Raman Laser.  Highly stabilized lab laser with adjustable power level, safety interlock and safety googles. Ocean Optics offers high power lasers for Raman excitation wavelengths of 532, 638, 785 and 1064 nm. These multimode diode lasers produce narrow spectral lines, have integrated laser drivers and are thermoelectrically cooled for optimum performance. Options are available with adjustable output power and with SMA 905 or FC fiber connections.

Fiber Optic Raman Probe.  Built in filters and focussing optics for sampling through vials or on solid surfaces
