Background technique
Fiber spectrometer be it is a kind of using optical fiber as signal coupling device, will be tested by optical fiber optically coupling to spectrometer Middle carry out spectrum analysis.Fiber spectrometer be widely used in gemstone testing, LED measurement, color measuring, water quality monitoring, etc. skills Art field.
With the raising of production technology level, occur a large amount of domestic fiber spectrometers on the market.Currently, market glazing What spectrometer mostly used is CCD array, and the larger fluctuation of temperature will lead to the micro-optical machine built in spectrometer in fiber spectrometer Some devices occur thermal deformation and lead to focus inaccurate, light offset in tool system, and then influence the essence of measurement result True property.Therefore, the temperature in spectrometer should control the error for reducing measurement in a certain range.Meanwhile the prior art Refrigerant is commonly used to adjust the temperature in spectrometer, realizes Process of absorption or liberation of heat by the phase transformation of medium, this way not only exchanges heat effect Rate is lower, and is difficult to effectively monitor to the variation of internal temperature, control.Therefore need to provide a kind of novel optical fiber spectrometer solution The defect of the prior art.
Utility model content
To overcome the shortcomings of existing technologies, the utility model provides one kind to be able to maintain spectrometer internal temperature constant, surveys The accurate novel optical fiber spectrometer of test result.
A kind of novel optical fiber spectrometer, including shell, fiber optic bundle and setting are narrow in the intracorporal fibre-optical splice of shell, incidence Seam, collimating mirror, dispersion element, condenser and CCD array detector, one end and the intracorporal fibre-optical splice phase of shell of the fiber optic bundle Connection, the other end of the fibre-optical splice are connected with external light source, and the entrance slit is arranged at optical fiber interface, the light The collimated mirror collimation back reflection of the signal light of fine beam transmitting is on dispersion element, and light source is after dispersion element dispersion through condenser Aggregation, is finally incident upon on CCD array detector;It further include temperature sensor, the probe of the temperature sensor is arranged in shell In vivo, constant temperature heating plate, heat storage and controller are equipped in the shell;The temperature sensor, constant temperature heating plate and control Device electrical connection processed.
To further realize the utility model, the dispersion element is grating or prism.
To further realize the utility model, straight line where the collimating mirror and light source is in 45 ° of settings.
To further realize the utility model, built-in power, the temperature sensor, heated at constant temperature are equipped in the shell Plate, heat storage, controller are electrically connected with built-in power.
To further realize the utility model, the heat storage is made of mineral wool, heat insulation felt or polyurethane foam material.
To further realize the utility model, the heat accumulation plate is arranged on the inner sidewall of shell.
The utility model has the beneficial effects that
The fiber spectrometer of the utility model, further includes temperature sensor, be equipped in shell constant temperature heating plate, heat storage, And controller;Controller can set suitable temperature, assign instruction control constant temperature heating plate and heated;When ambient temperature compared with Height then issues controller and instructs when temperature inductor probe detects the temperature of shell beyond certain temperature range, constant temperature Heating plate stops heating;So that the fiber spectrometer of the utility model can be applied to different geographical, Various Seasonal meets not equality of temperature Use demand under the conditions of degree is conducive to keep shell body temperature constant, it is ensured that the accuracy of testing result.Setting stores in shell Hot body can accumulate heat, and cooperation constant temperature heating plate keeps the intracorporal temperature of shell constant.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the fiber spectrometer of the utility model.
Specific embodiment
The concrete mode of the utility model is illustrated with reference to the accompanying drawing, the implementing direction of the utility model is with Fig. 1 Direction be standard.
As shown in Figure 1, a kind of novel optical fiber spectrometer of the utility model, including shell 1, fiber optic bundle 2 and setting exist Fibre-optical splice 3, entrance slit 4, collimating mirror 5, dispersion element 6, condenser 7 and CCD array detector 8 in shell 1, the dispersion Element 6 is grating or prism;One end of fiber optic bundle 2 is connected with the fibre-optical splice 3 in shell 1, the other end of fibre-optical splice 3 with External light source is connected, and entrance slit 4 is arranged at optical fiber interface, and straight line where collimating mirror 5 and light source is in 45 ° of settings.Optical fiber The collimated mirror 5 of the signal light that beam 2 emits collimates back reflection on dispersion element 6, and light source is after 6 dispersion of dispersion element through optically focused Mirror 7 is assembled, and is finally incident upon on CCD array detector 8.
A kind of novel optical fiber spectrometer of the utility model further includes temperature sensor 9, the probe setting of temperature sensor 9 In shell 1, constant temperature heating plate 10, heat storage 11 and controller are equipped in shell 1;Temperature sensor 9, constant temperature heating plate 10, It is electrically connected with the controller.Built-in power, the temperature sensor 9, constant temperature heating plate 10, heat storage 11, control are equipped in shell 1 Device is electrically connected with built-in power.The heat storage 11 is made of mineral wool, heat insulation felt or polyurethane foam material, further, stores Hot plate 11 is arranged on the inner sidewall of shell 1.By the suitable temperature of controller setting, and then controls constant temperature heating plate 10 and added Heat operates, and the heat storage 11 in shell 1 can accumulate heat, and cooperation constant temperature heating plate 10 keeps the temperature in shell 1 constant;When outer Boundary's temperature is higher, when temperature inductor probe detects the temperature of shell 1 beyond certain temperature range, then issues to controller Instruction, constant temperature heating plate 10 stop heating.Temperature is constant in its shell 1 of the novel optical fiber spectrometer of the utility model, not by outer The limitation of boundary's temperature advantageously ensures that the stability of measurement result.
