Follow on Google News | New 5W-100W Square Light Spot Laser Solutions for Photovoltaic Cell InspectionLumispot Tech has successfully engineered a laser system capable of delivering large field-of-view, high uniformity, and high brightness for sustained operations.
By: Lumispot Tech Application Scenarios of the Square Light Spot Laser This product line represents Lumispot Tech's independently developed square-spot system, utilizing fiber-coupled semiconductor lasers as the light source. Incorporating high-precision control circuits and conveying the laser through optical fibers into an optical lens, it achieves a square-spot laser output at a fixed divergence angle. Primarily, these products are tailored for the inspection of photovoltaic (PV) cell panels, specifically in the detection of light and dark cells. During the final inspection of cell panel assemblies, Electro-Luminescence (EL) electrical testing and Photo-Luminescence (PL) optical testing are conducted to grade the assemblies based on their luminous efficiency. Traditional linear PL methods fall short in differentiating between light and dark cells. However, with the square-spot system, a non-contact, efficient, and synchronous PL inspection of different areas within the cell assembly is possible. By analyzing the imaged panels, this system facilitates the distinction and selection of light and dark cells, thereby preventing the downgrade of products due to the low luminous efficiency of individual silicon cells. Product Features Performance Characteristics 1. Selectable Performance and High Reliability: 2. Multiple Control Modes: Offering three control modes, the laser system allows customers to tailor control based on situational needs. 3. High Spot Uniformity: The system ensures stable brightness and high uniformity in its square-spot output, aiding in the identification and selection of anomalous cells.
