Zusammenfassung:The present invention proposes a lens system for an endo-microscope probe. The lens system for an endo-microscope probe according to an embodiment of the present invention, which is a lens system for an endo-microscope probe including a plurality of lenses arranged from an object side to an image side, comprises: a first lens (L1) having a flat object side surface and a convex image side surface; a second lens (L2) having an object side (O) with a radius of curvature in a convex shape and an image side (I) with a radius of curvature in a concave shape; a third lens (L3) having both sides with a radius of curvature in a convex shape; a fourth lens (L4) having an object side (O) with a radius of curvature in a convex shape and an image side (I) with a radius of curvature in a concave shape; and a fifth lens (L5) having an object side with a radius of curvature in a concave shape and an image side with a radius of curvature in a convex shape, wherein the first lens (L1) is a glass lens, and the remaining second lens (L2) to the fifth lens (L5) are made of plastic lenses capable of injection molding. Therefore, provided is a lens system for an endo-microscope probe, wherein mass production is facilitated. 본 발명은 내시현미경 프로브용 렌즈계를 제안한다. 본 발명의 일 실시예에 따른 내시현미경 프로브용 렌즈계는, 물체측으로부터 상측으로 배열된 복수의 렌즈를 포함하는 내시현미경 프로브용 렌즈계에 있어서, 평평한 물체측면과 볼록한 상측면을 가지는 제1 렌즈(L1); 물체측(O)은 볼록 형태의 곡률반경을 가지고 상측(I)은 오목 형태의 곡률반경을 가지는 제2 렌즈(L2); 양측이 볼록 형태의 곡률반경을 가지는 제3 렌즈(L3); 물체측(O)은 볼록 형태의 곡률반경을 가지고 상측(I)은 오목 형태의 곡률반경을 가지는 제4 렌즈(L4); 및 물체측은 오목 형태의 곡률반경을 가지고 상측은 볼록 형태의 곡률반경을 가지는 제5 렌즈(L5)를 포함한다. 그리고 상기 제1 렌즈(L1)는 글래스(glass) 렌즈이고, 나머지 상기 제2 렌즈(L2) 내지 제5 렌즈(L5)는 금형 사출 가능한 플라스틱 렌즈로 제조된다.
