Description

Multi-functional microscopic imaging apparatus

Technical field

The utility model relates to a kind of light harvesting and electronics is the high power of one and the multi-functional microscopic imaging apparatus of high resolution.

Background technology

Since the microscope invention, increase substantially enlargement ratio and resolution, it is the target that the technician pursues always, but optical microscope generally is 1600 times to the maximum, extreme enlargement factor also can only reach about 2000 times, and when high magnification, not only resolution is difficult to improve, and the depth of field becomes very little, so that can't do desirable observation.Electron microscope has reached the target of high power amplification and resolution, but the electron beam in the electron microscope can cause brokenly ring to many objects of observation, sometimes also must do technical finesses such as metal coating to the object of observation, a high power microtechnic is disclosed so can't observe biological condition of living organism ZL92112064.6, it is that an optical projection microscope and a television camera are linked together, doing one-level with optical microscope amplifies, the optical projection of projection eyepiece is done two utmost points and is amplified, doing three utmost points through photoelectric conversion device again amplifies, can obtain enlargement ratio, 0.3 micron the resolution and the depth of field more than 30 microns up to 12000 times.Because amplifying, its one-level is to use traditional optics to amplify, so when observing, can keep the biologically active of the object of observation.Because secondary and three grades of depth of field of when amplifying one-level being amplified do not exert an influence, so can obtain the very big depth of field in high enlargement ratio.But because it has adopted projection pattern to change enlargement factor, make that between projection eyepiece and the video camera be not directly to be connected, but possess distance, the light-sensitive surface of projection eyepiece and video camera all is exposed in the atmosphere of projection chamber, be subject to the erosion of dust and moisture, influence the quality of imaging, when changing enlargement ratio, it is to do upper and lower mechanical motion by video camera, the inevitable slight vibration that produces of this motion is concerning amplifying more than 10,000 times image, its influence be can not ignore, and must influence image quality.Because the enlargement ratio of projection eyepiece is a fixed value, the image planes of projection eyepiece can not always drop on the target surface of video camera when the upper and lower motion of video camera, thereby cause the image fog on the video monitor, so change multiple at every turn, all must regulate the focus adjusting mechanism on the optical microscope, so that clear picture, it is very inconvenient to operate.

The utility model content

The purpose of this utility model is exactly still to utilize elementary amplification of optics and optical relay mirror, connect and become the technology that times camera lens secondary amplifies and three grades of amplifications of electric video combine, in the high enlargement ratio that keeps prior art, high resolution, the big depth of field with when keeping observing to advantages such as picture virgin states, eliminate projection eyepiece and separate the air erosion that causes with video camera, mechanical shock influences image, and the video camera light-sensitive surface can not remain on the first-class problems of projection eyepiece focus.Should combine closely between optical devices and the photoelectric conversion device, not do relative motion between the two, eliminating trueness error, should be able to continuous zoom, and stop to produce between two parts the problem of focal length dislocation; This good cooperation also should make high power in the change procedure of low power, does not need to focus again, does not also need to adjust significantly the position of condenser and color filter.All devices is combined into an one-piece construction simultaneously, can arbitrarily move to the place of any needs, the complete operation running.

Multi-functional microscopic imaging apparatus described in the utility model is by operator's console, computing machine, optical microscope, the electric control zooming photoelectric conversion device, printer, the one-piece construction that terminal block constitutes, graphoscope, optical microscope, the electric control zooming photoelectric conversion device is placed on the table top of operator's console, computer cabinet and printer are placed in the casing below the operator's console, on the side panel of operator's console, be provided with power interface, electric control zooming photoelectric conversion device interface, video signal input interface, video signal output interface, the monitor signal output interface, telephone line interface, the network interface card interface, the mouse lines interface, each equipment is connected with independent power source wiring board and connecting line by the electric control zooming photoelectric conversion device wiring board that is built in the casing respectively, and and power connection.Elementary multiplying arrangement of the present utility model is an optical microscope; have pedestal and objective table; condenser is arranged below the objective table; condenser is connected with light source chamber; there are object lens the objective table top; three grades are amplified the employing photoelectric commutator; secondary amplifies to be made up of optical relay mirror and continuous zoom camera lens; optical relay mirror and continuous zoom camera lens are bound up; and be fixed together with photoelectric commutator and form the electric control zooming photoelectric conversion device; this device is by a circular outer cylinder; be connected with outer tube bottom; the centre is provided with the chassis of circular hole; be positioned at cylinder; be fixed on support on the chassis by the circular hole base; be connected to each other by screw thread; and be fixed on automatically controlled change times camera lens and photoelectric commutator on the support; be positioned at outside the cylinder; connect with circular hole on the chassis and be fixed on Connection Block on the chassis and objective lens optical axis centering microscopic system; place Connection Block and three order observation ward connection ports; the optics cover glass that the surface is coated with the multilayer anti-reflection film constitutes; video line is connected photoelectric commutator with power lead one end; the other end passes that two holes that have rubber sheath lead to the operator's console control panel on the chassis; photoelectric commutator and electronic change times camera lens are fixed on the support by the vertical shape hole that has the gap on the supporting plate by screw; support is fixed on the chassis by the circular port that has the gap on it by screw, and Connection Block connects with thread forms and optical microscope three order observation ward.The object that is placed on the microscope stage becomes a real image by microcobjective; this real image can amplify by microscope ocular; directly use eye-observation; also can utilize beam splitting system; the real image light beam that microcobjective is become; through the optics cover glass on the Connection Block; enter electronic change times camera lens; imaging on the video camera target surface of photoelectric commutator; by the photoelectricity coupling of photoelectric commutator, light signal is become electric signal again, send into display device (as CRT or LCD) by video line; so just can be at the real-time enlarged image that forms the object on the microscope thing platform on the screen of display device, for Direct observation.
