89 North LDI-R-G-WF Red/Green Laser Diode Illuminator for Fluorescence Microscopy

The 89 North LDI-R-G-WF is a _solid-state red/green laser diode illuminator_ engineered for advanced fluorescence microscopy applications. It delivers dual-wavelength light output at 555 nm (green) and 640 nm (red) using laser diodes, providing up to 1000 mW total output power. This bench-top light source unit integrates a 3mm liquid light guide for efficient fiber optic coupling to microscope illumination paths, supporting a wide range of imaging instruments with compatible collimating adapters.

Key technical features include:

• _Independent shutter control_ and _intensity modulation_ for each of the two laser channels via Micro-Manager or proprietary LDI GUI software, ensuring precise illumination in multi-channel fluorescence experiments.
• Wavelength range specifications: 553–555 nm (green), 632–643 nm (red), ideal for excitation of common fluorescent probes used in _biotechnology_, _cell imaging_, and _molecular diagnostics_.
• Solid-state laser diodes offering stable, coherent light output with rapid on/off switching capabilities suitable for _photostimulation_ and _live-cell imaging_ workflows.
• Robust _3mm light guide_ connection facilitating integration with confocal microscopy and widefield fluorescence setups.
• The unit supports applications in _confocal microscopy_, _multi-channel fluorescence imaging_, _live-cell imaging_, and _photostimulation experiments_, making it critical equipment in _biopharmaceutical research_, _synthetic biology_, and _bioprocessing_ laboratories.

This illuminator is widely adopted in research involving _fluorescence excitation_ in neuroscience imaging, cellular dynamics studies, and gene editing visualization. Its compatibility with major microscope brands and reliable performance make it suitable for biomanufacturing labs focusing on precise fluorescence analysis.
