The combined light source comprises a tungsten halogen lamp, a silicon carbide rod, a movable small platform, a guide track, a reflective and a lens; the combined light source can achieve the light source conversion that the light path of the light source is not changed by moving the movable small platform arranged on the guide track; simultaneously, the movable small platform is locked by magnetic force, the light path of the light source has high stability and high reliability. When an imaging spectrograph requires spectrum calibration within a spectrum range or an infrared spectrum range, the spectrum calibration can be achieved by moving the movable small platform.
Description
Technical field
The utility model relates to the light source of monochromator, specifically be meant monochromator incident light source can visible and infrared between the mutual combined light source of conversion.
Background technology
In the spectral calibration of imaging spectrometer, monochromator is to obtain the monochromatic key equipment of high-purity.Imaging spectrometer has very wide spectral range usually, its spectral range can infrared from seeing (0.4～13 μ m), so require monochromator also can export the monochromatic light of corresponding light spectral limit continuously, this has the spectral range of broad with regard to the incident light source that needs monochromator.Usually certain light source only has stronger radiation in certain spectral range, and for example the spectral range of Chang Yong halogen tungsten lamp is 0.4～2.5 μ m, and and for example the spectral range of Chang Yong Elema is 0.7～20 μ m.This shows that will satisfy the spectral calibration requirement of imaging spectrometer, a kind of light source is difficult to finish, and is two or more usually.For addressing this problem, way in the past is that existing usefulness is now changed light source, and such way wastes time and energy, and particularly when needs are calibrated repeatedly, because the optical path states instability, it is not enough to cause calibrating repeatable accuracy.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, the combined light source that can switch mutually easily between visible and infrared two light sources.
The purpose of this utility model is achieved in that combined light source comprises substrate 1, two parallel guide rails 8 are arranged on the substrate, two of guide rail respectively have a locating device 10, the one movable chain-wales 9 that can move on guide rail is arranged on the guide rail, the plane mirror 3 and the positive lens 2 that the reflected light of spherical reflector 4 can be turned to the monochromator slit are arranged on the chain-wales, also have spherical reflector 4, visible light source 5 and infrared light supply 6 on the substrate.
The light beam of visible light source 5 outgoing converges on the monochromator slit at two times of focal length places of positive lens through positive lens 2 transmissions.
The light beam of infrared light supply 6 outgoing turns on the slit that converges at monochromator through plane mirror 3 reflections through spherical reflector 4 reflections again.
The utility model has the advantages that:
1. when the imaging spectrometer needs the spectral calibration of limit of visible spectrum, as long as move movable chain-wales, just visible light source can be converged at the slit of monochromator, the monochromatic light of being exported limit of visible spectrum by monochromator carries out spectral calibration.And when needing the spectral calibration of infrared range of spectrum,, infrared light supply is converged at the slit of monochromator as long as movable chain-wales is moved in the opposite direction, just can carry out the calibration of infrared spectrum.
2. move the conversion that realizes light source by movable chain-wales at guide rail, simultaneously movable chain-wales adopts the magnetic force locking, light source light path good stability, and the reliability height can be used for high-precision spectral calibration.
Description of drawings
Fig. 1 is a visible light source working state figure of the present utility model;
Fig. 2 is infrared source working constitutional diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
See Fig. 1, Fig. 2, whole combined light source is to be fixed on the planarizing substrate 1 of aluminum, and visible light source 5 is a halogen tungsten lamp, and positive lens 2 is a glass lens.Infrared light supply 6 is an Elema, and spherical reflector 4 is the standard sphere, and spherical reflector 4 and plane mirror 3 are the glass basis reflectance coating of aluminizing.
At first movable chain-wales 9 is shifted to guide rail 8 on one side, and with locating device 10 locking, regulate visible light source 5 and positive lens 2, make visible light source be positioned at two times of focal length places of positive lens, and the light beam that visible light source is exported converges at the slit 7 of monochromator through the positive lens transmission.
Then movable chain-wales 9 is shifted to the another side of guide rail 8, and with locating device 10 locking, regulate infrared light supply 6, spherical reflector 4 and plane mirror 3, and infrared light supply is positioned on the object point of spherical reflector, through the spheric reflection mirror reflection, turn to the slit that converges at monochromator through the plane reflection mirror reflection by the light beam of infrared light supply output again.Each parts adjustment finishes, and when needs carry out the spectral calibration of limit of visible spectrum, as long as move movable chain-wales, makes on the light path between positive lens immigration visible light source and the monochromator slit, can carry out the limit of visible spectrum calibration of imaging spectrometer.When needs carry out the spectral calibration of infrared range of spectrum, as long as movable chain-wales is moved in the opposite direction, the catoptron on the chain-wales is moved on the light path of spherical reflector and monochromator slit, can carry out the calibration of the infrared range of spectrum of imaging spectrometer.
The shared current regulator power supply of halogen tungsten lamp and Elema just can be realized switching with a change-over switch.
Guide rail and movable platform are made by metal material, and locating device is made by permanent magnetic material.
