DS3-11444-K405EMSCN 405nm Semiconductor Laser System
The DS3-11444-K405EMSCN is a 405nm semiconductor laser system from BWT, delivering 50W continuous-wave output power with a center wavelength of 405±5nm and spectral width ≤6nm (FWHM). It features a 400μm fiber core diameter, 0.22 numerical aperture, and pluggable output with an optional SMA905 fiber connector. Powered by DC 24V with constant-current drive, the compact water-cooled system (223×224×63mm³) supports RS232 and I/O control, along with over-current and over-temperature protection, making it a reliable violet laser source for precision applications.
