Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Such as the spectrum detection instrument sample room of Fig. 1 to 4, including sample room body 1, its unusual part is: sample
Room body 1 is spheroid, and sample room body 1 is provided with exciting light entrance 2, flashlight outlet 3, sample room connector 4.Meanwhile,
In order to effectively promote light radiation effect, in sample room body 1, it is provided with optics diffuse-reflectance inner surface structure 5.Further, examine
Consider the facility to the detection of follow-up sample presentation, in sample room body 1, be provided with sample room inner bag 6, sample room inner bag 6 is provided with sample
Product inlet 7, sample flow export 8.
From the point of view of this utility model one preferably embodiment, optics diffuse-reflectance coating can be used to constitute optics diffuse-reflectance
Inner surface structure 5.Specifically, for the ease of manufacturing, optics diffuse-reflectance coating is paint solidification film layer.Further, real in reality
Shi Shi, also can use the material of other optics diffusing characteristic diffusers to constitute this film layer, as long as meeting necessary diffuse-reflectance.
Meanwhile, the structural member of non-coating type can also be used to realize effective diffuse-reflectance.Specifically, such optics is unrestrained anti-
Penetrate inner surface structure 5 and include basic unit 9, some polyhedral structure in basic unit 9, is distributed.In order to promote diffuse-reflectance effect,
Realize Uniform Irradiation, the polyhedral structure involved by this utility model be the one in cube 10, pyramid 11, prism 12 or
Multiple combination.
From the point of view of further, in order to realize the detection needs of quick sample presentation, sampling, exciting light entrance 2, flashlight outlet 3, sample
Product room connector 4, sample injection port 7, sample flow export 8, for open type opening.In other words, this kind of open type opening is similar to
Cavity structure, actual moulding, bore can configure according to subsequent use demand.Certainly, it is contemplated that some special inspection
Survey and need, it is desirable to effective confined space is provided, at exciting light entrance 2, flashlight outlet 3, sample room connector 4, sample
Inlet 7, sample flow export 8, be equipped with independent lid 13.Further, the lid 13 that this utility model uses can be through exciting
Light and/or be flashlight.
From the point of view of further, it is contemplated that the thing to be detected placed in sample room inner bag 6 just can be excited light and flashlight
Often irradiation, does not affect Detection results, and sample room inner bag 6 can also be for spheroid, and it can pass through exciting light and flashlight.
Operation principle of the present utility model is as follows:
Can be briefly described by sample room body as closing empty ball, its cross sectional representation is as shown in Figure 3.Wherein, dA1And dA2
For two infinitely small bins of inner surface, the distance of two bins is S, and the radius of ball is R, and the radial direction of ball is face
The normal direction of unit, the angle between radius R and distance S is a.
Here, suppose that bin has the characteristic of Ideal Diffuse Reflection Lambertian.In other words, bin unit in any direction is stood
Light radiation in body angle is proportional to cos (a).Wherein, a be bin normal direction with emergent light direction add angle, total light yield is proportional to π.And
And, in the middle of actual application, the situation of general Rough Horizontal Plane is the most close with this.Thus, bin dA1The light launched is by bin dA2Receive
Ratio is
As can be seen here, in ball, any bin is identical from the light radiation received by another bin any, itself and angle
Unrelated, unrelated with launching bin.If by infinitely small bin dA2Change the area A of limited size into2, then result above becomes face
Long-pending A2The ratio receiving light isWherein ASArea for ball.Thus it is not difficult to find out, if (reality should with diffuse-reflectance
It being matsurface in) face constitutes the inner surface of ball, and the light radiation that its internal any bin receives is identical, the most uniformly
's.
From the point of view of the sample room schematic diagram shown in Fig. 4.Wherein AiFor exciting light entrance port, AeFor flashlight exit portal, A
For exciting light direct projection area, ASFor ball inner surface area, ρ is reflectance, FiFor exciting light flux.Also assume that bin has reason
Think the characteristic of diffuse-reflectance Lambertian, then face to be illuminated amasss the brightness-formula of A and isWherein π is normalizing constant.
Assume AiAnd AeArea and ASCompare less, and set ball inner surface as Ideal Diffuse Reflection, according to previous Fig. 3's
Specifically describe, the light radiation that ball inner surface receives everywhere is identical, then after a diffuse-reflectance ball inner surface receive total
Luminous flux isWherein f is AiAnd AeArea and with ball surface area ASRatio
Example.
In like manner, the total light flux that the ball inner surface produced after n-th reflection receives is Fiρn(1-f)n.N secondary reflection is produced
The total light flux that raw ball inner surface receives is added and obtainsIt is assumed here that f ＜ 1 (typically smaller than 10%).
Therefore, the brightness of ball inner surface is
WhereinAs can be seen here after repeatedly diffuse-reflectance the brightness of inner surface from incipientRise toI.e. improve M times.
For example, it is that 5% (the area sum of exciting light entrance port and flashlight exit portal accounts for ball gross area ratio as f
Example), when reflection coefficient is 98%, M is 14, i.e. signal intensity improves 14 times, and this is attributed to the most anti-at ball inner surface of light
Penetrate.
From the point of view of actually used, in application principles above to spherical sample room provided by the utility model, a branch of low
The exciting light (or detection light) of power, improves 14 times at ball inner surface through multiple reflections, brightness, can excite more sample
Spectral signal.In like manner, certain sample spectral signals is also exaggerated 14 times through multiple reflections, and both are multiplied obtained signal
To be original 196 times.Therefore, this sample room can be effectively improved the signal collection efficiency of portable measurement equipment and measure essence
Degree.
By above-mentioned character express and combine accompanying drawing it can be seen that this utility model is gathered around has the following advantages:
1, disclosure satisfy that gas, holding of liquid test needs, it is achieved the diversification of test sample.
2, the interaction of sample and exciting light can be effectively improved and amplify spectral signal, thus it is strong to improve spectral signal
Spend and reduce signal noise.
3, unitary construction is simple, it is easy to assembling manufacturing, it is simple to safeguard, various spectrum detection instrument can be coordinated in sample room
Sample carry out spectral detection and analysis.
The above is only preferred implementation of the present utility model, is not limited to this utility model, it is noted that
For those skilled in the art, on the premise of without departing from this utility model know-why, it is also possible to do
Going out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
