F at, compound camera lens has been divided into a and b by center bore and annular aperture part of the diaphragm to compound camera lens by beam of laser
The laser in two regions, the region a aperture portion is collimated into the La of distant place, forms hot spot, and the region b aperture portion is in defocus
State dissipates the laser in the region b, and Lb at a distance goes out to form required hot spot, real by adjusting the position of laser source
The adjusting of existing different collimating status, and then realize close, distant location hot spot control respectively.
The utility model has the advantages that the present invention uses the compound camera lens being combined by the first positive lens and lens ring, so that composite mirrors
Head center and outer ring portion have different focal powers, thereby realize and have merged different focal powers in same original part.
And compound camera lens can there are many combinations, the looping pit that can be lens ring to be embedded in the second positive lens, but also
Centre bore is different with the focal power of outer ring portion；The quantity that lens ring can also be increased according to actual needs, first annular
Mirror one end at laser source is equipped with the second lens ring, and the outer diameter of the second lens ring is greater than the outer of first annular lens
Diameter, such combination make have different focal lengths within the scope of different annular apertures, and the second lens ring looping pit
The center and laser axis of center and first annular lens looping pit are in the same horizontal line；Either utilize different holes
There is diameter range inner region different face types to realize the compound of more focal powers, and the compound camera lens in the invention can be according to difference
Distance then laser beam light at different distances is realized by the combination of different focal powers using different combinations
The control respectively of spot size.
