Description
Technical field
The present invention relates to optical technology and sample analysis technical field, particularly relate to a kind of multiple reflections lightProduct analytical system imitates.
Background technology
Along with improving constantly of instructions for use, to the performance of optical instrument proposed more stable, more miniaturization,The more high more and more higher requirement of integrated level. Wherein optical window is as the entrance of most optical instrumentsAnd outlet, its installation and the directly reliability of the whole optical instrument of impact of sealing, Rig up error even canCause whole optical system imbalance, cause optical instrument to lose efficacy. Need especially to propose, at optics instrumentIn device, significant (as used some optical instruments or disliking in seawater to the sealing of optical componentThe optical instrument using under bad environment), in general, seal approach improved optical element moisture resistivity,The performances such as corrosion resistance, waterproof, mildew-resistant.
As shown in Figure 1, (Fig. 1 only shows except long light path in prior art, to form optical sample analytical systemThe part in pond, generally long optical path pool at least comprises two speculums and an incidence window) the first lightIt is disconnected from each other learning device, and wherein M1 is speculum, and W1 is optical window, between W1 and M1Separate, due to the obstructed light of mirror M 1, can be of living in through optical window W1 in order to meet lightPosition, need light hole be set at mirror M 1 correspondence position. For ensureing the stability of optical instrument, lightThe installation of learning window W1 fix and W1 and M1 between sealing extremely important.
As shown in Figure 2 a, 2 is that mirror M 1,3 is optical window W1 to a kind of common fixed form, 1,5,6 for to meet the set structural member of fixing seal, and 4,7,8,9 is potted component.
There is many defects in this installation fixed form:
(1) must make structural member as shown in Figure 2 stationary window W1 is installed, structural member is various,Increase the manufacturing cost of instrument;
(2) in order there to be enough space mounting optical window W1, must be between W1 and M1Reserved certain gap, thus cause effective optics of optical window W1 and mirror M 1 to utilize areaReduce;
(3) in order to reach the object of installation, the mounting fixing parts of optical window need to be from speculum installed partFront end extend into optical window installation site with cantilevered fashion, simultaneously due to the restriction of installing space, knotMember need be made the thin-walled parts that intensity is not high, due to unstability and the structural member of cantilever thin-wall constructionThe double influence of mismachining tolerance, the stability that optical window W1 installs can not be guaranteed, and installs and fixesCheng Jiqi complexity;
(4) the structural member material of stationary window is generally selected metal material, makes the material one of optical windowAs be glass, and metal material and glass material thermal coefficient of expansion generally differ an order of magnitude, in temperatureWhen variation, both deformation differences, can cause certain stress to produce, if stress acquires a certain degree,Can cause that optical element is cracked.
There is equally many restrictions for the sealing between optical window W1 and mirror M 1:
(1) between W1 and its fixture the design alternative of potted component 4 generally need consider size,Soft or hard degree of whether high temperature resistant, whether corrosion-resistant, material etc. Because insert space size is less and notTool is popular, does not have the seal of standard available on market, need to customize non-standard, has increased lifeProduce cost and the maintenance cost in later stage;
(2) potted component 8 between optical window W1 and mirror M 1 can cause mirror M 1 inningsPortion is stressed, easily causes stress to be concentrated herein, along with the use of instrument, can make mirror M 1 exist and breakRisk.
In addition, (factor that causes shift in position comprises the shift in position of optical window: the temperature difference causesDisplacement, extraneous vibration, gas shock etc.) larger on the impact of light path, especially to based on multiple reflectionsThe long light path system of technology, its impact is destructive often.
