For professionals in fields such as materials development and on-site testing, fluorescence-based qualitative and quantitative analysis has traditionally required transporting samples between laboratories—often resulting in wait times of several hours or even days for results—and relying exclusively on operators with specialized qualifications. Moreover, benchtop instruments costing hundreds of thousands of RMB have long been prohibitive for many small- to medium-sized research groups and grassroots testing institutions.

At its core, this type of detection hinges on capturing the characteristic fluorescent emission spectra generated when a substance is optically excited. Each material exhibits a unique “optical fingerprint” defined by its fluorescence peak positions, intensities, and quantum efficiency. Accurately capturing these spectral signatures enables rapid determination of a target substance’s concentration, physicochemical properties, and optical performance. Historically, however, portable fluorescence detectors struggled to balance miniaturization with measurement accuracy—largely due to limitations in optical module integration and calibration technology—making them ill-suited for professional-grade applications.

To address the industry’s longstanding dilemma—“portability versus precision cannot coexist”—Jingyi Optoelectronics has developed a fully self-designed Fluorescence Quantum Efficiency Analyzer. From optical modules and calibration systems to software interfaces, every component in the entire workflow has undergone end-to-end optimization. Leveraging a traceable standard light source for full-chain calibration and Jingyi’s proprietary signal correction algorithms, the instrument not only performs routine qualitative and quantitative screening but also delivers precise measurements of quantum yield, chromaticity parameters, and complete photoluminescence (PL) spectra—automatically recorded in full resolution. Compatible with solutions, powders, and thin-film samples alike, it supports diverse application scenarios spanning fundamental research to industrial quality control.

Compared with conventional benchtop fluorescence spectrometers—often standing half a person tall—the Fluorescence Quantum Efficiency Analyzer achieves ultra-high integration of its core optical modules. Its overall footprint is just one-fifth that of comparable benchtop systems, and its lightweight design allows single-person portability—fully meeting the mobility requirements of on-site testing. Operationally, aside from manual tasks such as swapping light sources and loading/unloading samples, all other measurement steps are executed with a single click via the proprietary software platform. This software was specifically designed by Jingyi Optoelectronics for non-specialist users: it eliminates complex parameter settings and instead organizes all functions into intuitive, modular workflows. Upon completion, it automatically generates standardized test reports. Even personnel without prior expertise in spectroscopic analysis can operate the system independently after only 10 minutes of basic training—effectively eliminating dependence on highly trained specialists. A full measurement cycle takes just 15 minutes, delivering results up to dozens of times faster than traditional lab-based methods. Real-time output empowers users to make timely decisions and prevent issue escalation.

In practical deployment, the value of this Fluorescence Quantum Efficiency Analyzer has already been validated across multiple domains:  
- University materials research groups carry it directly to pilot-scale facilities to measure the quantum efficiency of novel fluorescent materials on-site—eliminating the need for repeated lab-based testing and boosting R&D efficiency by at least threefold;  
- Grassroots environmental monitoring stations deploy it at riversides and industrial parks to rapidly detect heavy metals, formaldehyde, and polycyclic aromatic hydrocarbons (PAHs) in water and air—achieving accuracy compliant with national standards and fully supporting both emergency response and routine inspection;  
- In food safety rapid-testing contexts, it enables swift quantification of pesticide residues and illegal additives—providing an efficient tool for food safety spot checks throughout supply chains;  
- Even in primary healthcare settings, it supports semi-quantitative detection of tumor biomarkers and blood glucose levels—delivering accessible technical support for rural medical outreach programs and community health screenings.

With years of deep expertise in optical metrology, Jingyi Optoelectronics has not only resolved the trade-off between portability and precision but also reduced the total acquisition cost to approximately one-third that of conventional benchtop fluorescence spectrometers—significantly lowering entry barriers for small- and medium-sized research teams and grassroots testing institutions. High-precision fluorescence analysis is no longer the exclusive domain of large-scale laboratories. As demand for on-site testing continues to surge, fluorescence detection instruments combining high accuracy, portability, and exceptional cost-performance ratios will become indispensable tools across scientific research, environmental protection, food safety, and healthcare—accelerating the broader testing industry’s evolution toward “lightweight, inclusive, and intelligent” solutions.
