The utility model discloses a kind of double-colored spot light-source structures, including the first light source, first collector lens, Amici prism, the second collector lens, second light source set gradually from left to right, parabolic mirror is equipped with above the Amici prism, lower section is equipped with lens group.The utility model provides the stable double-colored spot light-source structure of a kind of simple structure and reasonable design, performance, the structure provides proper double-colored compound point light source for slit-lamp microscope Kohler illumination system, uniform hot spot illumination can be obtained with this configuration, clearer image can not only be obtained, and infrared image can also be obtained.
Description
Technical field
The utility model relates to microscope illumination technical fields, and in particular to a kind of double-colored spot light-source structure.
Background technique
Slit-lamp microscope is the essential important instrument of eye examination, in general, slit-lamp microscope is by lighting system
It is formed with binocular microscope, the lesion that it can not only make table shallow is observed fully aware of, and adjustable focus and light source are wide
It is narrow, it is made into " optic section ", show the lesion of deep tissue can also clearly.
Current slit-lamp microscope illumination generallys use Kohler illumination, and point light source required for Kohler illumination is usually adopted
It is replaced with monochromatic light bulb, light bulb is not point light source as light source, and only the point light source in general approximate terms, passes through this
Kind mode Kohler illumination hot spot obtained will have a large amount of stray lights, and hot spot uniformity is also very poor, and is monochromatic source, passes through
This illumination reflection image definition obtained is necessarily impacted, cannot also obtain infrared image, to solve the above problems, this
Utility model proposes a kind of double-colored spot light-source structure.
Utility model content
In view of the shortcomings of the prior art, the utility model provides stable double-colored of a kind of simple structure and reasonable design, performance
Spot light-source structure, the structure provide proper double-colored spot light for slit-lamp microscope Kohler illumination system
Source can obtain uniform hot spot illumination with this configuration, can not only obtain clearer image, and can also obtain infrared
Image.
To realize purpose of utility model, the utility model uses following technical scheme:
A kind of double-colored spot light-source structure, including set gradually from left to right first light source, first collector lens, point
Light prism, the second collector lens, second light source, the Amici prism top are equipped with parabolic mirror, and lower section is equipped with lens group.
Preferably, the first light source is halogen bulb.
Preferably, the second light source is 850LED lamp.
Preferably, the asphericity coefficient K=- 1 of the parabolic mirror.
Preferably, the first collector lens and the second collector lens are made of K9 glass.
The beneficial effects of the utility model are: the utility model provides a kind of simple structure and reasonable design, performance is stablized
Double-colored spot light-source structure, including double light sources, 2 collector lenses, Amici prism and parabolic mirror, which is to split
Gap lamp microscope Kohler illumination system provides proper double-colored compound point light source, can obtain with this configuration uniform
Hot spot illumination, can not only obtain clearer image, and can also obtain infrared image.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the double-colored Kohler illumination system's structural schematic diagram for including double-colored spot light-source structure；
In the figures above: 1, first light source；2, first collector lens；3, Amici prism；4, the second collector lens；5, second
Light source；6, parabolic mirror；7, lens group.
Specific embodiment
The utility model is further described by specific embodiment with reference to the accompanying drawing.
As shown in Figure 1 and Figure 2, a kind of double-colored spot light-source structure, including set gradually from left to right first light source 1,
It is anti-to be equipped with paraboloid above the Amici prism 3 for first collector lens 2, Amici prism 3, the second collector lens 4, second light source 5
Mirror 6 is penetrated, lower section is equipped with lens group 7, and the first light source 1 is halogen bulb, and the second light source 5 is 850LED lamp, the throwing
The asphericity coefficient K of parabolic mirror 6=- 1, the first collector lens 2 and the second collector lens 4 are made of K9 glass.
Working principle:
First light source transmitting light converges to the P point of Amici prism through first collector lens, and second light source emits infrared light
Line is converted into collimated light beam through the second collector lens, parabolic mirror is reflexed to by Amici prism, through parabolic mirror
The P point of Amici prism is converged to, the luminous ray of first light source transmitting at this time and the infrared light of second light source transmitting converge to
Same P point forms double-colored compound point light source, for the Kohler illumination system of slit-lamp microscope lighting part provides stringent meaning
Point light source in justice and be double-colored.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, the utility model can be used on similar product, and any those skilled in the art is in the field of the utility model, institute
The changes or modifications of work all cover among the scope of the patents of the utility model.
