Patent ID: 8130444

Claim:
A telescope imaging system, comprising: a first lens group for receiving a spot light and generating a first refracted beam; a second lens group for receiving the first refracted beam and generating a second refracted beam; a third lens group having a convex lens disposed at a side of the third lens group distant from the spot light for receiving the second refracted beam and generating a parallel beam by an effective focus formed by the first lens group, the second lens group and the third lens group; a first reflective mirror having an opening, receiving the parallel beam and generating a reflected beam; and a second reflective mirror adjacent to the third lens group, reflecting the reflected beam, and allowing the reflected beam to pass through the opening and be focused as an image, wherein a first distance between the first lens group and the second lens group is adjustable for forming the effective focus, and a second distance between the second lens group and the third lens group is adjustable for forming the effective focus.
