Footnotes:
- Due to our continuous product improvement program, specifications may change without notice.
- Vanguard One is a Class IV - High-Power Laser, whose beam is, by definition, a safety and fire hazard. Take precautions to prevent exposure to the direct and reflected beams. Diffuse as well as specular reflections can cause severe skin or eye damage.
Features
Designed for 24/7 LHS Applications
The new laser operates air-cooled with low noise of <1% rms and delivers a long-operating life and low cost of ownership. Vanguard One is ideal for applications in bio-instrumentation, including flow cytometry, microscopy, cell sorting, and semiconductor wafer inspection.
OEM Integration
The quasi-CW operation ensures high fluorescence signal-to-noise ratio while preventing cell damage in bio-instrumentation. The laser firmware enables closed-loop power control, ensuring long-term stability with less than 2% power variation for consistent measurement results.
All-In-One Design
Based on the highly successful Vanguard laser family,Vanguard One UV125 is an all-in-one laser,combining electronics, laser cavity, and cooling in a single housing for easy integration and bench-top tools.
Reliability
Vanguard One lasers pass extensive environmental qualification testing to deliver high reliability and low cost-of-ownership needed for bio-instrumentation and demanding industrial applications.
