Abstract
The utility model relates to a sensor, especially a miniature full-spectrum sensor. Based on the sequence that a light path passes through all parts of the sensor, the sensor comprises a light source, a reflection prism, an objective lens, a reflector, a slit unit, a collimating mirror, an optical grating, a focusing mirror, and a photoelectric converter. The sensor also comprises a sealed cavity and an amplification circuit. The light source, the reflection prism, the objective lens, the reflector, the slit unit, the collimating mirror, the optical grating, the focusing mirror and the photoelectric converter are all located in the sealed cavity. The amplification circuit is connected with the photoelectric converter. The sensor is advantageous in that the extraneous interference is avoided because all elements are disposed in the sealed cavity, thereby enabling the stray light in the whole sealed cavity to be less, and enabling the sensitivity to be high. Meanwhile, the sealed cavity can be used independently without depending on an external light source, and the sensor is low in requirement for an application environment.
Description
Technical field
The utility model relates to a kind of sensor, refers to especially a kind of miniature full-optical spectrum sensor.
Background technology
Ultraviolet detection technology is the another important detecting technique after Laser Detection Technique and infrared detection technique, is widely used in the fields such as military affairs, commercial production, medical diagnosis.Traditional miniature full-optical spectrum sensor is light beam of light source and by optical fiber, imports airtight cavity and carry out analyzing and processing.The shortcoming of this external power supply is: 1, use inconvenience, and high to the environmental requirement of using; When 2, optical fiber imports light, easily bring impurity light into, impact analysis result.
Utility model content
The purpose of this utility model is to provide a kind of meet various environmental demands, highly sensitive miniature full-optical spectrum sensor.
The technical solution of the utility model is achieved in that a kind of miniature full-optical spectrum sensor, order according to light path through this each element of sensor, this sensor comprises light source, reflecting prism, object lens, catoptron, slit unit, collimating mirror, grating, focusing mirror, photoelectric commutator; Also comprise airtight cavity and amplifying circuit, described light source, reflecting prism, object lens, catoptron, slit unit, collimating mirror, grating, focusing mirror, photoelectric commutator are all positioned at this airtight cavity, and described amplifying circuit is connected with photoelectric commutator.
Compared with prior art, the beneficial effects of the utility model are: adopt after said structure, due to all elements that comprise light source are all arranged in airtight cavity, avoided external influence, make the parasitic light in whole airtight cavity little, highly sensitive.Simultaneously airtight cavity can independently be used, and needn't rely on external light source, to environment for use require low.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment technical scheme, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only that this practicality is in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of miniature full-optical spectrum sensor as shown in Figure 1, the order according to light path through this each element of sensor, this sensor comprises the light source 10 of launching light beam, this light source 10 is LED lamp, easy to use, stable, can certainly be other light source, as uviol lamp, infrared lamp etc.; Reflecting prism 11; For assembling the object lens 12 of light beam; Catoptron 8; Slit unit 7, the throughput of these 7 pairs of light beams in slit unit limits, and described slit unit 7 comprises quartz substrate, is coated with lighttight metal film in described quartz substrate, on described metal film, be carved with slit, slit width reduces to improve spectral resolution, but light throughput is little, signal strength weakening, slit width increases can improve light throughput, but resolution can reduce, according to the integration requirement of light percent of pass and resolution, selection slit width is 5-100um; Collimating mirror 6, for the divergent beams of incident are focused on to transmitting, described collimating mirror 6 is a concave mirror, and the divergent beams of incident are converged to output, while making outgoing beam arrive grating 5, light beam just covers grating 5, otherwise light beam causes too greatly energy dissipation, the too little grating of light beam 5 subregions can not utilize, be equivalent to grating 5 groove numbers and reduce, affect spectral resolution; Grating 5, this grating 5 is holographic grating, accepts and make light beam dispersion; Focusing mirror 4, the light beam for focus reflection after grating 5 dispersions, makes its useful area that just covers photoelectric commutator 3, and this focusing mirror 4 is all similar with the structure of collimating mirror 6, is similarly concavees lens, and its design concept is also similar to collimating mirror 6; Photoelectric commutator 3, i.e. ccd detector, for carrying out opto-electronic conversion to light beam.
Also comprise airtight cavity 1 and amplifying circuit 2, described light source 10, reflecting prism 11, object lens 12, catoptron 8, slit unit 7, collimating mirror 6, grating 5, focusing mirror 4, photoelectric commutator 3 are all positioned at this airtight cavity 1, and described amplifying circuit 2 is connected with photoelectric commutator 3.On this airtight cavity 1, be provided with output unit 9, easy to use.Due to all elements that comprise light source 10 are all arranged in airtight cavity 1, avoided external influence, make the parasitic light in whole airtight cavity 1 little, highly sensitive.Simultaneously airtight cavity 1 can independently be used, and needn't rely on external lamp source, to environment for use require low.
Further, described grating 5 is arranged on prism; 5 pairs of light beams of grating carry out internal reflection like this, are equivalent to light beam to carry out secondary dispersion, improve the resolution of spectrum.
Further, equal metal-plated membrane on described catoptron 8, focusing mirror 4 and collimating mirror 6; Can improve the reflectivity of light beam like this.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
