Description
Technical field
The utility model relates to optical instrument, especially a kind of conversion equipment that is used for microscopical bright and dark field condenser.
Background technology
At present, bright-field condenser and dark field condenser are equipped with as microscopical auxiliary.During use, bright-field condenser or dark field condenser carrier can be located on the adjusting centre frame of microscope light path, be the center then with the microscopes optical axis, regulates bright-field condenser or dark field condenser to concentric with optical axis, can use.The condenser center adjustment requires high, and center adjustment is operated tens of mark consuming time, and whenever changes a condenser and must regulate a subcenter, has influenced work efficiency, also makes troubles to use.
Summary of the invention
The purpose of this utility model is at the above-mentioned bright and dark field condenser loaded down with trivial details time-consuming defective of conversion operations in actual use, and a kind of regulation free type microscope bright and dark field conversion equipment is provided.
Regulation free type microscope of the present utility model is bright, the dark field conversion equipment comprises: bright-field condenser and dark field condenser, according to the pedestal that has the dovetail grooved rail between microscopical seat surface and the levelling centre frame low level apart from design one, the bottom surface of pedestal is the structure that can cooperate the location with microscopical seat surface, be provided with a slide block that can move along grooved rail in the grooved rail of pedestal, offer circular hole on the slide block, for bright-field condenser is installed, slide block is provided with the control lever that it is moved in grooved rail, be provided with the position-limit mechanism that to determine that slide block moves into place between slide block and the grooved rail, the dark field condenser is arranged on the grooved rail face of pedestal, the cone segments of dark field condenser is plugged in the grooved rail, the dark field condenser can move along grooved rail on pedestal, and the end of grooved rail is provided with and can stops dark field condenser or slide block to move the baffle plate that takes off grooved rail respectively.
Regulation free type microscope of the present utility model is bright, the dark field conversion equipment dexterously microscope is joined bright-field condenser commonly used and dark field light microscopic be arranged on one with used microscope seat surface to the pedestal of aligning centre frame coupling, because the position of set dovetail grooved rail is designed according to the microscopes optical axis center on the pedestal, so, as long as being separately positioned on the dark field condenser of dovetail grooved rail upper groove surface and the slide block that bright-field condenser is housed of grooved rail bottom moves to, can make it concentric with microscopes optical axis respectively, constitute microscopical bright field observing system or dark field observing system with the end light condenser on the microscope pedestal, realize the quick conversion of different view modes.It is easy to operate, and the time has been saved in the optical axis center accurate positioning, has improved efficient.This apparatus structure is simple, and is scientific and reasonable, is applicable to the microscope of disposable type.
Description of drawings
Fig. 1 is the structural representation of regulation free type microscope bright and dark field conversion equipment;
Fig. 2 is a regulation free type microscope bright and dark field conversion equipment shown in Figure 1 left side TV structure synoptic diagram.
Embodiment
The regulation free type microscope is bright, the dark field conversion equipment has one according to 13 of microscopical pedestals and transfer between the levelling centre frame 14 of low level apart from the pedestal 1 that designs, the last plane of pedestal 1 is parallel with microscopical levelling centre frame 14, the baseplane of pedestal 1 is provided with the groove 3 that can cooperate the location with the microscope pedestal, have the dovetail grooved rail 2 that front and back connect on the pedestal 1, one slide block 4 that can move along grooved rail is set in the grooved rail 2, offer the circular hole 6 that is used to install bright-field condenser 5 on the slide block 4, one end of slide block 4 connects a control lever 7, position-limit mechanism 8 between slide block 4 and the grooved rail 2 is made of the locating piece 8.1 of slide block bottom surface and the limited block 8.2 of grooved rail 2 one bottom faces, locating piece 8.2 is that magnetic is glad, and limited block 8.2 is the irony piece.Dark field condenser 9 is set up on the last plane of pedestal 1, the cone segments 10 of the poly-mirror 9 of dark field is inserted grooved rail 2, dark field condenser 9 can move at upper edge, pedestal 1 plane grooved rail 2, and the end of grooved rail 2 is provided with the baffle plate 11,12 that can stop dark field condenser 9 and slide block 4 to move respectively to take off grooved rail 2.
The utility model regulation free type microscope is bright, the using method of dark field conversion equipment is: be fixed on microscopical pedestal 13 planes with the pedestal 1 of screw with device, because the height of pedestal 1 designs according to distance between 13 of microscopical pedestals and the levelling centre frame 14, pedestal 1 plane just in time is connected mutually with the levelling centre frame 14 of low level is concordant, so the dark field condenser 9 that is arranged on the pedestal 1 can push by the grooved rail 2 of pedestal 1 on the levelling centre frame 14, after regulating, can constitute the dark field observing system with the end light condenser 15 on the microscope pedestal 13.When carrying out the bright field when observing, only need to reduce to concordant with 1 of pedestal at the dark field condenser 9 on the levelling centre frame 14, just dark field condenser 9 can be withdrawed from and moves in the grooved rail 2 of pedestal 1 from levelling centre frame 14.At this moment, can push the working position by operating straight 7 slide blocks 4 that will be arranged in the grooved rail 2, the limited block 8.1 of grooved rail 2 bottom surfaces cooperates with the locating piece 8.2 of slider bottom, can guarantee that slide block 4 moves into place, promptly guaranteed to be arranged on the slide block 4 bright-field condenser 5 with come poly-mirror 15 optical axises of light concentric at the bottom of the microscope, constitute the bright field observing system.After finishing the bright field observation, only need pulling pull bar 7, make slide block 4 be retracted into grooved rail 2 and get final product.Operation has like this realized carrying out fast the purpose that the microscope bright and dark field is changed.
The position-limit mechanism 8 that the slide block 4 of the utility model regulation free type microscope bright and dark field conversion equipment moves into place in grooved rail 2 also can adopt the elastic steel ball stop means, promptly spring steel ball is set, the shrinkage pool that can be absorbed in steel ball is set in the bottom surface of slide block 4 in grooved rail 2 baseplanes.When slide block 4 moves into place, the shrinkage pool that steel ball is gone into the slide block bottom surface in the pressure sinkage of spring, the location of realizing slide block 4.
