Abstract
The invention discloses an optical system for a spectrophotometer of a biochemical analyzer. The optical system for the spectrophotometer of the biochemical analyzer comprises an illuminating system, a beam splitting system and a signal processing system, wherein the illuminating system comprises a light source, a lens, a cuvette and a focusing lens, and the beam splitting system comprises half lenses, optical filters and a receiving photodiode. The light source, the lens, the cuvette and the focusing lens are arranged in sequence. The light source transmits rays, and the rays are collimated through the lens and are radiated into the cuvette in parallel. The rays are radiated into the focusing lens in parallel after penetrating through a sample arranged in the cuvette. Parallel light beams are used as an optical signal and transmitted to the beam splitting system after being focused to be a point light source. The optical signal passes through sixteen half lenses in sequence, and when the optical signal passes through each half lens, a light beam with a designated wavelength is reflected to the corresponding optical filter. The optical signal is converted into a digital signal through the photodiode and transmitted to the signal processing system to be processed in a comparison mode. The optical system for the spectrophotometer of the biochemical analyzer improves the detecting efficiency and the detecting precision.
Description
Technical field
The present invention relates to biomedical measurement and technical field of medical instruments, particularly a kind of for the spectrophotometric optical system on the Biochemical Analyzer.
Background technology
Automatic clinical chemistry analyzer is mainly used in clinical blood, and the biochemistry in the humoral sample and the fast quantitative analysis of chemical constitution, automatic clinical chemistry analyzer are the conventional sense instruments of modern hospital.
As the critical component of automatic clinical chemistry analyzer, spectrophotometric performance becomes the principal element that determines the automatic clinical chemistry analyzer precision index.In numerous spectrophotometric beam splitting systems, according to light splitting sequencing difference, preceding light splitting and back beam splitting system can be arranged; According to the difference of the chromatic dispersion device of practicality, the beam splitting system of prism, grating and optical filtering chip can be arranged; And optical filtering chip beam splitting system, because a kind of optical filter can only have filter effect to certain certain wavelengths, be difficult to accomplish that the spectrum of properties of multi-wavelength detects, so the common general form of rotating filtering sheet that comprises of optical filtering chip beam splitting system is selected wavelength more on the market.The beam splitting system of this form needs to consume the regular hour when selecting wavelength; And because the characteristic of its rotation has been brought certain instability and failure rate.And the light path system of the discrete fully-automatic analyzer in the market eight road beam splitting systems that adopt once can only be done the detection of eight biochemical indicators to sample more, have retrained the efficient of analytical work greatly, simultaneously also because repeatedly comparison has influenced the detection comparison accuracy.
Summary of the invention
Technical matters to be solved by this invention provides a kind of for the spectrophotometric optical system on the Biochemical Analyzer, its improved detect efficient, also improved simultaneously the precision that detects.
For solveing the technical problem, the invention provides a kind of for the spectrophotometric optical system on the Biochemical Analyzer, it is characterized in that it comprises illuminator, beam splitting system and signal processing system, wherein illuminator comprises light source, lens, cuvette, condenser lens; Beam splitting system comprises semi-permeable mirror, optical filter, reception photodiode, light source, lens, cuvette, condenser lens are arranged in order, the source emissioning light line is through parallel injecting in the cuvette after the collimated, after light sees through sample in the cuvette, the parallel condenser lens of injecting again, after parallel beam is focused into pointolite, be transferred in the beam splitting system as light signal, light signal is successively by 16 semi-permeable mirrors, every through a slice semi-permeable mirror, can be with the beam reflection of specified wavelength to its corresponding optical filter; Light signal is converted to digital signal by photodiode by light signal again, and transfers to signal processing system and compare processing.
Positive progressive effect of the present invention is: the invention solves optical filtering chip beam splitting system and select wavelength long defective consuming time; The present invention once can do the detection of 16 biochemical indicators to sample, improved greatly detect efficient, also improved simultaneously the precision that detects; Owing to used a light source, improved the degree of accuracy of colorimetric and detection.The present invention is simple in structure, stable performance, resolution height, and good reproducibility.
