Claim 6:
7. The discrete light detection device as claimed in claim 1, wherein the collimation unit further comprises:
a first convex lens, having a first focal length; and
a second convex lens, having a second focal length; wherein the second focal length is longer than the first focal length;
wherein a position of a first focal point of the first convex lens overlaps with a position of a second focal point of the second convex lens;
wherein after the Raman scattered beam passes through the optical filter, the Raman scattered beam shoots through the first convex lens of the collimation unit and shoots through the second convex lens of the collimation unit;
wherein the Raman scattered beam is collimated into the collimated beam by the second convex lens.
