Overview
THIS PRODUCT IS DISCONTINUED. It has been replaced with the X-Cite XYLIS II. Technical support for this product will continue to be available.

Summary
Excelitas offers the X-Cite XYLIS as a laboratory-grade, broad-spectrum LED illumination solution for fluorescence microscopy. Designed for fast switching and multi-peak excitation, the unit supports research and clinical imaging workflows requiring repeatable, TTL- or USB-controlled light delivery. The system provides selectable LED peaks, rapid TTL/USB response times and multiple control interfaces for integration with microscopes and imaging systems.
