Abstract
The utility model relates to an inclined fluorescence picking instrument comprising a laser device, a sample platform, a fluorescence collecting device, is characterized in that an oblique angle is arranged between an emission axial and the sample platform, an optical axis of the fluorescence collecting device is positioned in the up and down sector angles using the laser emission axis and a reflected ray on the sample platform as a boundary, wherein the sector angle uses the reflected ray as a zero degree line, and ranges from 5-30 degrees, and the included angle between the laser emission axis and the optical axis of the fluorescence collecting device is more than 2 degrees, the utility model has the advantages that the device is capable of causing the fluorescence emitted by a biological media sample and the laser which agitates the biological media sample divided into two ways, in order to reach a high fluorescence picking signal/noise ratio.
Description
The utility model relates to a kind of fluorescence and picks up instrument, and particularly a kind of oblique formula fluorescence picks up instrument.
The fluorescence that the Biomedia sample sent when at present used Biomedia fluorescence picked up instrument work usually in the laboratory with excite the Biomedia sample laser carried out is same light path, so in fluorescence, be mixed with in a large number by the laser noise of sample and solid substrate scattering, because the efficient of LASER Excited Fluorescence is not high in the general Biomedia, and optical maser wavelength and photoluminescence peak wavelength are comparatively approaching, and the signal to noise ratio (S/N ratio) of having relatively high expectations is difficulty very.
The purpose of this utility model provides a kind of fluorescence that the Biomedia sample is sent and carries out oblique formula fluorescence along separate routes with the laser optical path that excites the Biomedia sample and pick up instrument.
Technical solutions of the utility model design oblique formula fluorescence and pick up instrument, comprise laser instrument, sample platform, phosphor collection device, it is characterized in that: the emission shaft of laser instrument is to the sample platform one oblique angle being arranged, the reflected ray that the optical axis of phosphor collection device is positioned at laser instrument emission axis and sample platform is two segment angles up and down on boundary, and the optical axis included angle of the emission shaft of laser instrument and phosphor collection device is greater than 2 degree.
The utility model has the advantages that to make fluorescence that the Biomedia sample sends and excite the laser optical path of Biomedia sample to divide two-way, pick up signal to noise ratio (S/N ratio) to reach higher fluorescence.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Comprise laser instrument 1, sample platform 2, phosphor collection device 3 among the figure, it is characterized in that: the emission shaft 4 and the sample platform 2 of laser instrument 1 have an oblique angle 5, the reflected ray 7 that the optical axis 6 of phosphor collection device 3 is positioned at laser instrument 1 emission axis 4 and sample platform 2 is two segment angles 8 up and down on boundary, segment angle 8 is to be 5 to 30 degree scopes of zero degree line with reflected ray 7, and the emission shaft 4 of laser instrument 1 is to spending greater than 2 with optical axis 6 angles of phosphor collection device 3.Emission shaft 4 owing to laser instrument 1 during use has the angles greater than 2 degree to the optical axis 6 with phosphor collection device 3, and the reflected ray 7 that the optical axis 6 of phosphor collection device 3 is positioned at laser instrument 1 emission axis 4 and sample platform 2 is two segment angles 8 up and down on boundary, therefore can avoid being mixed with in the fluorescence in a large number by the laser noise of sample and solid substrate scattering, this mainly is because the energy of scattering laser has very big variation with angle, and fluorescence intensity is to the insensitive characteristic of angle, though have some to be sneaked into by the laser noise of sample scattering this moment, but laser ground unrest energy greatly reduces, and can reach higher fluorescence and pick up signal to noise ratio (S/N ratio).
