Market Overview
The global market for Fully Automatic COS Testers was valued at US$ 99 million in 2025 and is projected to reach US$ 194 million by 2032, growing at a CAGR of 10.3%. In 2024, the production volume was 2,327 units, with an average price of USD 38,500 per unit and a gross margin of 36.1%. Each production line supports an annual capacity of approximately 150 units, highlighting the capital-intensive, low-volume nature of this high-tech equipment.

Fully Automatic COS Testers are integrated characterization systems designed to measure and evaluate post-packaged COS semiconductor laser chips with exceptional precision. Equipped with temperature-controlled workstations, these systems automatically capture optical power, voltage, current, wavelength, far-field divergence, and polarization, while performing chip facet defect inspections. Advanced automation features, such as OCR-based chip ID recognition, dual-station parallel testing, and automatic bin sorting, optimize throughput, ensuring high efficiency and reliability in chip performance testing, reliability assessment, and R&D.
