Filter for Medical Biochemical Analyzer  

       

We have developed and produced the special interference filters forbiochemical analyzers since 1988, and till now have developed and producedthree types, four size series, nearly 30 wave lengths and more than 80specifications standard  biochemicalfilters which are mainly used for biochemical analyzers,  microplate readers and other biochemical  analysis instruments.

We provide high-quality interference filters for over 80% domesticbiochemical analyzer and microplate reader manufacturers. We also providehigh-quality interference filter assemblies for special maintenance centers andagencies in China comingfrom USA, Denmark, Netherlands,Italy, Spain and other foreign biochemicalanalyzer manufacturers.

It has ultra-high signal-to-noise ratio, and background suppression ofOD5-OD6 (T=10-5-10-6), and this can make surethat the instrument can do accurate measurement in the absorbance range of A=2to A=4.  


Types of StandardBiochemical Filters

     

     UniversalType (type I) : It is widely applied to various biochemical analyzers andmicroplate readers.

HighSNR Type (type II): The filter has the background of less than 10-50.001%, has high SNR, and is suitable for biochemical analyzersand microplate readers having higher requirements on SNR.

       EnergyMatching Type (type III) :it is specially designed, and the energy distributionof each wave length is matched with the optoelectronic system of the halogenlamp and silicon photodetector so that the optoelectronic signal output by thesystem tends to be balanced.

Standardsize series: diameter: 10mm, 12mm, 15mm, and 20mm  

Standardwavelength series: 340, 380, 405, 450, 492, 546, 578, and 630nm

Anyoptical filer for the biochemical analyzers with the wave lengths within 330nmto 1100nm can be ordered and produced.


Precision OpticalReflector

       

Reflector is a reflectioncondenser element which is widely applied to optical condenser systems such asfilm projector, searchlight, luminaries, decorative lighting,  projector, optical fiber lighting, medicaland bio-instruments and the like. SAIS is thereflector production unit with the maximum scale in China, and has the domestic marketshare of more than 70%. Products are exported to the United States, Germany,Italy, India, Israel and Southeast Asian.SAIS  is a base researching andmanufacturing domestic diathermic reflector for film projector, and hasdomestic leading coating production line for optical fabrication and aspherical reflectors. Formany years, SAIShas committed to the research and production of professional precision opticalcomponents.

In 2008, SAISsuccessfully developed the first set of diathermic reflector for digital filmin China,and the diathermic reflector has been produced in batch.

Numerical controlmodeling technique and precision polishing are used as optical fabrication ofprecision optical reflector for digital film. The inside surface is coated withhard multilayer dielectric coatings by using the ion-assisted deposition, theoptical film reflects the visible light emitted by light source, transmits nearinfrared light, has high utilization efficiency of light source, and improvesthe thermal stability of the system.

NeutralDensity Filter

      

       Neutraldensity filter is a filter which can attenuate light intensity but cannotchange the energy distribution of spectra. On the premi se of keeping neutral distribution of  spectra, neutral density filter dynamicallyand continuously adjusts the total light energy transmitted through the systemor controls the light intensity distribution of beam of light (section) indifferent positions.  Neutral densityfilter is applicable to adjustment of light energy from ultraviolet spectrum,visible spectrum  to near infraredspectrum. The optional spectrum attenuation range is 250-2500nm.  The product is mainly applied to the field oflaser, optical communication, photography, astronomy and laboratoryresearch.          

       SAIS is afirst manufacturer that independently researches and develops and manufacturesneutral density filters in China,and has developed and produced six kinds of neutral density filter products.

Special Filter for Fluorescence Microscope

     

   Application:fluorescence microscopy, biological chip, gene chip, fluorescence probe and thelike

Years of manufactureexperience: SAIShas the history of more than ten years of researching and developing andmanufacturing special filter for fluorescence microscope, and provideshigh-performance fluorescence optical filters to customers at home and abroadby independent  design and manufacture,cooperative design and production and OEM mode. At present, the primary special fluorescence microscope manufacturingplants and epifluorescence device manufacturing units in China adopt the filter products of SAIS.

Beinggeared to international fluorescence microscope products:

SAIS carried out comprehensive promotionand important improvement on the design parameter, performance index andmatching combination scheme of special filter for fluorescence microscopeaccording to the development trend of fluorescence microscope at home andabroad, forming  series special filtercombination products for fluorescence microscope being geared to internationalfluorescence microscope products.  

Allinterference filters

All the excitationfilter, color separation filters and cut-off filter use hard  coated interference filters, thoroughlysolving the problems of poor cutoff characteristic and unreasonable matchingwhen colored glass filters is used as cutoff filter.

Advanced  testing method, reliable product quality:

SAIS has the internationally advancedLambda900, Cary300 spectrophotometers at present which are used for spectralcharacteristics test and background matching combination of filters, strictlyensuring the product quality.
