Embodiment 1
[0041] see figure 1 , the optical coupling module, whose shaft is in the shape of a cylindrical tube; there is a notch 2 on the top of the optical coupling module along the long axis, see figure 2 ; The length L2 of the notch 2 is between 10-1600mm; the angle α between the two long sides of the notch 2 is between 160° and 210°, see image 3 The two ends of the optical coupling module are the coupling fixing cylinder 3 for fixing the collimator 1, and the coupling fixing cylinder 3 is provided with a through positioning hole 5. The preferred solution is to open a pair of positioning holes 5 in the vertical direction and horizontal direction of the coupling and fixing cylinder 3, and match with adjusting nuts to fine-tune and position the collimator 1 .
Embodiment 2
[0043] see Figure 4 , the optical coupling module, whose shaft is in the shape of a cylindrical tube; there is a notch 2 on the top of the optical coupling module along the long axis, see figure 2 ; The length L2 of the notch 2 is between 10-80mm; the angle α between the two long sides of the notch 2 is between 190° and 210°, see image 3 The two ends of the optical coupling module are the coupling fixing cylinder 3 for fixing the collimator, and the coupling fixing cylinder 3 is provided with through positioning holes 5 . see Figure 5 , Mesh cylinders 6 are provided in the coupling and fixing cylinders 3 . see Figure 6 , insert the collimator 1 covered with the mesh tube 6 on the tube wall into the coupling and fixing tube 3 respectively, after adjusting and coupling the collimator 1 on both sides, and then drip 5 glue from the positioning hole, the glue is in the alignment Under the action of the siphon between the collimator 1, the mesh cylinder 6 and the coupling a...
Embodiment 3
[0046] see Figure 7 , the optical coupling module, whose shaft is in the shape of a cylindrical tube; there is a notch 2 on the top of the optical coupling module along the long axis, see figure 2 ; The length L2 of the notch 2 is between 10-1600mm; the angle α between the two long sides of the notch 2 is between 160° and 210°, see Figure 9 The two ends of the optical coupling module are the coupling fixing cylinder 3 for fixing the collimator, and the coupling fixing cylinder 3 is provided with through positioning holes 5 . see Figure 8 , there is a shallow groove 7 along the long axis direction at the bottom of the rod body of the optical coupling module. Figure 9 .
