X-Cite TETREM 4-Channel LED Illumination System
Compact 4-channel LED system for advanced fluorescence microscopy illumination
The X‑Cite TETREM 4‑Channel LED Illumination System from Excelitas is a compact, high-performance LED light source engineered for fluorescence microscopy. It features four independently controllable LED channels tuned to excite commonly used fluorophores (DAPI, FITC, TRITC/mCherry, Cy5) and is available in models with either 365 nm or 385 nm UV excitation. With fast microsecond switching, analog/TTL/USB control and a sleeker user interface (smartDIAL), it offers a cost-effective upgrade path from traditional lamp-based systems for routine imaging workflows.
