Precision Light Engines for Medical Bio-Optics & Diagnostics

Queendom designs and manufactures high-reliability LED light engines and optical components for demanding applications in molecular diagnostics, biomedical imaging, and life science research. Our solutions are engineered to meet the stringent requirements of real-time PCR (qPCR/dPCR), fluorescence microscopy, flow cytometry, and optical coherence tomography (OCT).

Key technical advantages:
Wavelength accuracy: ±2nm tolerance (e.g., 470nm, 525nm, 620nm for FAM/HEX/Cy5)
Thermal stability: Low thermal drift with integrated heat sink (thermal resistance < 5°C/W)
Long-term reliability: L70 > 25,000 hours under continuous operation
Compliance: RoHS, REACH, and manufactured under ISO 13485 quality system
All UV LEDs (e.g., 365nm, 385nm) are intended for fluorescence excitation only and are not designed or certified for germicidal or disinfection use.
