This invention has wide application.
Description
Technical field
The present invention relates to a kind of beam split and photo-translating system of Biochemical Analyzer.
Background technology
Biochemical Analyzer need resolve into complex light monochromatic light needed, a plurality of wavelength in the course of the work, and monochromatic light is carried out opto-electronic conversion by photoelectric commutator.In the current implementation, mainly comprise following several: (1) by rotating filtering sheet wheel and photoelectricity testing part, and a branch of complex light is resolved into the monochromatic light of a wavelength, and this monochromatic light is carried out opto-electronic conversion; (2) with a branch of complex light, by optical fiber, resolve into the multi beam complex light, again to each bundle complex light, by overlapping independently optical filter and photoelectricity testing part, the monochromatic light of a plurality of wavelength is carried out opto-electronic conversion synchronously more; (3), a branch of complex light is resolved into the monochromatic light of a plurality of wavelength simultaneously, and carry out opto-electronic conversion synchronously by grating and photodetector array.Its correspondence has the following disadvantages: (1) rotating filtering sheet is taken turns, and once can only decomposite the monochromatic light of a wavelength, once can only carry out opto-electronic conversion to a wavelength; Shortcomings such as (2) by optical fiber a branch of complex light is resolved into the scheme of multi beam complex light, it is big to have a light source power, and it is big that light path takies volume, and light path can't be totally-enclosed, and optical filter serviceable life is short; (3) grating and photodetector array, the price height, and parasitic light is relatively large.So present technology has the following disadvantages: cost height, volume are greatly, sealing is poor, measurement is unreliable.
Summary of the invention
Technical matters to be solved by this invention is to overcome the deficiencies in the prior art, and the beam split and the photo-translating system of the Biochemical Analyzer that a kind of cost is low, volume is little, totally-enclosed, reliability and durability is provided.
The technical solution adopted in the present invention is: the present invention includes casing, the color separation film array, filter arrays, photodetector array, described casing is provided with the entrance port, described color separation film array is made up of some color separation films, described filter arrays is by forming with the corresponding optical filter of color separation film quantity, described photodetector array is by forming with the corresponding photoelectric detector of color separation film quantity, described color separation film array, described filter arrays and described photodetector array are arranged in the described casing, color separation film in the described color separation film array is all angled with described entrance port, the axis of the optical filter in the described filter arrays is consistent with described color separation film reflection ray direction, described photodetector array is parallel with described filter arrays, and described filter arrays is arranged between described color separation film array and the described photodetector array.
The present invention also comprises by the lens arra of forming with the corresponding lens of color separation film quantity, and described lens arra is arranged between described filter arrays and the described color separation film array and is parallel with described filter arrays.
The present invention also comprises color separation bar, lens shim group and optical filtering bar, and described color separation film array is arranged on the described color separation bar, and described lens arra is arranged on the described lens shim group, and described filter arrays is arranged on the described optical filtering bar.
The present invention also comprises O-ring seal, gland bonnet, and described gland bonnet is fixedly installed in described casing top, and described O-ring seal is arranged between described casing and the described gland bonnet, has deposited the drying property material in the described casing, has been filled with inert gas.
The invention has the beneficial effects as follows: because color separation film of the present invention, optical filter and photodetector system all use the form of array, can carry out the analysis of the light of various wavelength simultaneously, and can select for use color separation film to select different light selectively, thereby make that cost of the present invention is low, but also make small product size less; Because the present invention has used the structure of casing and O-ring seal and gland bonnet, deposited the drying property material in the described casing, be filled with inert gas, so can guarantee the reliability of sealing of the present invention and detection light.So the present invention is the beam split and the opto-electronic conversion array system of the Biochemical Analyzer that a kind of cost is low, volume is little, hermetically sealed, reliability and durability.
