ZFA-V-785 diode laser
The ZFA-V-785 diode laser delivers a stable 785 nm output with long coherence length (>1 m) and near TEM00 beam quality.
It operates in CW mode with output power up to 50 mW and excellent power stability (<1% RMS). Compact and user-friendly, it ensures fast warm-up (<5 min) and extended lifetime (10,000 hours). Low beam divergence (<1.5 mrad) and high polarization ratio (>10:1) support precision optical experiments. Ideal for research, industrial, and OEM applications requiring reliable, stable laser sources.
Supports horizontal or vertical polarization orientation with optional high polarization ratio. Robust design operates in 20–30°C environment with standard 100–240 VAC power supply.
