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

Broad Spectral Coverage for Everyday Fluorophores

The U-FLLED system is optimized for excitation wavelengths commonly used in fluorescence microscopy. The main module includes blue and green LEDs, ideal for fluorophores like Cy2, GFP, and Texas Red. Optional UV and deep red modules support dyes such as DAPI, Hoechst, Cy5, and Alexa 680.

This solution offers practical capabilities for everyday fluorescence imaging without unnecessary complexity.

Simple Controls That Fit How You Work

The U-FLLED system is designed for immediate use with simple controls. An intuitive hand controller offers PC-free operation for routine fluorescence observation, including individual channel selection and intensity adjustment.

For more structured imaging, the U-FLLED system integrates with cellSens™ imaging software, enabling software-based channel control synchronized with image acquisition.

• PC-free operation with a hand controller
• Integration with cellSens imaging software
• Individual channel selection and intensity control or all channel intensity control

Stable Performance Built for Long-Term Use

The U-FLLED system delivers stable uniform illumination using solid-state LEDs rated for about 25,000 hours of operation. Instant on/off performance, a mercury-free design, and a long lifetime reduce maintenance, minimize downtime, and lower total cost of ownership compared to traditional bulb-based illumination.
