Description
Technical field
The utility model relates to a kind of microscopy imaging system, specifically a kind of double-view field combined optical imaging system.
Background technology
Along with world economic integration technical progress and development, constantly progressive and improve along with domestic manufacturing process, simultaneously also along with client to the quality of product and accuracy requirement also more and more higher.The complexity of workpiece is also more and more higher, and batch production quantity is also increasing, requires that the quantity detected is also increasing.But existing imaging lens field range is little, for wanting measuring position Search and Orientation difficulty beyond field range, thus make to measure efficiency and reduce greatly, in the face of unexpectedly striving so strong society, raising the efficiency is that all clients compel to expect, the easy eyes of another Long-Time Service are uncomfortable.
Utility model content
The purpose of this utility model is to provide a kind of microscopy imaging system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of double-view field combined optical imaging system, comprise main imaging body, main imaging system CCD imaging surface, object plane and auxiliary imaging system CCD imaging surface, between described main imaging system CCD imaging surface and object plane, spectroscope is installed, between spectroscope and object plane, green filter is housed, between object plane and auxiliary imaging system CCD imaging surface, reflective mirror is installed, between reflective mirror and auxiliary imaging system CCD imaging surface, large market associated image mirror group and aperture diaphragm is installed; Described spectroscope is parallel with reflective mirror, and spectroscope and angle at 45 ° between reflective mirror and surface level.
Compared with prior art, the beneficial effects of the utility model are: more comfortable during use, production cost is low, can carry out imaging in a big way to the object of observation, can conveniently search out target observations body and position, improve the efficiency of measurement.
Accompanying drawing explanation
Fig. 1 is the structural representation of comfortable microscope auxiliary imaging system.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1, a kind of double-view field combined optical imaging system, comprise main imaging body 10, main imaging system CCD imaging surface 2, object plane 3 and auxiliary imaging system CCD imaging surface 4, between described main imaging system CCD imaging surface 2 and object plane 3, spectroscope 5 is installed, green filter 1 is housed between spectroscope 5 and object plane 3, between object plane 3 and auxiliary imaging system CCD imaging surface 4, reflective mirror 6 is installed, large market associated image mirror group 8 and aperture diaphragm 7 are installed between reflective mirror 6 and auxiliary imaging system CCD imaging surface 4; Described spectroscope 5 is parallel with reflective mirror 6, and spectroscope 5 and angle at 45 ° between reflective mirror 6 and surface level.Use of the present utility model time, by object emitted light after filtration light microscopic 1 filter, be divided into two-way to advance after rear arrival spectroscope 5, wherein throw light enters main imaging body 10, then imaging on its CCD front; Reflection ray is imaged on its CCD front through auxiliary imaging system CCD imaging surface 4, and auxiliary imaging system CCD imaging surface 4 plays and dwindles into picture (namely taking a picture) effect.According to this apparatus function requirement, the second camera mirror of auxiliary imaging system CCD imaging surface 4 can be fixed multiplying power imaging, also the imaging of certain little zoom scope can be had, so, this device just can obtain the areas imaging more much bigger than main optical path, same target can be observed by two-way CCD imaging signal during user operation, for the object observing be positioned at outside main optical path field range, can by the function fast finding of servicing unit and location, then move within the scope of main body light path the target observations carried out needed for user fast, thus realize the purpose of this utility model.
Principle of work of the present utility model is: second camera mirror group and main body imaging optical path share object plane, their respective focal lengths not etc.: second camera mirror group focal length is much smaller than the focal length of main body imaging optical path, and its conjugate distance is also short out than key light.Namely the light that sends of same object is by after two groups of imaging lens of different focal, be imaged in the CCD image planes of its correspondence separately, focal length short second camera mirror group areas imaging be greater than the long main optical path areas imaging of focal length, with reference to accompanying drawing, if main optical path object distance L1, image distance L2, enlargement ratio M, homologue surface imaging radius R 1, image planes radius R 2; Second camera light path object distance L1 ', image distance L2 ', enlargement ratio M ', homologue surface imaging radius R 1 ', image planes radius R 2 '
Due to M=L2/L1=R2/R1, M '=L2 '/L1 '=R2 '/R1 '
According to the requirement to image relation, there is L1 < L2, L1 ' > L2 ', then M > M '
I.e. R2/R1 > R2 '/R1 '
When main and auxiliary light path adopts the CCD of same size size to carry out image planes collection, then there is R2=R2 '
I.e. 1/R1 > 1/R1 ', then R1 ' > R1, illustrate when the multiplying power of associated image light path is less than the multiplying power of main optical path, when carrying out image planes with the CCD of same size size and gathering, the areas imaging that associated image light path collects is greater than the areas imaging that main optical path can collect.So realize the imaging function on a large scale of auxiliary optical path.
Wherein, the installation site of associated image mirror group is not fixed, according to the picture element specific requirement of this accessory, the factors such as topology layout, placement can not be concentrated in auxiliary lens position, such as the assembling and dismantling of associated image mirror mirror are divided into two groups, wherein one group be positioned over spectroscope after, before another group is positioned over CCD.No matter how layout, does not affect the multiplying power size spectrum of auxiliary optical path and main optical path, auxiliary optical path and main optical path non-confocal, and should be common object plane and different object distances, confocal concept refers to that directional light is through after two mirror groups, and focal position is identical.
CCD, English full name: Charge Coupled Device, Chinese full name: charge coupled cell.Also can be described as ccd image sensor.It uses a kind of semiconductor material of ISO to make, and light can be transformed into electric charge, then converts charge signal to digital signal by analog to digital converter chip, and digital signal is sent to image computer just being formed and gathers after overcompression process
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
