The FL-400 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 Call for Price. |
The FL-400 Flame-resistant Fiber Probe consists of a high-temperature 400 µm gold-jacketed UV-VIS optical fiber in an 8-inch-long nickel sleeve. The probe is connected with a splice bushing to a standard SMA-terminated patch cord, which couples to the spectrometer to measure emission spectra.
Spectroscopy Teaching Tool
The FL-400 Flame-resistant Fiber Probe is especially beneficial as an emission spectroscopy teaching tool for use with Ocean Optics'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' CHEM4-series of low-cost, UV-VIS teaching-lab spectrophotometers. Use the probe in two ways:
By introducing it into emission sample environments up to 750° C
By attaching a standard platinum or nickel wire loop at the probe tip so that users can observe flame emission spectra of samples such as sodium, potassium, calcium and copper
Interesting experiments to use in explaining emission measurements.
These specifications apply to the gold-jacketed fiber and nickel sleeve that comprise the probe assembly. The probe connects with a splice bushing to a standard patch cord.
