Description

The optical interface of microimaging analytic system

The utility model relates to the optical interface in a kind of tube of finding a view of microscopical image being delivered to digital camera.

In the prior art, the image computer processing method that collects that adjusts the telescope to one's eyes is: microscope is connected with the CCD camera, micro-image is noted with the mode of simulating signal, utilize the image collection card that analog signal conversion is become digital signal input computer then, carry out treatment of picture and analysis again.It has following shortcoming: (1). and resolution is low, highest resolution 640 * 480 pixels; (2). image needs conversion, and information dropout is big; (3). poor image quality, the colour temperature deviation is big; (4). the graphical analysis result is inaccurate, and error is big; (5). the picture quality of output is poor, can't truly reflect the microworld of microscopically, if the tube of finding a view of microscope and digital camera directly is connected then digital camera can't obtain image.

The purpose of this utility model is to provide a kind of and the optical interface of microscopical image transfer to the high-resolution digital camera can be made and calculate the digital signal that function is directly accepted digital camera.

The technical solution of the utility model is: a kind of optical interface of microimaging analytic system, and the bottom of interface tube is connected with the oral area of microscopical microscope tube, and the top of described interface tube is connected with the oral area of digital camera lens barrel; The inner chamber of described interface tube is provided with the school apart from inner lens cone, and described school is connected with the inner thread of lens barrel outside the distance of school apart from the outer wall of inner lens cone, and described school is provided with convex lens apart from inner lens cone, and described school is provided with plano-convex lens apart from outer lens barrel.

The utility model compared with prior art has following advantage:

Owing to the optical signalling that optical interface can be obtained with microscope is delivered in the tube of finding a view of digital camera through two convex lens, therefore digital camera can directly be converted to light signal digital signal and note, digital camera can be connected with computing machine then and carry out graphical analysis, its resolution is up to mega pixel to ten million pixel, image need not conversion, therefore information is not lost, and picture quality is good.

The utility model will be further described below in conjunction with drawings and Examples:
