The FC904L Fluorescence Multi-LED Illuminator is a high-performance light source designed for advanced microscopy applications where stability and space efficiency are paramount. Utilizing a Remote Light Source Design with Liquid Light Guide Coupling, the FC904L allows the main unit to be placed away from the microscope. This configuration ensures Vibration-Free Illumination, isolating mechanical interference for more reliable and consistent imaging conditions.
The system delivers Four LED peaks across the visible spectrum (385nm, 470nm, 555nm, and 630nm), providing bright and uniform excitation for a variety of fluorophores. Each of the four independent channels includes dedicated filter positions for precise spectral control.
Engineered for flexibility, the FC904L supports PC Control via USB and sophisticated External TTL trigger integration (featuring four individual channel triggers and one global trigger). For real-time manual adjustments, a dedicated Control Pod is included to manage intensity and wavelength selection effortlessly.
