Abstract
The utility model relates to a microscopic image focus-change pick-up device. A distance guiding sleeve with a distance guiding slot and a guiding way sleeve provided with two guiding way slots are mutually matched and rotated to drive two lens sets arranged in the guiding way sleeve to conduct conjugated focus-change imaging operation. The distance guiding controlling mode similar to a cam structure is used to enlarge the focus-change range. The operation is simple and rapid.
Description
The utility model relates to a kind of micro-imaging zoom pick device, particularly a kind ofly is used to pick up the optical microscope image, makes it to be used for the zoom pick device that successive image is handled.
At present, be used to pick up the similar device of optical microscope image, general employing is made of second objective lens that direct projection of micro objective or setting are exclusively used in the projection purpose.Along with the successive image treatment technology, especially improving constantly with perfect of Digital Electronic Technique requires the variation that also more and more becomes to the output of optics raw video.The utility model patent CN2290061Y that has authorized has promptly announced a kind of conjugation zoom high magnification photoelectricity multiplying arrangement, to pick up the object lens image by the variable focus lens package of threaded adjusting, is used for follow-up electronic image pickup device and carries out Flame Image Process.But because this device based on screw thread zoom mode, exists zooming range less, the shortcoming that zoom operation is slow.
In order to overcome the defective of zoom lens control device existence in the past, the utility model is announced a kind of micro-imaging zoom pick device at this, adopts the helical pitch control mode of similar cam structure, can improve zooming range greatly, and operation is rapidly succinct.
Concrete structure of the present utility model is as follows.
Micro-imaging zoom pick device described in the utility model has circular main body section, has a lead set from inside to outside, has two helical pitch grooves with cam wheel rim stroke along its body; Described lead set inwardly has a guide rail sleeve, on it longitudinally parallel with axis have two with each self-corresponding guide-track groove of helical pitch groove, the helical pitch groove on their position and the described lead set is crossing to be cooperated; Described lead set is by the guide rail sleeve up and down block bearing and the coaxial fit of guide rail sleeve at two ends, and coaxial rotation relatively; Two lens combination are arranged in the guide rail sleeve, are limited along longitudinal axis moving up and down simultaneously by helical pitch groove and guide-track groove by the guide rod pin; Microscopic imaging device is arranged on the bottom of described guide rail sleeve by lower interface, and is coaxial with guide rail sleeve optics; Other image processors are arranged on the top of described guide rail sleeve by last interface, and are coaxial with guide rail sleeve optics.The track of described helical pitch groove makes the mobile optical conjugate zoom principle that meets of two groups of lens by optical principle design, and the moving of lens combination can change enlargement ratio and can not produce very big total focal plane drift.Here, following lens combination looks like the knot of microcobjective to image on the image planes with last lens combination conjugation, and last lens combination then looks like the knot on the conjugate plane to image on the image processor once more, for example on the CCD plane of camera head.
In view of the above, reached the purpose of this utility model.
Describe a kind of embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the structural principle synoptic diagram of the utility model embodiment.
According to Fig. 1, micro-imaging zoom pick device described in the utility model has circular main body section, has a lead set 1 from inside to outside, has the helical pitch groove 7 and 11 of two cam wheel rim strokes that have along its body; Described lead set 1 inwardly has a guide rail sleeve 2, longitudinally has two and above-mentioned helical pitch groove 7 and 11 each self-corresponding guide-track groove 6 and 10 on it, and their position cooperates with the helical pitch groove 7 and 11 on the described lead set 1 is crossing respectively; Described lead set 1 by guide rail sleeve two ends about in the of 2 block bearing 3 and 12 with guide rail sleeve 2 coaxial fits, and coaxial rotation relatively; Two lens combination 4 and 8 are and are arranged in the guide rail sleeve 2, by guide rod pin 5 and 9 by helical pitch groove 7 and 11 and guide-track groove 6 and 10 limit along longitudinal axis simultaneously and move up and down; The microscopic imaging device (not shown) is by being arranged on guide rail sleeve 1 bottom interface 14 and 1 coaxial connection of lead set, and micro-image picks up by lens combination 8 under port one 5 quilts; Other follow-up image processors are arranged on the top of described guide rail sleeve 1, and by last interface 16 and 1 coaxial connection of guide rail sleeve, the image of last lens combination 4 enters other image processors by upper port 17, for example on the CCD plane of camera head.Described helical pitch groove 7 and 11 track make the mobile optical conjugate zoom principle that meets of two groups of lens 4 and 8 by the optical principle design, and the moving of lens combination can change enlargement ratio and can not produce very big total focal plane drift.Simultaneously, lead set 1 is provided with the driven wheel 13 that is used to make the lead set rotation, can drive along the axis rotation by mechanical hook-up, moves up and down along guide-track groove 6 and 10 respectively thereby drive guide rod pins 5 and 9 by helical pitch groove 7 and 11.
