Description
Technical field
The invention belongs to technical field of medical instruments, design a kind of technology that is used for automatic clinical chemistry analyzer illumination path, beam split light path and link light path.
Background technology
Automatic biochemistry analyzer is a kind of Medical Instruments based on youth's primary-Beer law.As the critical component of automatic clinical chemistry analyzer, the performance of optical system is very crucial, directly the performance of decision device.The light path system of Biochemical Analyzer use at present in illumination section, comprises preceding beam splitting system, back beam splitting system; In colour splitting system, holographic flat field optical-mechanical system of concave surface and filtering slice system are arranged; On two light path on-link mode (OLM)s, there is direct use slit to receive illumination light and use simple optical fiber reception illumination light method.At present, back beam splitting system progressively replaces preceding beam splitting system, and optical-mechanical system progressively replaces the filtering slice system.Only directly use the slit link in the middle of two light path system, guaranteed light harvesting intensity, but this link method requires two light path system uniting and adjustment, has increased the debugging difficulty of light path system, has reduced the stability of light path system.This optical system uses the back to divide lighting system, the holographic flat field grating splitting system of concave surface, and the bundling optical fiber that the use multifiber is formed is as link two light path systems.
Summary of the invention
It is simple to have the objective of the invention is at employed design of Optical System in the present Biochemical Analyzer one nested structure, and wavelength repeatability is good, stable automatic clinical chemistry analyzer light path system.
Automatic clinical chemistry analyzer optical system of the present invention, comprise: the halogen light source [1] of band Lamp cup, collimation lens [2], cuvette [3], collector lens [4], bundling optical fiber [5], slit [6], the holographic flat field grating [7] of concave surface, photoelectric array detector [8], AD data-converting block [9], the direction of propagation along light, be followed successively by the halogen light source [1] of band Lamp cup, collimation lens [2], cuvette [3], collector lens [4], bundling optical fiber [5], slit [6], the holographic flat field grating [7] of concave surface, photoelectric array detector [8], photoelectric array detector [8] collects light signal after AD data-converting block [9] is transported to Computer Processing again.
The present invention uses the optical fiber more than two to receive head as optics, and optical fiber is lined up a branch of importing light in the beam splitting system.Its advantage be can illumination path and the beam split light path separately, improved the stability of two parts light paths; Because use optical fiber, is guaranteed two light path systems as web member and is changed convenient respectively; Use multifiber to replace an optical fiber, increased the light harvesting of light intensity.
The invention has the beneficial effects as follows:
1, assembling is simple.This optical system is divided into two parts with light path system, illuminator and beam splitting system, two system's debugging separately respectively, after debugging finishes, use optical fiber as chaining part, can simply assemble, problem has taken place in any one system in the day latter two systems, only need change one of them system and get final product, deduct the trouble of uniting and adjustment after changing with the situation of changing parts;
2, can to survey be 14 wavelength such as 340,380,405,425,450,480,505,524,546,578,600,630,660,700 in the present invention, and the linear dispersion inverse has reached 10nm/mm.
3, the bundling optical fiber that uses multifiber has improved light collecting light ability as the web member between the light path, has guaranteed light harvesting intensity.
