The X-Cite 120Q is a high-performance fluorescence illumination system developed by Excelitas Technologies, specifically engineered for fluorescence microscopy applications in biological research, biomedical studies, clinical diagnostics, and shared laboratory facilities.
The system delivers broad-spectrum, stable, and highly uniform excitation light, ensuring reliable performance for routine fluorescence assays while maintaining optimized operating costs.
Extended Lamp Life – Intelli-Lamp Technology
At the core of the X-Cite 120Q is the proprietary Intelli-Lamp technology, which continuously maintains the lamp at its optimal operating temperature throughout use. As a result, the system offers a 2000-hour lamp warranty with a typical operational life exceeding 2500 hours, significantly outperforming conventional mercury lamps. This extended lifetime minimizes lamp replacement frequency, reduces downtime, and lowers long-term operating costs.
The 120 W Mercury Vapor Short Arc lamp is factory pre-aligned, allowing for a fast, single-step lamp replacement without optical realignment, ensuring consistent illumination performance over time.
Precise Intensity Control – Reduced Photobleaching
The X-Cite 120Q features a 5-position mechanical iris (100%, 50%, 25%, 12%, 0%), enabling precise control of illumination intensity for different specimens and fluorophores. Accurate light level adjustment helps minimize photobleaching, extend observation time, and improve accuracy in fluorescence imaging and quantitative analysis.
Heat and Vibration Isolation – Protection for Microscope and Samples
The system connects to the microscope via a liquid light guide (3 mm × 3000 mm), allowing the light source to be positioned remotely from the microscope. This design ensures no heat or vibration is transferred to the optical system, protecting sensitive samples, improving image stability, and optimizing valuable laboratory workspace.
Hot-Strike Prevention – Preserving Lamp Performance
Hot-strike events—restarting the lamp while it is still hot—can significantly shorten lamp life and degrade output intensity. The Intelli-Lamp system continuously monitors lamp temperature, preventing re-ignition until a safe-to-restart condition is reached. This feature protects the lamp and ensures consistent, long-term illumination performance.
Optimized Optical Adapters for Each Microscope
X-Cite optical adapters are specifically designed and tested for inpidual microscope models to maximize light throughput and deliver superior illumination uniformity across the field of view. The X-Cite 120Q is compatible with major microscope brands, including Nikon, Leica, Zeiss, Olympus, and Motic.
When ordering, users simply provide their microscope model to receive the appropriate adapter configuration.
Safety and International Compliance
The X-Cite 120Q is designed with operator safety as a priority, incorporating safety interlock switches and light shielding to reduce the risk of accidental exposure to UV or high-intensity visible light. The system operates on a universal 90–264 VAC power input, is CE marked, and complies with IEC, Canadian, and U.S. laboratory equipment safety standards.
Environmental Responsibility and Sustainability
The mercury (Hg) lamp used in the X-Cite 120Q contains mercury and must be handled and disposed of in accordance with local environmental regulations. Users are advised to follow applicable waste management laws and refer to lamprecycle.org or contact the supplier for proper disposal guidance.
