Abstract
The utility model relates to an optical fiber coupling device for a fluorospectrophotometer, which is composed of a three-end optical fiber bundle, wherein the three-end optical fiber bundle is combined by an incidence optical fiber and a receiving optical fiber bundle; an optical fiber coupler is fixed on an input end of the incidence optical fiber, and the other end is arranged on the central position of the receiving optical fiber bundle; a fluorescent coupling probe of a linear array end face is used as an output end of the receiving optical fiber bundle and can be fixed on a photometric detecting unit. Considering the adjustable distance between the optical fiber and a detected sample, an adjusting sleeve is additionally arranged on an input end of the receiving optical fiber bundle. The utility model not only can conveniently detect a fluorescence spectrum of a sample which can not be arranged in a sample chamber, but also is suitable for selecting other laser light sources conveniently according to requirements; because the peak power of a laser is much larger than a light source xenon lamp of the fluorospectrophotometer, the detecting accuracy and efficiency can be further increased.
Description
Technical field
The utility model relates to a kind of fiber coupling device that is used for fluorospectrophotometer.
Background technology
Fluorometry since advantages such as highly sensitive, wide dynamic range and high specificity have been widely used at aspects such as material detection, material component analyses.When some material of excitation light irradiation, some material molecule absorbs exciting light, sends the fluorescent radiation of wavelength greater than exciting light, and fluorescence spectrum can reflect the characteristic of fluorescent material.Fluorospectrophotometer with regard to being based on this character of material to its a kind of analytical instrument that carries out qualitative and quantitative analysis.
But because fluorospectrophotometer is highly sensitive, price is also higher relatively, does not also belong to breadboard conventional instrument.The fluorospectrophotometer that uses is based on the medium-to-high grade instrument of external introduction at present.Often need to measure some in actual applications and can't put into the fluorescence spectrum of the sample of sample chamber, for example measure the fluorescence spectrum of human body skin etc.In addition, the light source of existing fluorospectrophotometer mostly is xenon lamp, is not easy to select as required other light sources such as LASER Light Source in practicality.
Summary of the invention
The objective of the invention is to overcome the limitation of existing fluorospectrophotometer in application facet, the function of the existing fluorospectrophotometer of expansion improves its utilization factor, and a kind of fiber coupling device that is used for fluorospectrophotometer is provided.
The fiber coupler 2 of the utility model by comprising lens combination with the light beam coupling of laser instrument 1 output in incident optical 3, with receiving the laser-induced fluorescence (LIF) that fibre bundle 6 is collected sample 4, be coupled to the probe unit 8 of fluorospectrophotometer by fluorescence coupling probe 7.
Therefore, the utility model is by comprising incident optical and receiving the three end fibre bundles that fibre bundle makes up, and the input end of incident optical is fixed with fiber coupler, its other end is on the center that receives fibre bundle, the output terminal that receives fibre bundle is the fluorescence coupling probe of linear array end face, and can be fixed on the photometric probe unit.Consider that the distance between optical fiber and the tested sample is adjustable, install a regulating sleeve additional at the input end that receives fibre bundle.
Utilize this device, not only can measure the fluorescence spectrum of the sample that can't put into the sample chamber easily, and, can further improve accuracy of detection and efficient because the peak power of laser is far longer than the light source xenon lamp of fluorospectrophotometer.
