[0041] first reference figure 1 , the optical system includes: a light source 100 , a first beam changing device 200 , a diverging device 300 , a first converging device 400 , a moving device 500 and a scanning format 600 .
[0042] The light source 100 emits a light beam 101 , and the light beam 101 sequentially passes through the first light beam changing device 200 , the diverging device 300 , and the first converging device 400 to reach the scanning format 600 .
[0043] In this embodiment, the moving device 500 is respectively connected to the first beam changing device 200, the diverging device 300 and the first converging device 400, and is used to control the first beam changing device 200, the diverging device 300 and the first converging device 400 movement in the light path.
[0044] refer to figure 2 ,pass figure 1 The middle moving device 500 cuts the first beam changing device 200 out of the beam.
[0045] In this embodiment, the diverging device 300 adopt...

[0066] The difference between the second embodiment and the first embodiment is only that the first beam changing device 200 adopts a beam diverging device 1 202 .
[0067] In this embodiment, the first light beam diverging device 202 adopts a plano-concave lens. In other embodiments, the first beam diverging device 202 may also use a convex-concave lens or a bi-concave lens or a combination of positive and negative lenses.
[0068] refer to Figure 4 ,pass figure 1 The moving device 500 in will cut the beam diverging device one 202 into the beam.
[0069] In this embodiment, the beam diverging device 1 202 receives the beam 101 and diverges to form a diverging beam 222; the diverging device 300 receives the diverging beam 222 and then diverges to form a diverging beam 322; A converging device 400 receives the diverging beam 322 and converges it to form a converging beam 422 .
[0070] continue to refer Figure 4 , after the beam diverging device 1 202 cuts into the beam...

[0075] The optical system includes: providing a light source 100 , a second beam changing device 700 , a second converging device 800 , and a third converging device 900 .
[0076] In this embodiment, the second beam changing device 700 is a beam focusing device 2 701 .
[0077] In this example, refer to Figure 5 , providing a light source 100 , a second beam focusing device 701 , a second converging device 800 , and a third converging device 900 .
[0078] In this embodiment, the beam focusing device 2 701 adopts a biconvex lens. In other embodiments, the light beam focusing device 2 701 may also use a plano-convex lens or a concave-convex lens or a combination of positive and negative lenses.
[0079] In this embodiment, the second converging device 800 is a biconvex lens. In other embodiments, the second converging device 800 may also be a plano-convex lens or a concave-convex lens or a combination of positive and negative lenses.
[0080] In this embodiment, the third...
