Embodiment 1

[0011] Example 1 Combined figure 1 The configuration of the present invention will be described. figure 1 Among them, 1 is the hollow fiber, 2 is the electrode, 3 is the cover of the head, 4 is the hollow spherical part of the head, 5 is the glass window, 6 is the sample injection tube, and 7 is the potting material such as indium and tin. The head cover 3 includes a glass tube and a hollow spherical part 4 in the middle. One end of the glass tube is sealed by a glass window 5. After the other end is inserted into the hollow optical fiber 1, it is poured into the glass with potting materials 7 such as indium and tin. Seal between the tube and the hollow fiber 1. The end of the hollow fiber 1 is close to the glass window 5 . The sample injection tube 6 is installed on the hollow spherical part 4, and can be perpendicular to the glass tube of the head jacket 3. Half of the electrode 2 is inserted into the hollow spherical part 4, and the other half is exposed outside the holl...

Embodiment 2

[0014] Example 2 An example is given—measuring the influence of temperature on the intensity of fluorescence spectrum.

[0015] The liquid sample consists of pyridine, potassium sulfate and distilled water, and is filled into the device of the present invention to form a liquid-core optical fiber with a length of 123 cm. At this time, the refractive index of the liquid sample is 1.50, and the refractive index of the optical fiber is 1.46. The optical fiber is packed with heat-insulating material. Two thermocouples are used to measure the temperature of the liquid sample in the optical fiber and the outside temperature. One end of the optical fiber is incident with a He-Ne laser. The multiplier tube receives the fluorescent signal, and the spectral intensity (photon number) is received by a photon counter. The two electrodes are connected to a DC high-voltage power supply, and the current is stable for a period of time. After the temperature measured by the two thermocouples i...

Abstract

The spectrum measuring apparatus for optic fiber in electric field of the present invention is a spectrum measuring apparatus for optic fiber. The structure is that there is an optic fiber sealer on each end of the hollow optic fiber (1) with the sealer housing (3) of the sealer of the optic fiber having the shape of a glass pipe with hollow ball (4) in its center. On one end of the glass pipe is a glass window (5), the other end is sealed with encapsulating materials (7) such as indium and tin after inserted with a hollow optic fiber (1). The electrode (2) and sample filling pipe (6) are mounted on the glass ball of the sealer housing (3). The present invention can be used as a sample chamber for spectrometer with a high sensitivity and ready replacement of sample.

Description
