产品参数
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.
High-temperature Fiber
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.
Specifications
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.
