The content of the invention
The object of the present invention is to provide a kind of variable mating plate thickness and the mating plate of length to illuminate microscope illumination light path system,
In the case where being changed without mating plate lighting system, the observation to the biological specimen in the range of certain size is realized.
To achieve the above object of the invention, the technical scheme is that:
A kind of variable mating plate thickness and the mating plate of length illuminate microscopical lighting system, are included successively by thing side to image side
Along optical axis arrangement:Laser light source, without burnt zoom beam-expanding system, cylindrical lens, microcobjective, wherein described expand without burnt zoom
Beam system for full spherical mirror four constituent element mechanical compensations without burnt zoom beam-expanding system, the four constituent element mechanical compensations are without burnt zoom
Beam-expanding system fixes group, zoom group, compensation group and fixes group afterwards before being followed successively by from thing side to image side, Jiao of the preceding fixed group
Away from for just, the focal length of zoom group be bear, the focal length of compensation group be bear, the focal length of fixed group is just afterwards;Sent out from the laser light source
The light gone out is used to the collimated light beam being modulated to column by first fixed group without burnt zoom beam-expanding system, the cylindrical lens
After being imaged at the front focus of fixed group, the light from rear fixed group outgoing is collimated light beam, is passed through for surface wave, zoom group and compensation group
It is compressed in by the cylindrical lens that rotation axis is rotated by 90 ° of optical axis at postposition microcobjective front focus, finally by the micro- thing of aplanasia
Mirror eliminates the spherical aberration introduced without burnt zoom beam-expanding system and cylindrical lens, obtains required mating plate.

Several animal and plant cells and embryo's sample;In addition shoot laser beam bore is 1-10mm after without burnt zoom beam-expanding system, also
Can guarantee that mating plate width and light intensity in rational scope:If shoot laser beam bore is too small, obtained mating plate width is small, can
Sample range for observation also diminishes, if shoot laser beam bore is excessive, can increase the size of rear end cylindrical lens, and meeting
Reduce the light intensity in mating plate width range.
The zoom ratio of no burnt zoom beam-expanding system is 10 times.That brings has the technical effect that:10 times are selected to expand without burnt zoom
Beam system both can obtain required mating plate thickness and length in the case where being not required multistage to expand, and reduce whole system
Design difficulty.In addition, 10 times of beam-expanding systems also cause the rear part lens hole footpath of system to be unlikely to excessive, and increase processing and
The difficulty of adjustment.
Preferable cylindrical lens are plano-convex cylindrical lens in above-mentioned technical proposal.The incident light that laser light source is sent passes through to be become without Jiao
After times beam-expanding system then vertical incidence modulates light in blocks, the skill brought to plano-convex cylindrical lens by the pillar face of plano-convex cylindrical lens
Art effect is:1st, circular light spot is compressed into wire hot spot;2nd, system spherical aberration is reduced;3rd, plano-convex cylindrical lens compared to biconvex or
The adjustment easy to process of person's concave-concave cylindrical lens.
In specific above-mentioned technical proposal:The image-side numerical aperture NA=0.25 of aplanasia microcobjective, back work distance from
More than or equal to 7mm.The setting of image-side numerical aperture NA=0.25 is effectively guaranteed luminous flux, difference is expanded the mating plate than under
It is attained by due layer and cuts ability;Back work distance can not only ensure sample placement space from the setting more than or equal to 7mm, but also not
Whole system can be made to seem lengthy.
To sum up, the order passed through in the technical program by light, the light respectively sent from laser light source, by four constituent elements
Mechanical compensation realizes the change of outgoing laser beams bore without burnt zoom beam-expanding system, then is revolved by one by rotation axis of optical axis
Turn 90 ° of cylindrical lens and form a kind of lamella light, the lamella light formed again by an aplanasia microcobjective go abatement due to
The spherical aberration that no burnt zoom beam-expanding system and cylindrical lens produce;Along optical axis direction, incident laser enters without burnt zoom beam-expanding system
It is later collimated, then it is compressed in its focal plane by cylindrical lens.Microcobjective is placed on cylindrical lens post-compensation system spherical aberration,
So that the light intensity of whole mating plate keeps uniformity.Lighting system is except a cylindrical lens are employed, its lap is all sphere, this causes
