Abstract
A fully-sealed collimator structure is characterized in that a collimator main body is an integral sealed housing and mounted on a working platform; optical elements are arranged inside the sealed housing at the same time; all the optical elements penetrate the sealed housing to be directly fixed on the working platform through supports and sealing elements independent from the housing, and are free from the direct contact with the housing; and the light emergent opening of the collimator is provided with a high-transparent sealed window or connected with another sealing device, so as to form a larger sealing detection space. The fully-sealed collimator structure has the advantages of integration, high stability, high precision and space expandability, forms an integral sealing system, reduces the debugging and detecting difficulties, improves the debugging and detecting efficiency, can avoid the structural deformation caused by inside and outside pressure difference on the optical system, can avoid the harmful influence of the environment on the optical detection, and can be connected with other sealing devices as required by the detection, so as to combine a composite instrument or establish a larger sealing detection space.
Description
Technical field
The utility model belongs to optical instrument field, is specifically related to a kind of all-sealed parallel light tube structure.
Background technology
Parallel light tube is a kind of high-precision optical detecting instrument.On the one hand, at parallel light tube focus place set-point light source, can be used for launching the heavy caliber directional light, simulation infinite distance optical emitting system; On the other hand, place measuring element at the focus place, as graticule, optical camera etc., can be used for the dress school of auxiliary high-accuracy optics and mechanical system, also can be used for measuring the performance index such as the angle of divergence, right alignment of optical system; According to special requirement, also can carry out other more complicated optical system detection work.
At first, along with parallel light tube with treat the optics bore of check system and the increase of primary mirror radius-of-curvature, the impact of environment has become the factor of can not ignore.The impact of environment is mainly derived from air turbulence and thermograde impact.In the parallel light tube that uses large-aperture long-focus carries out high-precision optical detection, the impact of necessary Considering Turbulence and the temperature difference, an effective method builds totally enclosed measurement environment exactly, debugs and detects under this environment.
Secondly, along with the development of related optical engineering, the especially development of scientific research and engineering in space optics and laser communications needs to develop space to ground, space to the optical observation system of celestial body, star ground optical communication, deep space optical communication system.In the optics load development process of these Space Optical System, it debugs and detects general the needs through the space environment simulation test, and the space conditions such as vacuum or low temperature are mainly simulated in this test, and the ray machine load by these environmental testings just can come into operation.
Because above-mentioned reason, optical system usually need to be carried out under the environment of totally-enclosed or vacuum, therefore require parallel light tube reliablely and stablely to operate in equivalent environment.
The parallel light tube of conventional art often needs to be placed in larger packoff system under test (SUT) is detected, debugging and detection difficulty have been increased, and the malformation meeting of the unequal generation of packoff external and internal pressure affects to optical system, has reduced accuracy of detection.
Summary of the invention
In order to overcome the above-mentioned deficiency of conventional art, the utility model provides a kind of new closed parallel light tube structure.New construction will be avoided building test environment with larger packoff; Avoid the poor malformation that causes of external and internal pressure on the impact of optical system, guarantee the stability of optical system and supporting construction; Provide precision, the requirement of the fields such as meeting spatial optics, ground observation to high precision detecting instrument equipment; And has spatial scalability: can be connected connection with other packoffs according to detecting needs, form compound instrument and equipment or build larger sealing detection space.
The technical scheme of completing the foregoing invention task is: a kind of all-sealed parallel light tube structure, it is characterized in that, and this parallel light tube main body is a complete seal casinghousing, is arranged on workbench; The sealing enclosure interior is provided with optical element simultaneously; Described inner all optical elements that arrange, all the support by being independent of housing and seal pass seal casinghousing and directly are fixed on workbench, do not contact directly with housing.
Described " support and the seal of inner all optical elements that arrange by being independent of housing passes seal casinghousing and directly is fixed on workbench ", the utility model is recommended following structure:
With reference to accompanying drawing 2: pass the opening that supporting mechanism 2 that seal casinghousing refers to optical element passes seal casinghousing 5 and directly be mounted on workbench, with flexible sealing pipe 9(corrugated tube) two end flanges be fixedly connected with the seal flange 10,11 that supporting mechanism and seal casinghousing opening are provided with respectively.Like this, all parts all are included in sealed environment, and because the characteristic of the flexible buffering of flexible sealing pipe can be isolated the vibrations that come from seal casinghousing, optical element are not impacted.In simple terms, i.e. the effect of housing is to provide a sealed environment, and the degree of stability of optical element realizes by being in the outer workbench of sealed environment 1.
In prioritization scheme, the light-emitting window of described parallel light tube is equipped with high sealed window thoroughly, optical instrumentation in the direct-detection atmospheric environment, perhaps the light-emitting window of described parallel light tube is equipped with the flexible sealing pipe, the mouth of pipe is furnished with the standard flange interface and is connected connection with seal flange or the valve of another packoff, consist of larger seal cavity, optical instrumentation to be detected is placed the high precision of wherein carrying out under sealed environment detect.
In above scheme, described optical element includes: whole optical mirror slips that the parallel light tube main system comprises; Can be placed on the pointolite at parallel light tube focus place, can be used for launching the heavy caliber directional light, simulate infinite distance optical emitting system; Can be positioned over the measuring element at focus place, as graticule, optical camera etc., can be used for assisting the dress school of high-accuracy optics and mechanical system, also can be used for measuring the performance index such as the angle of divergence, right alignment of optical system, according to special requirement, also can carry out other more complicated optical system detection work.
The utility model compares with traditional parallel light tube the advantage that has:
1, integrated: the utility model has been avoided building test environment with larger packoff, and himself consists of a complete sealing system, reduces debugging and detection difficulty, has improved debugging and detection efficiency.
2, good stability: optical system and packoff support respectively, avoid the poor malformation that causes of external and internal pressure on the impact of optical system, and the stability of optical system and supporting construction all is guaranteed.
3, precision is high: sealed environment, avoided the harmful effect of environment to optical detection, and improved accuracy of detection, can meeting spatial optics, the field such as ground observation is to the requirement of high precision detecting instrument equipment.
4, spatial scalability: can be connected connection with other packoffs according to detecting needs, form compound instrument and equipment or build larger sealing detection space.
