Abstract
The present invention provides the imaging converting system of a kind of flat field scanning lens working face and surgical operation microscope working face, it is characterised in that：It includes microscope and scanning lens, the working face that being provided between the two is used for scanning scanning lens is transformed into the imaging matching camera lens of microscopical first imaging surface, by the design for being imaged matching camera lens, collimated light beam from working face through flat field scanning lens is imaged, and expand light beam cone angle, the aperture of binocular can be covered on micro objective.
Description
Technical field
The invention belongs to optical technical field, applied to industries such as industry, detection, medical treatment, for by flat field scanning lens
Working face be transferred to the working face of surgical operation microscope, user of service is observed the work of scanning lens by microscope
Face.
Background technology
Laser is often used in Laser Processing or laser medicine industry to be scanned target face, while needing work people
Member carries out Real Time Observation or monitoring to working face.This is accomplished by that light path system is designed to ensure laser optical path and imaging
Road matching is unified.
Last focus on is carried out to laser in general laser light path system using simple lens again by 45 degree of speculum reflections to make
For working face, 45 degree of mirrors of visible light-transmissive on working face are received by CCD, are just formed the picture of working face, are passed through computer screen
Curtain can directly observe the real-time condition of working face, as shown in Figure 1.
In accurate medical operating, the flat field scanning lens that big NA values are used in laser optical path is focused, into
Observed, it is therefore desirable to individually designed to imaging optical path progress, made as much as possible as using body formula surgical operation microscope in light path
Imaging effect is accomplished most preferably.
And operated using conventional technology, then do not possess real-time, it is necessary to which being observed frequently, influences operation
Fluency.
