Description

The microplate reader optical system

Technical field

The utility model relates to clinical detection equipment microplate reader, especially relates to the microplate reader optical system.

Background technology

Microplate reader is to be used for immunoreactive checkout equipment.Go out the absorbance of detected material by immunoreaction measurement, judge the content of patient's internal tag thing, thereby provide scientific basis for diseases such as clinical diagnosis tumour, acquired immune deficiency syndrome (AIDS), hepatitis B, diabetes, thyroid gland, venereal disease, impatient infraction, anemias.The microplate reader optical system mainly is made up of light source cell and light beam receiving element at present, the light that light source cell sends is given the light beam receiving element through lens, optical filter by Optical Fiber Transmission, its existing deficiency is mainly: the light emitting source in one, the light source cell adopts Halogen lamp LED more and is single lamp, thermal value is big, power consumption is high, need take off lamp body when photochromic and change when needs change, operate comparatively loaded down with trivial details; Two, the optical filtering bar is a circular configuration, the increase that causes the microplate reader volume if will extend that the number of openings of establishing thereon certainly will will increase the volume of bar shaped optical filtering bar.Its three, no light source motor-driven, the bearing accuracy when light source exchanges is relatively poor; Its four, the outgoing interface of optical fiber is circular, does not possess scan function and light energy losses is bigger;

The utility model content

The utility model purpose is to provide the microplate reader optical system that a kind of power consumption is low, be easy to the expansion of bar shaped optical filtering bar light beam through hole.

For achieving the above object, the utility model can be taked following technical proposals:

Microplate reader optical system described in the utility model, it comprises light source cell and light beam receiving element; Described light source cell is made of LED lamp, the filtering apparatus that is arranged on directly over the described LED lamp; Described filtering apparatus is made of horizontally disposed upper and lower bar shaped support and the bar shaped optical filtering bar that longitudinally is slidingly arranged on the track therebetween; Vertically offer a plurality of light beam through holes and the optical filter that places in it in described bar shaped optical filtering bar upper edge longitudinal separation; On bar shaped optical filtering bar rear wall, be vertically arranged with tooth bar and the gear driven by stepper motors that is meshed with described tooth bar; Be positioned at same position of center line place at upper and lower bar shaped rack outer surface and be provided with the optical fiber collar and the lens collar respectively, the annular distance of the described optical fiber collar and the lens collar runs through corresponding upper and lower bar shaped support respectively; In the lens collar, be provided with lens; Described light beam receiving element is following of the lens seat of honour that is provided with, the upper and lower interval of level and lens; On following of the described lens seat of honour and lens, a plurality ofly run through the light-conductive hole of its pedestal and be arranged on lens in the described light-conductive hole along horizontal spaced apart respectively being provided with; Each light-conductive hole of lens upper pedestal is connected with an optical fiber by fibre-optical splice respectively, and the other end of described every optical fiber socket-connects by the optical fiber collar in ring set and the light source cell.

Described LED lamp is two that are arranged side by side, and its lamp socket is along the vertical or horizontal adjustable type structure of level by motor-driven.

The optical fiber exit portal that is arranged in the described fibre-optical splice is a rectangular configuration.

Light-conductive hole on the upper and lower seat of light beam through hole, lens on the described bar shaped optical filtering bar is respectively eight.

Therefore the utility model advantage is that the optical filtering bar is set to strip structure, offers that thereon light beam number of openings is easy to be expanded and the installing space that do not influence the optical filtering bar, has improved the detection efficiency of microplate reader; The setting of LED lamp not only greatly reduces power consumption, also makes its thermal value greatly reduce, and has prolonged serviceable life, and the light that while LED lamp is sent is laser beam; The LED lamp is arranged side by side into different colourities two, therefore when transformation light source colourity, can moves horizontally by its lamp socket of motor-driven easily and realize need not lamp body is unloaded replacing the bearing accuracy height during the light source exchange.Therefore optical fiber exit portal in the described fibre-optical splice is set to rectangular configuration, has scan function and optical energy loss is little.
