Penetrate in photoelectric sensor, be changed into electric signal.The power of the electric signal obtained by analyzing photoelectric sensor, it is possible to analyze
Draw the strength of fluid in ELISA Plate.
In actual use, existing interference filter chip microplate reader has as a drawback that：
1st, when measuring testing concentration using interference filter chip microplate reader, it is necessary to first recall main inspection wavelength,
Put on ELISA Plate plus artificial zero check, then examine solution to be checked, then recall secondary inspection wavelength, ELISA Plate will also add artificial
Zero check is put, and examines solution to be checked again, and a kind of inspection of solution needs multi-pass operation, easily because the error of operating personnel causes
The deviation of testing result；
2nd, the optical filter of interferometric filter microplate reader sets limited amount, and each interferometric filter wavelength is fixed, general instrument
Device is main to examine wavelength and the secondary selection generally each 4 for examining wavelength, it is impossible to meet the inspection of a variety of kind of inspection not over 8
Test needs；
3rd, it is usually 8~10nm that interferometric filter microplate reader half-wavelength is very wide, and monochromatic wavelength variation range is big, wavelength
Inaccuracy, the inspection poor accuracy of instrument；
4th, interference filter on piece is coated with many layer films, and the film of these multilayers prevents monochromatic light energy to a certain extent
Propagation.The monochromatic light of interferometric filter microplate reader sufficient intensity in order to obtain, the light source of interferometric filter microplate reader are generally set
It is all bigger to count power, supply voltage requirement is higher, this is just according into interferometric filter microplate reader volume is big, quality is big, takes up an area
Area is big, energy consumption is big, and the species that these features are all only applicable to laboratory inspection sample simply tests use, is not suitable for a variety of
Sample mixing is examined or same sample many kinds of substance examines composite test to need at the same time, can not meet it is mobile examine laboratory or
Inspect the demand that sample site is examined by random samples.
Utility model content
