Abstract
The utility model relates to a multi-function micro-projection instrument. The utility model is composed of a light source, a collecting mirror, a microscope, reflectors, a projection screen, etc. The utility model is divided into an operation chamber and a projection chamber. The light source (2), the collecting mirror (3), the microscope (4), the reflector (6) and a fan (1) are positioned in the operation chamber. The reflectors (7) and (8) and the projection screen are positioned in the projection chamber. The light source irradiates a sample on a slide glass sheet through the collecting mirror, and the first imaging is formed on an eye lens through an objective lens; then the light pass through the reflective light path which is formed by the reflectors (6), (7) and (8), and finally, the second imaging is formed on the frosting projection screen. The utility model has the advantages of simple structure, small light source power and low cost. The utility model can be used for directly carrying out micro-drawing and photography, or can also be used for people's simultaneous observation and research.
Description
The utility model belongs to field of optical applications, is specifically related to a kind of multi-functional microscopic projector, is applicable to fields such as scientific research, teaching, inspection body.
Continuous development along with science and technology, people are engaged in scientific research, teaching, check in work such as data collection, record experimental result and exchange of technology, the chance that need utilize microscope to draw, photograph is more and more, but the structure of present existing microscopic projector is giant-screen or adds an observation the small screen, its shortcoming is complex structure, costs an arm and a leg, and can not be used for drawing; Other has a kind of vertical type plotting apparatus that can be used to carry out micro-drawing, and this structure is because of the restriction of light channel structure, and microscope is placed on subaerial worktable bottom, operation, observation inconvenience, unfavorable applying.
The purpose of this utility model provide a kind of simple in structure, cost is low, easy to operate, can carry out micro-drawing, photography and carry out the multi-functional microscopic projector of observational study simultaneously for many people.
The utility model is made up of light source (2), condenser (3), microscope (4), catoptron (6), projection screen (9) etc., divide operation room and projection chamber, light source (2), condenser (3), microscope (4), catoptron (6), fan (1) place in the operation room, catoptron (7), (8) and projection screen place in the projection chamber, light source shines sample on the microslide through condenser, by object lens imaging for the first time on eyepiece, pass through the reflected light path of catoptron (6), (7), (8) composition again, imaging for the second time on the ground glass projection screen at last.
The utility model has the advantages that simple in structurely, light source power is little, is got final product by the fan heat radiation, and production cost is low; Microscope is at normal operating position, and projection screen is fixed on the projection chamber front, has angle with surface level, promptly is convenient to operation and observation, can directly carry out micro-drawing, photography again or supply many people observational studies simultaneously; The figure of imaging is clear on the projection screen, fidelity good,
Below in conjunction with drawings and Examples structure of the present utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model contour structures synoptic diagram.
Fig. 3 is the angular relationship synoptic diagram of the utility model projection screen and catoptron.
By accompanying drawing as can be known, the utility model is made up of projection chamber and operation room, isolate by shadow shield in the middle of two Room, its structure comprises light source (2), condenser (3), microscope (4), catoptron (6), (7), (8), projection screen (9) and fan (1) etc., the light source (2) that is placed in microscope (4) bottom is 12V, the quartz bulb of 50-100W, its side is provided with a small fan (1) and dispels the heat, light source (2) shines on the sample through condenser (3), object lens and eyepiece imaging for the first time through microscope (4), make the straight steering reflection mirror of light path (7) (horizontal by miter angle) by catoptron (6) (horizontal by miter angle), catoptron (7) again the image vertical reflection to catoptron (8) (horizontal by 30 the degree angles), reflex to ground glass projection screen (9) (horizontal by 60 degree angles) at last and go up imaging for the second time, projection screen (9) places the projection chamber front as shown in Figure 2, have angle with surface level, its angle can be arranged between the 30-90 degree, so that draw, the angle of the projection screen that present embodiment is (9) is 60 degree, projection screen is of a size of 20 * 20CM, be convenient to place template, and optical axis and observer's sight line are coincide, be convenient to draw and observe, optical axis is vertical with the projection screen plane, make image not by shape, carry out the adjusting of focal length and brightness by two focus regulators of microscopical thickness and light source potentiometer, make image more clear, correspondingly the angle of catoptron (8) can be arranged between the 15-45 degree, the angle of projection screen (9) and surface level is catoptron (8) and surface level angle 2 times, so that optical axis direction is vertical with the projection screen plane.
