FL-400 Flame-resistant Fiber Probe
The FL-400 F LAME - RESISTANT F IBER P ROBE is a heat-resistant fiber optic probe that couples to Ocean Optics
miniature fiber optic spectrometers to measure in situ emission spectra of samples such as dissolved metals and
high-temperature plasmas. The FL-400 is a high-temperature 400-
µ m gold-jacketed UV-VIS optical fiber in an
8" long nickel sleeve. It can operate in environments up to 750º C. The probe comes with a standard wire loop for
emission measurements of dissolved metals. Not included, though necessary for operation, is an optical fiber and a
splice bushing for connecting the FL-400 to the optical fiber.
Operation
1. Twist the male end of the FL-400 into a 21-02 Splice Bushing.
2. Connect a standard optical fiber (normally a P400-2-UV/VIS 400
µ
m optical fiber) to the other end of the
splice bushing.
3. To observe flame emission spectra of samples such as sodium, potassium, calcium and copper attach the wire
loop to the FL-400 by slipping the FL400 into the coil spring of the wire loop.
