Facula continuously adjustable swashs optical adapter and eye ground laser treatment unit

The utility model is suitable for a medical equipment technical field provides a facula continuously adjustable sharp optical adapter, including input optic fibre, be equipped with in light path in its output and be used for the imaging lens group of laser formation of image for the first facula of flat top distribution for carry out the collimating mirror of collimation to the light beam, be used for focusing on the focusing mirror that forms the second facula to beam, the object space coke side of collimating mirror with first facula coincidence, imaging lens group and collimating mirror can be along the direction removal that is on a parallel with the light path so that second facula continuously adjustable. The utility model discloses an imaging lens group distributes the laser formation of image for the flat top first facula, the second facula is unanimous basically with the energy distribution state of first facula, therefore its facula energy is even, the edge is clear sharp keen, the size is true and reliable, and treatment obviously improves, linkage through imaging lens group and collimating mirror realizes the 2nd spot size's continuous variation, is more convenient for that it is regional to change the treatment according to the actual pathological change circumstances, promotes treatment and efficiency.
