Description
Technical field
The present invention is about a kind of high-performance illuminator for fluorescence photography device, particularly about a kind of photofluorographic high-effect fluorescence photography device of biological sample colloid that is applied to.
Background technology
In giving birth to the skill experiment, for all eucaryotes, by the phosphorylation of protein, can make body change intracellular protein activity, change the activity of ferment or use and transmit signal, regulate cellular metabolism, growth, propagation and canceration or the like physiology course.But generally speaking, phosphorylating protein content is extremely low, and normal in vivo journey mobile equilibrium, without the pre-concentration step, often can't effectively detect or carry out biological test.
Develop the west from people such as Towbin in 1979 and change stain method protein such as (Western blot) or nucleic acid (DNA (deoxyribonucleic acid) for example; DNA) after the analytical technology, the west is changeed the stain method and is become extremely welcome analytical approach.The superior analytic ability of stain method association colloid electrophoresis (gel electrophoresis) is changeed in the west, and the technology of the characteristics such as susceptibility of the selectivity of antibody and ferment (enzyme), can in the very complicated compound of composition, a particular proteins or DNA be separated.Sample after utilizing colloid electrophoresis to separate after video picture is handled, can carry out qualitative or quantitative observation again.
And according to the characteristic of sample, employed reagent or stain difference in colour developing or videograph process, the view mode of its sample after video picture is also different.For example, in the observation of DNA fluoroscopic image, the blue light-emitting diode (LED) that need to use wavelength 465nm is as back light, uses the dna sample that excites after the video picture and sends fluorescence, re-uses optical lens and video camera and carries out that shadow is observed or shooting.
See also Fig. 1, be the diagrammatic cross-section of existing fluorescein photographic equipment.As shown in the figure, existing fluorescein photographic equipment 10 consists predominantly of a camera module 12, one amber optical filter (amber filter) 141 and one light source module 18.
Wherein, light source module 18 includes housing 181, and an opening is established in housing 181 tops, and is embedded a blue color filter 187 in opening.The opening below then is provided with a blue light-emitting diode array 183.The DNA colloid 16 of having finished colloid electrophoresis can be positioned on the blue color filter 187.
Utilize blue light-emitting diode array 183 to provide blue light, and, make the light of specific band pass through with blue color filter 187 filtering parasitic lights as excitation source.Send fluorescence by the DNA in the blue-light excited DNA colloid 16 of wavelength 465nm, observe or take fluoroscopic image with camera module 12 again.
For strengthening contrast effect, can set up an amber optical filter 141 in camera module 12 and 16 in DNA colloid, use the filtering back light.In addition, for preventing LED source bright spot interference images or testing result, need a diffusion sheet 185 is set between light emitting diode matrix 183 and blue color filter 187, make pointolite be diffused in the bigger area and become comparatively uniform light source.
Though above-mentioned existing fluorescein photographic equipment can reach the effect of PF and observation, yet because of its constructional restriction, a device can only be applicable to the application of single wavelength excitation source.And the intensity that the setting of diffusion sheet 185 will the loss excitation source in its light source causes the waste of the energy.
Above-mentioned light source module 18 is a backlight arrangement (trans-illuminator), and the fluorescein photographic equipment that other has a light supply apparatus in a kind of use (epi-illuminator) as shown in Figure 2.
As shown in the figure, this fluorescein photographic equipment 20 includes: camera module 22, one amber optical filter 24, an and light source module 26.
Wherein, this light source module 26 includes a housing 269, and housing 269 tops are provided with an opening 261.Housing 269 bottoms are provided with a black substrate 265, and the DNA colloid 28 that desire is observed can be positioned on the black substrate 265 of these opening 261 belows.
Blue-ray LED array 263 is arranged in the zone outside the housing 269 inner and upper openings 261, with irradiation DNA colloid 28 under the oblique side direction, uses exciting DNA colloid 28 to produce fluorescence.
The fluorescein photographic equipment 20 of this pattern owing to blue-ray LED array 263 shines, and utilizes black substrate 265 to absorb most spuious blue light downwards, can prevent the shooting or the observation of light source bright spot interference fluoroscopic image.The amber optical filter 24 filtering blue lights of arranging in pairs or groups again can contrast preferable PF imaging.
Yet, the problem of consideration irradiation average degree and light source and DNA colloid 28 distances, its blue-ray LED array 263 needs to use many row's blue-ray LEDs, and need improve the distribution density of LED, just can obtain preferable radiation response.And, because the relation that structure is provided with forms a large amount of waste irradiation districts 267 in housing 269 inner meetings.So, not only cost of manufacture is high, also can produce a large amount of energy dissipations during use.
In addition, above-mentioned two kinds of existing fluorescein photographic equipments because of the mechanism of its use and irradiation principle need suitable distance just can obtain uniform radiation response, so its device has sizable volume, can't dwindle.
