Abstract
The invention provides a light source enhancing device of an oil emission spectrometer, wherein light emitted by a light source of the oil emission spectrometer is converged at an incident slit of a light splitting unit through a condenser, a reflector is arranged on one side of the light source opposite to the incident slit, the reflector, the light source and the condenser are positioned on a straight line, and the focal length of the reflector is half of the distance between the reflector and the light source, so that the light emitted by the light source is converged at the position of the light source after being reflected by the reflector. The invention can make the light of the light source opposite to the side of the condenser converge at the position of the light source after being reflected by the reflector, thereby reinforcing the energy of the light source.
Description
Technical Field
The invention relates to an oil emission spectrometer, in particular to a light source enhancing device therein.
Background
As shown in fig. 1, light emitted by a light source 1 of the oil emission spectrometer is converged at an entrance slit 3 of a light splitting unit through a condenser lens 2, and is split by a light splitting system to perform correlation analysis.
The light radiation emitted by the light source 1 is radiated in all directions, and the traditional light path only converges a part of light in the light source 1 facing the condenser lens 2 on the incident slit 3 of the light splitting system, so that the defect of low utilization rate of the light source radiation energy exists.
Disclosure of Invention
The invention aims to: the utility model provides a light source reinforcing means of fluid emission spectrometer, solves the above-mentioned technical problem that exists among the prior art.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides a light source reinforcing means of fluid emission spectrometer, the light that the light source of fluid emission spectrometer sent converges the incident slit in beam split unit through the condensing lens, its characterized in that:
a reflector is arranged on one side, opposite to the incident slit, of the light source, the reflector, the light source and the condenser are located on the same straight line, and the focal length of the reflector is half of the distance between the reflector and the light source, so that light emitted by the light source is converged at the position of the light source after being reflected by the reflector.
Wherein: the side of the reflector close to the light source is a lens structure, and a reflecting film is plated on the side of the lens structure opposite to the light source.
The invention has the advantages that: the light emitted by the light source is just converged at the position of the light source after being reflected by the reflector, so that the energy of the light source is reinforced. In addition, one side of the reflector close to the light source is a lens structure, the reflecting film is arranged on one side of the lens structure opposite to the light source, when oil mist generated by the light source is contaminated on the reflector, only the oil mist is contaminated on the lens structure, the lens structure can be cleaned by wiping without worrying about damage to the reflecting film, and therefore the service life of the reflector is long.

Detailed Description
The invention provides a light source reinforcing device of an oil emission spectrometer, light emitted by a light source 1 of the oil emission spectrometer is converged at an incident slit 3 of a light splitting unit through a condenser lens 2, and is split by a light splitting system to perform related analysis, and the structure of the part is consistent with that of the prior art;
as shown in fig. 2, compared with the existing light path, in the present invention, a reflector 4 is disposed on a side of a light source 1 opposite to an entrance slit 3, the reflector 4, the light source 1 and the condenser 2 are located on a straight line, and a focal length of the reflector 4 is a half of a distance between the reflector 4 and the light source 1, so that light emitted from the light source 1 is just converged at the position of the light source 1 after being reflected by the reflector 4, thereby reinforcing energy of the light source 1.
Because the light source 1 of the oil emission spectrometer can generate oil mist while emitting light, the oil mist is easy to be stained on one side of the reflector 4 facing the light source 1, the reflection efficiency is influenced, frequent wiping is needed, the mirror surface is easy to be damaged in the wiping process, and the reflection efficiency is permanently reduced. For this purpose, the side of the reflector 4 close to the light source 1 is a lens structure 41, and the side of the lens structure 41 opposite to the light source 1 is coated with a reflective film 42 (i.e. coated with an internal reflective film 42). In this way, when the oil mist generated by the light source 1 is contaminated on the reflector 4, only the lens structure 41 is contaminated, the lens structure 41 can be cleaned by wiping without worry, and the reflective film 42 is not damaged, so that the service life of the reflector 4 is long.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
