accumulating 33 patents and 34 software copyrights. In 2022, it was awarded the title of "Specialized, Innovative, and High-Scalability" enterprise in Beijing. Its products are exported to multiple regions including Europe and Southeast Asia, serving over 2000 research institutions and enterprises, with a core customer repeat purchase rate of 45%.
Quality guarantee: The products have passed ISO9001 quality system certification. Key components (gratings, detectors) offer a 3-year warranty. They strictly follow industry standards and undergo multiple extreme environment tests to ensure long-term stable and reliable operation.
Service upgrade: A nationwide service network has been established, achieving 7×24-hour response and ≤4-hour local service, providing customers with a full life cycle service from selection guidance, on-site training to maintenance calibration. A user from a certain aerospace institute commented: "The Sevan engineers stayed on-site for 3 consecutive weeks, customizing a multi-channel synchronous acquisition scheme, reducing the time alignment error of spectral data and electron microscope images to less than 0.1 seconds."
Policy alignment: Responding to the national "14th Five-Year Plan" for intelligent manufacturing, it helps promote the domestic substitution of precision instruments, and its photovoltaic testing system is included in the Ministry of Industry and Information Technology's "Photovoltaic Industry Technology Equipment Recommended Catalogue", becoming a representative of domestic spectrometer instruments going global.
Conclusion: Through light as a medium, intelligence unlocks the new future of detection.
From microscopic exploration in the laboratory to quality control on industrial production lines, from the protection of the environment to the guarantee of life health, the 7IGF series of fiber optic spectrometers by Sevan Optoelectronics redefine the boundaries of spectral detection with their core advantages of "precision, efficiency, and flexibility". In the wave of the rise of domestic precision instruments, Sevan Optoelectronics will continue to deepen micro-miniaturization and intelligent spectrometry technology, making every ray of light a "smart eye" that empowers innovation, injecting strong power into the high-quality development of various industries.
