The utility model relatively has following advantage with the array collimation device that adopts array fibre head and array lens:
(1) the relative broad of spacing tolerance between the array fibre head optical fiber is decided according to the size of different outgoing hot spots, can reach more than 1 micron even 10 microns.
(2) adopt single lens to reduce the difficulty that lens arra is made, cost is relatively low.
The utility model array collimation device relatively has following advantage with the array collimation device that adopts single collimating apparatus to be assembled into:
(1) spacing between the outgoing beam can be accomplished smallerly, can accomplish below the 1mm.
(2) the mount difficulty is relatively low, and lens are to regulate one by one to bond on the glass plate.
