A telescope tube: the first telescope tube 11, the second telescope tube 21, third telescope tube 31 and three spectroscopes: first point
Light microscopic 12, the second spectroscope 22, third spectroscope 32.
Wherein, each telescope tube (the first telescope tube 11, the second telescope tube 21, third telescope tube 31) is equal
For Focusable telescope tube, first telescope tube 11, the second telescope tube 21, third telescope tube 31 respectively includes one
A negative-power lenses 7 and a positive power lens 8；It can be using the negative light being arranged inside mechanical system adjustment telescope tube
Spacing between power lenses 7 and a positive power lens 8.
Shown in Fig. 2, there are two types of modes of emplacement for the telescope tube interior lens:
As shown in the left side Fig. 2, along the incident direction of laser beam, negative-power lenses 7 are in preceding, positive power lens 8
Rear, the focal power absolute value of positive power lens 8 is greater than the focal power absolute value of negative-power lenses 7, and laser beam obtains
It expands, expands than being determined by the ratio between negative-power lenses 7 and the focal power of positive power lens 8；

The laser beam that body laser 30 emits, and sent out completely through the first semiconductor laser 10 and the second semiconductor laser 20
The laser beam penetrated.
The laser beam of the different semiconductor laser passes sequentially through corresponding telescope tube, and through being divided
After mirror reflection, beam is closed by optical shaping system, laser beam both horizontally and vertically obtains different degrees of shaping,
Laser beam after shaping is respectively formed an oval Gauss hot spot with a tight waist finally by condenser lens, meanwhile, adjust semiconductor
Laser and fine tuning telescope tube position are located on cell flow chamber so that focusing the ellipse formed hot spot with a tight waist.
The telescope tube includes the lens 7 of at least one positive light coke and the lens 8 of at least one negative power；Laser
When light beam passes through the telescope tube, laser beam is able to expand or compress, expand than or compression ratio by inside telescope tube two
What the ratio between focal power of a lens determined.Since telescope tube is Focusable, telescope tube can be adjusted according to actual needs,
Realize laser beam expand than or compression ratio consecutive variations.
The optical shaping module 4 is a prism to 9 or cylindrical lens 10；The optical shaping module 4 only will be to laser
Shaping is compressed or expanded to the horizontal or vertical direction of light beam, and to another direction not shaping；
The condenser lens 5 is the achromatism balsaming lens of a positive focal power.
Above-mentioned this semiconductor laser working principle is as follows:
The light beam of first semiconductor laser 10 transmitting is by the way that after corresponding first telescope tube 11, laser beam is obtained
To expanding or compressing, beam expander ratio or compression ratio are by the negative-power lenses 7 and positive light coke inside the first telescope tube 11
The ratio between focal power of lens 8 determines that later, laser beam is incident on optical shaping module 4 after the reflection of the first spectroscope 12；
After corresponding second telescope tube 21, laser beam is expanded the laser beam of second semiconductor laser 20 transmitting
Beam or compression, beam expander ratio or compression ratio determine by the ratio between two power of lens inside the second telescope tube 21, later,

Shaping will only be compressed to the horizontal or vertical direction of laser beam or expanded to the prism pair or cylindrical lens,
And to another direction not shaping；
Semiconductor laser (the first semiconductor laser 10, the second semiconductor laser 20, third semiconductor laser
30) the three kinds of different laser beams emitted are respectively through spectroscope (the first spectroscope 12, the second spectroscope 22, third spectroscope
32) it reflects, finally passes through optical shaping system 4 together, laser beam both horizontally and vertically obtains different degrees of
Shaping, the laser beam after shaping focus finally by condenser lens 5 and form (10~15) × (50~70) μm or so
Ellipse hot spot with a tight waist, meanwhile, adjustment semiconductor laser (the first semiconductor laser 10, the second semiconductor laser 20, the
Three semiconductor lasers 30) and fine tuning telescope tube (the first telescope tube 11, the second telescope tube 21, third telescope tube
31), so that semiconductor laser (the first semiconductor laser 10, the second semiconductor laser 20, third semiconductor laser
30) laser beam emitted focuses the ellipse formed hot spot with a tight waist through lens 5, and ellipse hot spot with a tight waist is respectively positioned on cell stream
Dynamic 6 center of room.
Wherein, condenser lens 5 is the glued achromatic lens of a positive light coke, which is effectively reduced difference
The color difference that the laser beam of wavelength is generated when focusing.
Above-mentioned entire light path system is set to inside stream type cell analyzer, since instrument is after long term time use, is equipped with
Semiconductor laser the problems such as will appear power attenuation, such as semiconductor laser, it is therefore necessary to the semiconductor laser more renewed
Device.After the first semiconductor laser 10 more renewed, corresponding first telescope of replaced semiconductor laser need to be only finely tuned
Cylinder 11 may make laser beam to focus the ellipse formed hot spot with a tight waist through achromatism balsaming lens 5 and be located at cell flow chamber 6
On, without adjusting the position of Shaping Module 4 and condenser lens 5, operation adjustment is simple.
Other semiconductor lasers are such as needed to change, such as the second semiconductor laser 20 or third semiconductor 30, operating procedure
It is such as above-mentioned.
The utility model proposes a kind of light path system of telescope tube for cytoanalyze, it is thin which is set to streaming
Born of the same parents' instrument internal reduces fluidic cell based on the optical system, it can be achieved that quick-replaceable laser and adjusting entire light path system
The difficulty of analyzer optical path adjustment, convenient for the after-sales service of technical staff.
The above is only the basic embodiments of the utility model that applicant provides for technical solution, do not represent this reality
The improvement for not having substantive innovative content proposed with novel whole, the technical staff of the industry according to this basic intention
It is regarded as belonging to the scope of the utility model protection.
