摘要： An image quality is improved although a medical stereomicroscope optical system and a medical observation apparatus are small and light.
An objective optical system and a plurality of imaging optical systems are arranged in an order from an object side to an image side, and the imaging optical system has at least a single aspheric surface. Accordingly, a spherical aberration and a field curvature are improved, and the image quality is improved although the medical stereomicroscope optical system and a medical observation apparatus are small and light.

摘要： An optical system of an LED variable-focal-length imaging lamp comprises an LED light source module (1), a light-gathering assembly (2), a cutting assembly (3) and a zoom lens group that are successively mounted along a light path. Geometric centers of these components are collinear with a primary optic axis A, and a focus F1 of the light-gathering assembly (2) coincides with a focus F2 of the zoom lens group. The zoom lens group comprises a first zoom lens (4), a diaphragm (5) and a second zoom lens (6). The first zoom lens (4) and the second zoom lens (6) can move back and forth along the primary optic axis A to achieve a variable focal length, and the diaphragm (5) is provided between the first zoom lens (4) and the second zoom lens (6) and has an adjustable clear aperture. Such an optical system may be widely applied in an LED variable-focal-length imaging lamp, to replace an existing LED fixed focal-length imaging lamp with different angles and high-consumption halogen-bubble light source imaging lamp. By designing a diaphragm (5) in a zoom lens group, off-axis aberration can be effectively alleviated, off-axis stray light can be reduced to pass through, and a clearer image can be formed.
摘要翻译：一种LED可变焦距成像灯的光学系统，包括LED光源模块（1），聚光组件（2），切割组件（3）和变焦透镜组，路径。这些组件的几何中心与主光轴A共线，并且聚光组件（2）的焦点F1与变焦镜头组的焦点F2一致。变焦镜头组包括第一变焦镜头（4），光圈（5）和第二变焦镜头（6）。第一变焦镜头（4）和第二变焦镜头（6）可以沿着主光轴A来回移动以实现可变焦距，并且光圈（5）设置在第一变焦镜头（4）和第二变焦镜头（6）并具有可调的通光孔径。这种光学系统可以广泛应用于LED可变焦距成像灯中，以取代现有的具有不同角度的LED固定焦距成像灯和高消耗卤素气泡光源成像灯。通过在变焦透镜组中设计光阑（5），可以有效地减轻离轴像差，减少离轴杂散光穿过，并且可以形成更清晰的图像。

摘要： A zoom lens having a reduced thickness in the depth direction and a reduced size. A zoom lens that has lens groups (GR1-GR5) and where its magnification is varied by varying the distances between the groups is provided. The zoom lens includes a prism (G2) for refracting the optical axis passing through the lens groups (GR1-GR5). A negative lens group and a positive lens group are arranged, in that order from the object side and with air gaps in between, in the lens group (GR5), counted from the object side, of the lens groups (GR1-GR5). An imaging device is also provided, and the imaging device has an imaging element for converting an optical image formed by the zoom lens into an electric signal.

摘要： A relay zoom system ZL includes, in order from an object side, a first lens group G1 having a positive refractive power and a second lens group G2 having a positive refractive power. Furthermore, in the relay zoom system ZL, the first lens group G1 and the second lens group G2 are each made up of at least two positive lenses and one negative lens. The first lens group G1 and the second lens group G2 in the relay zoom system ZL are configured so as to move along an optical axis when magnification is varied from a lower magnification edge state to a higher magnification edge state.
