Description
Technical field
The present invention relates to the medical analytical instrument, is a kind of grating monochromator that uses that is connected with the medical bio analyser.
Background technology
Use monochromator in the instruments such as present medical biochemical analysis, Pharmaceutical Analysis, what generally use is the color filter monochromator, the deficiency of this monochromator is: the accurate numerical value of difficult mensuration, color filter fugitive color particularly, easily cause the test data accuracy poorer after fading, because most of analysis indexes that analyser uses all has in a big way, so analytically unaffected at some.Yet along with the degree of accuracy of progress of science and technology and analysis data demand improves gradually, this color filter monochromator can not satisfy the request for utilization of some analyser, there are many enterprises to select imported product for use, because imported product costs an arm and a leg and causes the analysis cost of operational analysis instrument to increase significantly, particularly medical industry has increased patient's financial burden by a relatively large margin.That has reported is used for monochromator on the analyser because its complex structure, detects reasons such as data accuracy is low, can not form product so far and come into operation.
Summary of the invention
The objective of the invention is, a kind of grating monochromator is provided, it is connected use with instruments such as medical biochemical analysis, Pharmaceutical Analysiss, and material is carried out quantitatively and qualitative analysis, makes it have testing and analysis data accuracy height, long service life, the advantage that cost is low.
The present invention is achieved through the following technical solutions for achieving the above object: grating monochromator, comprise housing, lens is installed on the housing, the slit support is installed in the housing, the exit slit sheet is installed on the slit support, offer exit slit on the exit slit sheet, photoelectric cell is installed in the back side of exit slit sheet and exit slit corresponding section, photoelectric cell is connected with circuit board by lead, away from a side of lens grating is installed with lens corresponding section, slit support in the housing, offers entrance slit on the housing.Lens is installed in the lens bracket, and lens bracket is installed in hull outside.The slit support is an arcuation, and the exit slit sheet of installing on it is an arcuation.Grating is installed in the grating shell, and the grating shell is rack-mount, is installed on the support on the base plate of housing.Offer groove on the slit support.The exit slit sheet is installed in the slit mid-stent, and the exit slit of offering on the exit slit sheet is positioned at the front portion of exit slit sheet near the lens place.Offer 6-12 exit slit on the exit slit sheet.Two catch are installed on the inwall of entrance slit 1 on the housing.Frame bottom adopts screw and screw retention and adjusts the angle of support, offers regulating tank on the middle plate of support, on the middle plate of regulating tank both sides set screw is installed, and grating is installed in the middle plate front of support.
Advantage of the present invention is: it adopts light source characteristic, utilize the concentration of liquid, the biological effect of light and the optical characteristics of transparency material etc., adopt scientific and reasonable structure that light signal is converted to electric signal output, thereby reach to make and detect the high purpose of data accuracy, and prolong its serviceable life, because the present invention is the wavelength analysis data with spectrum, so can make the accuracy of data be accurate to nanoscale.The present invention compares with similar imported product, and its performance and serviceable life are suitable, and sale price reduces about 80% than imported product, particularly to medical industry, because cost of the present invention is low, thereby makes the corresponding reduction of analyser product price, thereby has reduced financial burden significantly for extensive patients.
