ZFA-V-405 – Diode Laser at 405 nm
The ZFA-V-405 is a high-stability 405 nm CW diode laser featuring long coherence length (>1 m), stable wavelength performance, and extended operational lifetime. Designed for precision optical applications, it provides a near TEM00 beam profile, low divergence (<1.5 mrad), and high polarization ratio (>50:1, optional >100:1). Compact, reliable, and easy to operate, the ZFA-V-405 is ideal for demanding applications such as holography, interferometry, fluorescence analysis, photolithography, flow cytometry, DNA sequencing, Raman spectroscopy, LIDAR, and precision metrology. With excellent power stability (<1–3% RMS over 4 hours), fast warm-up (<5 minutes), and a 10,000-hour lifetime, this laser ensures consistent performance in laboratory, industrial, and OEM environments.
