| titleOfInvention | An optical collimating system |
| abstract | An embodiment of the present invention discloses an optical collimating system for collimating a beam with a preset numerical aperture and a preset wavelength. The foregoing optical collimating system includes a first plano-convex lens and a first bend that are sequentially positioned on the side of the object plane Convex lens, second meniscus lens, third meniscus lens, and first biconvex lens; the power of the first plano-convex lens is D1, and the power of the first meniscus lens is D2, The power of the second meniscus convex lens is D3, the power of the third meniscus convex lens is D4, and the power of the first biconvex lens is D5; where, D1>0, D2>0, D3 >0, D4>0, D5>0, and min{D3, D4, D5} max{D3, D4, D5}; min{D3, D4, D5} represents the minimum value among D3, D4, and D5, and max{D3, D4, D5} represents the maximum value among D3, D4, and D5. Reasonably set the shape and power of each convex lens between the object surface and the image surface to ensure that the optical collimation system has good collimation effect for the beam with the preset numerical aperture and the preset wavelength. |
