X-Cite Tetrem XT640L 4-Channel 385nm LED Fluorescence Illuminator with smartDIAL Control

The X-Cite Tetrem XT640L is a programmable 4-channel LED fluorescence illuminator designed for advanced microscopy and live cell imaging applications. Covering excitation wavelengths from 380 to 660 nm, it includes LED peaks at 385, 475, 555, and 635 nm tailored for widely used fluorophores such as DAPI, FITC, mCherry/TRITC, and Cy5. The illuminator supports individual or simultaneous LED operation, optimizing excitation and minimizing bleed-through in multi-band filter setups.

Equipped with the proprietary smartDIAL™ controller, users benefit from intuitive manual control via large tactile buttons, an OLED display showing wavelength and intensity, and rapid LED ON/OFF response times (100 μs TTL, 1 ms USB). Connectivity options include TTL, analog intensity control, RS-232 commands with SDK support, and USB interfaces, making it adaptable for complex microscopy systems and automation workflows.

The compact unit measures 95 x 230 x 212 mm and weighs 3 kg, powered by a universal 24 VDC, 4.0 A external power supply. Certified for CE, RoHS, UKCA, and KC standards, it ensures safety and reliability. LEDs are warranted for 25,000 hours or 3 years, supporting sustained use in biotechnology research fields such as molecular diagnostics, fluorescence analysis, and bioprocessing workflows essential for synthetic biology and biomanufacturing pipelines.

This illuminator is widely used among researchers requiring a cost-effective upgrade from lamp-based systems, offering stable, high-intensity excitation essential in gene editing, live-cell fluorescence imaging, and routine microscopy tasks in biomedical engineering environments.
