"Long laboratory testing cycles, difficult to trace the source of sudden on-site pollution", "Lagging component sampling inspection on industrial production lines, loss of millions of defective products due to leakage", "Scientific research experiments require precise capture of transient spectra, slow equipment response leads to missed key data" - In fields such as environmental monitoring, industrial manufacturing, biomedicine, and cutting-edge scientific research, The pain points of traditional spectral analysis equipment, such as "large size, slow response, poor adaptability and complex operation", are becoming the core bottlenecks restricting efficiency improvement and innovation breakthroughs.
As a national high-tech enterprise deeply engaged in the optoelectronic field for over two decades, Saifan Optoelectronics accurately perceiving industry demands and, relying on its independently developed core technologies in optical design and signal processing, has launched the 7IGF series of micro fiber optic spectrometers. This series of products takes "micro portable body +0.1nm high-precision detection + millisecond-level response speed" as its core competitiveness, integrating the advantages of horizontal cross optical path design and imported core components, perfectly covering the full range of scene demands from precise laboratory analysis to rapid on-site detection. Today, the 7IGF series has become the trusted choice of over 2,000 research institutions and enterprises, providing precise empowerment in fields such as perovskite research, semiconductor testing, and environmental traceability, with a customer repurchase rate as high as 45%.
I. Scientific Research Exploration: Accurately capture transient signals to facilitate breakthroughs in top-tier journal achievements
Professor Li from the School of Materials Science and Engineering of a 985 university has repeatedly encountered obstacles in the research on the stability of perovskite solar cells: "We need to monitor the dynamic changes of the pholuminescence spectrum in real time and capture transient signals at the millisecond level. However, traditional spectrometers are large in size and slow in response. They not only cannot be adapted to the precision optical platform in the laboratory but also often miss key spectral fluctuation data." What's even more troublesome is that some experiments need to be carried out in inert gas glove boxes, and the bulky equipment simply cannot fit in.
The "miniaturization + high precision" feature of the Saifan 7IGF series fiber optic spectrometer has completely solved the pain points in scientific research. This series adopts a horizontal cross optical path design, with a fixed grating that does not scan. It features a compact and exquisite structure, with a body size of only 147mm×124mm×58mm and a weight of just 1Kg. It can be easily embedded in narrow Spaces such as glove boxes and clean benches. Equipped with an imported back-sensing CCD chip and a 3600-line /mm high-resolution grating, the resolution can reach 0.5nm (with a slit width of 10μm) within the wavelength range of 380-1000nm, and the wavelength repeatability is precise to 0.1nm. It can clearly capture the weak signals and subtle fluctuations of the fluorescence spectrum. What's more worth mentioning is that its exposure time can be flexibly adjusted between 1ms and 7s. Coupled with an ultra-high signal-to-noise ratio of ≥60dB and a millisecond-level response speed, transient spectral signals have no place to hide.
With the 7IGF spectrometer, our experimental efficiency has increased by three times! Professor Li excitedly shared, "It successfully captured the transient attenuation signal of photoluminescence in perovskite materials, providing us with key data support for optimizing the material formula. Last year alone, it produced three SCI top journal papers." Moreover, the equipment is easy to operate. The accompanying spectral calibration software and application software are easy to use. After a brief training, postgraduate students can operate it independently, which greatly lowers the threshold for scientific research. In response to the diverse demands of scientific research, the 7IGF series also supports customizing multiple slit widths ranging from 10 to 1000μm. It can flexibly adjust the luminous flux and resolution according to experimental requirements, making it suitable for cutting-edge research scenarios such as Raman spectroscopy and plasma diagnosis.
Ii. Industrial Quality Control: Online real-time detection to build a solid quality defense line
Wang, the production line manager of a leading semiconductor company, was once troubled by the problem of wafer coating thickness detection: "The traditional offline detection mode requires sampling and sending it to the laboratory for analysis, with a detection cycle of up to two hours. Once the coating thickness is found to be substandard, the entire batch of products has to be reworked, resulting in a single loss of over 500,000 yuan." Moreover, sampling and testing are subject to randomness and cannot achieve full-process quality control. The risk of defective products flowing out always exists.
The practical application of the 7IGF series of industrial online models has achieved "cost reduction and efficiency improvement" in quality control. This model is designed with an IP65 protection level, featuring extremely strong anti-vibration and anti-interference capabilities. It can be directly embedded in the production line to achieve 24-hour continuous monitoring. Through the SMA905 standard optical fiber interface, the instrument can achieve non-contact detection without damaging the sample. It can collect spectral data in real time during the wafer coating process and complete thickness analysis within one minute, with a detection error of ≤0.03%, which is 120 times more efficient than the traditional mode. Equipped with a USB2.0 high-speed data interface, the detection data can be transmitted in real time to the MES industrial system, achieving full-process automation of "detection - analysis - early warning", and avoiding the risk of defective products from the source.
Since the introduction of the 7IGF spectrometer on the production line, our defective product rate has dropped from 1.2% to below 0.03%, reducing losses by over 6 million yuan annually. Engineer Wang stated, "The stability of the equipment exceeded expectations. It operated continuously for 24 hours without failure, and the stray light level was as low as 1×10⁻³, ensuring the consistency and reliability of the detection data." Moreover, the technical team of Saifan has customized a multi-channel synchronous acquisition solution for us, enabling simultaneous detection at multiple workstations and further increasing production capacity by 15%." In addition to the semiconductor field, the 7IGF series is also widely used in scenarios such as chromaticity detection of LED light sources and composition analysis of welding points in new energy vehicle batteries, becoming the "quality gatekeepers" for the intelligent transformation of industry.
Iii. Environmental Monitoring: Portable Mobile Traceability, Safeguarding Ecological Security
Engineer Zhang from a provincial environmental monitoring station deeply realized the limitations of traditional equipment during the task of tracing the source of sudden water pollution in the field: "After a sudden water pollution incident occurs, we need to determine the composition of pollutants immediately. However, traditional spectrometers are large in size and rely on fixed power supplies, making them impossible to carry to the field site." By the time the water samples were brought back to the laboratory for analysis, the contamination had already spread, and the best opportunity for disposal had been missed.
The "lightweight + long battery life" advantages of the 7IGF series portable spectrometers provide a brand-new solution for on-site monitoring. This model weighs only 1Kg and is equipped with a built-in lithium battery. When fully charged, it can work continuously for 8 hours, fully meeting the requirements of mobile field detection. The instrument supports multiple spectral measurement modes such as transmission, absorption and fluorescence, and can quickly identify heavy metals, organic substances and other pollutant components in water. Combined with the preset pollutant spectral library, traceability analysis can be completed within 10 minutes, providing precise data support for emergency response. During a sudden pollution incident in a river, the monitoring team rushed to the scene with a 7IGF spectrometer and identified the pollutant as a phenolic substance in just 30 minutes, thus buying precious time for the formulation of the subsequent disposal plan.
"7IGF is our 'mobile laboratory' for environmental monitoring!" " Engineer Zhang praised, "It is not only portable and easy to use, but also its detection accuracy is no less than that of large-scale laboratory equipment. In multiple comparison experiments, the consistency of its data with the detection results of the national standard method is as high as over 98%." Nowadays, whether it is the monitoring of outdoor water bodies and the atmosphere, or the on-site verification of enterprise sewage outlets, we cannot do without it, which has greatly enhanced the efficiency and accuracy of environmental supervision."
