U-FLLED LED Illumination System
Modular LED light sources for everyday fluorescence microscopy.
The U-FLLED solid-state LED illumination system is designed to make fluorescence light sources easy to add, simple to use, and ready to grow with evolving experimental needs. A complete LED solution for conventional upright and inverted microscopes, the system combines a modular design, intuitive control, and long-term stable illumination for routine fluorescence workflows.
U-FLLED LED Illumination System
Fluorescence Illumination, Purpose-Built for Conventional Microscopes
The U-FLLED solid-state illumination system is engineered to seamlessly integrate with Evident conventional upright and inverted microscopes, empowering laboratories to add or upgrade their fluorescence light source capabilities and scale their work as needs evolve with a complete 2–4 color LED illumination solution.
Its direct-mount design preserves familiar microscope operation, while a modular architecture enables you to start with essential excitation channels and expand over time. Passive, fan-free cooling ensures silent, vibration-free performance at the microscope, making it ideal for everyday use.
- Direct integration with conventional microscopes
- Blue and green LED light source with upgradable UV and deep red channels
- Silent, vibration-free operation
