Lumencor SPECTRA Light Engine 4-API-LB Multi-Wavelength Solid-State Fluorescence Illumination Unit

The Lumencor SPECTRA Light Engine 4-API-LB is a compact, high-performance solid-state fluorescence illumination unit engineered for advanced microscopy applications including live-cell imaging, optogenetics, and molecular diagnostics. Featuring *four integrated LED spectral bands* (blue, cyan, yellow, teal) plus a GRN/YEL excitation filter, it delivers a total optical power of 269 mW with a field uniformity of less than 5% peak to peak and exceptional stability below 2% peak to peak.

Key Technical Specifications and Features:

• Spectral bands: Four integrally installed bandpass filters spanning from blue to yellow wavelengths, optimized for multicolor fluorescence excitation.
• Switching speed: Up to 5 kHz with on/off transition times approximately 10 μsec, enabling rapid sequential excitation essential for high-content screening and multicolor fluorescence assays.
• Output adaptability: Compatible with Köhler, critical, direct, and light guide outputs (adapter not included), allowing flexible integration with various microscopy systems.
• Control interfaces: Trigger via TTL or RS232 protocols for precise synchronization with imaging acquisition hardware, critical in workflows such as gated fluorescence and optogenetic stimulation.
• Compact dimensions: Measuring 9 x 18 x 23 cm and weighing 3.6 kg, designed for seamless integration into existing microscope setups without compromising spatial constraints.

Applications: This light engine is widely used in fluorescence microscopy, live-cell and high-content imaging, flow cytometry excitation, and digital pathology illumination, offering a reliable and energy-efficient alternative to traditional broadband lamps. It is critical in biotechnology research domains such as molecular diagnostics, synthetic biology, and bioprocessing, providing precise, stable excitation light to support complex gene editing and cellular phenotyping workflows.

Additional Support: The unit is fully serviced, tested for spectral output consistency, thermal stability, and mechanical integrity, backed by a warranty suitable for academic, clinical, and biopharmaceutical laboratories. Integration support and technical consultation are available to optimize use in diverse fluorescence microscopy configurations.

This makes the Lumencor SPECTRA Light Engine a robust, essential component for researchers requiring rapid wavelength switching and stable, high-intensity excitation sources in advanced bioimaging and biotechnology applications.
