Drive the focal length between biconcave lens 3 of biconvex lens 1.
Detailed, the biconvex lens 1 is fixed in the first mounting seat 2.The upper end of first mounting seat 2 has movement
Mechanism 21, lower end has second limited block 22, and the limited block 22 of travel mechanism 21 and second is to be located at phase in mounting seat 2
To both sides.Wherein biconcave lens 3 is fixed, and can specifically be fixed on the output end of a laser chip.Or it is logical
A mounting seat is crossed to be fixed.The technical scheme of the present embodiment, a mounting seat is fixed on by biconcave lens 3 for convenience of description
On.
Wherein, first mounting seat 2 is threadedly coupled a micromotion mechanism 4, and the micromotion mechanism 4 can drive institute when rotating
The first mounting seat 2 is stated to move back and forth.I.e. in the present embodiment, micromotion mechanism 4 realizes driving by being connected with travel mechanism 21.
Reference picture 1, the micromotion mechanism 4 includes screw mandrel 41 and the micromover 42 that be connected with the screw mandrel 41, the screw mandrel 41 and
The travel mechanism 21 is threadedly coupled, and drives the travel mechanism 21 to move.In this programme, micromover 42 is using a stepping electricity
Machine.In order to realize the fixation of screw mandrel 41 and micromover 42, micromotion mechanism 4 should also include a fixed seat 43, and the fixed seat 43 is wrapped
Include a bottom plate 431 and the baffle plate 432 positioned at the two ends of bottom plate 431, wherein screw mandrel 41 be just rotatably installed in two baffle plates 432 it
