The XLM Plus LED fiber optic illuminator module with electronics by Excelitas Technologies is suited for endoscopy, surgical microscopy, and surgical headlamp applications. The product provides light output that is comparable to 180 W Xenon sources, yet with the advantages of LED lighting, which include long life, less heat output, and virtually no ultraviolet or infrared radiation, which eliminates the need for filtering.  The XLM Plus LED Light Module is compliant with medical safety standards IEC/EN 60601-1 and EN 60601-1-2, and it includes integrated electronic circuitry for safety alarms, error mode and power status indicators. It provides circuitry for connection to fiber safety interlocks, and it can be immediately shut off for vision protection in the event a fiber is removed from the illuminator during use.  

The XLM Plus operates on 12V DC or 24V DC input. Light intensity can be varied by constant current and/or by an internal or external pulse width modulation (PWM) signal.  PWM enables users to control light output while maintaining a stable correlated color temperature.  In addition, the Module’s RS-232 and auxiliary interfaces allow users to control the light source from a remote location and easily interface the light source with camera systems.  Other product features include integrated thermal monitoring, variable speed fan, and over-temp protection.  These features increase patient safety and aid in ensuring a long operational life, upon integration into a medical OEM’s finished device.
