Abstract
The utility model discloses a cell spectral measuring instrument. The utility model relates to a device for analyzing and measuring substance by optical means, particularly a cellular measuring device, comprising an optical microscopic magnifying device and a spectral analyzing device which are combined. A projection screen with optical stop is arranged in the optical microscopic magnifying device. The projection screen is connected with the input slit of the spectral analyzing device by optical fiber bundle. The utility model can be used for obtaining cellular shape information, measuring cellular structural constituents, and researching cellular spectrums.
Description
The utility model belongs to a kind of optical instrument that utilizes material is carried out the device that the device, particularly pair cell of analytical test are measured.
For the observational study of cell, traditional method is to adopt opticmicroscope or electron microscope to observe its form, and then makes normal and improper discriminating.The information that this method obtains only is confined to the form of cell, and can't obtain the information of structural constituent aspect, and therefore, the accuracy rate as a result of mensuration is relatively low.
The purpose of this utility model provides a kind of cell spectrometry instrument, and it not only can obtain the information of the form aspect of cell, the more important thing is the information that can obtain the structural constituent aspect.
The realization the technical solution of the utility model is: according to lot of experiment results as can be known, normally have significantly different with the absorption spectrum of improper cell between 200～850 nanometers, therefore optical microphotograph multiplying arrangement and spectral analysis device are constituted, promptly in the optical microphotograph multiplying arrangement, be provided with the projection screen of a band diaphragm, connecting an end of light carrying fibre bundle on the projection screen, the other end of light carrying fibre bundle is connected on the entrance slit of spectral analysis device.The sample of cell is put into the optical microphotograph multiplying arrangement, allow light source pass through cell and celliferous microscopic image on the projection screen of band diaphragm, light carrying fibre bundle will be delivered to the entrance slit of spectral analysis device through the optical signal after the cell imaging again, and the spectrum of cell is noted.
Below, according to the embodiment that accompanying drawing of the present utility model provided, its structure is done further carefully to state.
Fig. 1 is a structural representation of the present utility model;
The utility model is to be constituted by optical microphotograph multiplying arrangement 1 and spectral analysis device 2, promptly in the optical microphotograph multiplying arrangement, be provided with the projection screen S2 of a band diaphragm, an end that is connecting light carrying fibre bundle F on the projection screen S2, the other end of light carrying fibre bundle F are connected on the entrance slit S3 of spectral analysis device 2.For the spectrum of pair cell is made gratifying mensuration, the parameter of whole device and structure are provided with as follows: the enlargement ratio of optical microphotograph multiplying arrangement 1 is greater than 500 times, the observation spectral range of spectral analysis device 2 is in 200～850 nanometers, the background count rate that photoelectricity receives is better than 10pps, the setting of optical microphotograph multiplying arrangement 1 is, be provided with condensor L1 behind the light source G, to guarantee enough measuring beam intensity, being sample S1 behind the condensor L1, is magnifying glass L2 behind the sample S1, establishes a refractor R behind the magnifying glass L2, behind the refractor R beam expanding lens L3, by these optical lens group, can obtain satisfactory enlargement ratio, be the projection screen S2 that has diaphragm at last.In the technical solution of the utility model, optimized choice to diaphragm is, square 0.5 * 0.5,1 * 1,2 * 2, circular φ 0.5, φ 1, φ 2 are connected the optical fiber that diameter that the projection screen S2 that has diaphragm and the light carrying fibre bundle F between entrance slit S3 can select φ 6 for use and length are 1 meter.
The above-mentioned technical scheme that proposes by the utility model, it can reach following effect: the optical microphotograph amplifying device not only has enough multiplication factors, cell can be amplified to observable size, but also provide the intensity of enough measuring beam for the spectrum analysis device, therefore this analyzer can be used to obtain the information of the constituent of cell, for the deeper research of biology, medical science and other Relevant Subjects provides effective checkout equipment.
