Abstract
The utility model discloses a video display focal degree instrument, which comprise a base, an upright post, an image pickup instrument and a video display mechanism, wherein the upright post is arranged on the base, the video display mechanism comprises a display screen and a scale value display window, the display screen is positioned at the top end of the upright post, the scale value display window is positioned on a side frame of the display screen, and the image pickup instrument is positioned under the display screen. According to the a video display focal degree instrument adopting such structure, the video display is adopted, the scale value display window directly displays test results, multiple test persons can jointly observe the scale value display window, the scale value can be reduced by several times, the test result differences caused by eyesight differences of the test persons are avoided, the clearness and the accuracy of the test results can be ensured, in addition, a lens is horizontally placed, and the operation is convenient.
Description
Technical field
The utility model relates to optical instrument, relates in particular to a kind of video and shows the focal power appearance.
Background technology,
The focal power appearance is used for measuring concave-sphere, post mirror diopter, post mirror axle position, prism degree and the prism base direction of eyeglass, and can be to optical centre, post mirror axle position and the post mirror substrate direction stamp of eyeglass.In the prior art, measure the lensmeter of eyeglass focal power, for the ease of on eyepiece, observing; The column of lensmeter and the axis of optical facilities all tilt; During operation, with eyes eyepiece is observed, simultaneously vernier by a tester; After fine setting finished, the numerical value current to index dial carried out reading.Because of tester's eyesight there are differences, so different tester's observationss possibly there are differences, and scale value is bigger in addition, and reading difficult is with accurately.Also do not have at present such video to show the focal power appearance, the test result difference that it can avoid tester's eyesight difference to cause can guarantee that test result is clear accurately.
The utility model content
The utility model technical matters to be solved is: provide a kind of video to show the focal power appearance, this kind video shows the test result difference that the focal power appearance can avoid tester's eyesight difference to cause, and can guarantee that test result is clear accurately.
Solve this technical problem; The technical scheme of the utility model is: a kind of video shows the focal power appearance; It comprises column, video camera and the video indication mechanism of base, base top, and described video indication mechanism comprises display screen and scale value display window, and described display location is in the top of column; Described scale value display window is positioned on the frame of display screen, and described video camera is positioned at the below of display screen.
The center line of described video camera is a perpendicular line.
The middle part of described column is provided with light source and reflector, and described reflector is positioned at the below of light source.
The below of described video camera is provided with compensation rib device.
The utility model video shows that the focal power appearance adopts such structure, adopts video to show that the scale value display window directly shows test results; Several testers can observe jointly; Scale value can reduce several times, and the test result difference of avoiding tester's eyesight difference to cause can guarantee that test result is clear accurately; And the eyeglass level is put, and is easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model video is shown the explanation in further detail of focal power appearance do;
Fig. 1 shows focal power appearance structural representation for the utility model video;
Among Fig. 1,1, base, 2, regulate button, 3, column, 4, light source, 5, compensation rib device, 6, video camera, 7, display screen, 8, the scale value display window; 9, eyeglass folder, 10, reflector, 11, collimator objective, 12, power knob.
Embodiment
As shown in Figure 1; Video shows that the focal power appearance comprises column 3, light source 4, compensation rib device 5, video camera 6, eyeglass folder 9, reflector 10, collimator objective 11 and the video indication mechanism of base 1, base 1 top; The video indication mechanism comprises display screen 7 and scale value display window 8, and display screen 7 is positioned at the top of column 3, and scale value display window 8 is positioned on the frame of display screen 7; Video camera 6 is positioned at the below of display screen 7, and the center line of video camera 6 is a perpendicular line.Video camera 6 belows have compensation rib device 5; Collimator objective 11 is installed in the bottom of column 3; Between collimator objective 11 and the compensation rib device 5 eyeglass folder 9 is housed, the middle part of column 3 has light source 4 and reflector 10, and reflector 10 is positioned at the below of light source 4; Column 3 lower side are equipped with regulates button 2, and power knob 12 is positioned on the base 1.Such structure is used the optical focus principle, inartificial programming; The employing video shows that the scale value display window directly shows the eyeglass vertex lens power, and several testers can observe jointly; Scale value can reduce several times, and the test result difference of avoiding tester's eyesight difference to cause can guarantee that test result is clear accurately; And the eyeglass level is put, and is easy to operate.
