Description
This model of single-frequency (SLM) 405 nm lasers is widely used in
compact Raman spectrometers. Small footprint and +5VDC (USB typical)
operating voltage is exactly what's needed for handheld portable
devices. Integrated precision driver electronics
ensure low-noise and very stable operation throughout the wide
temperature range. 405 violet radiation features high energy photons,
therefore much lower power is enough for efficient excitation of
fluorescence or Raman scattering.
Fiber Termination - FC/APC (AT):
8° polishing angle minimizes back reflections from fiber tip. This is necessary especially for SLM lasers.
