摘要： The invention relates to a double telecentric optical system (100) and its use in a sensor device (1000), wherein said optical system (100) comprises a single focusing element, for example a lens (101). A mirror element (102) is arranged at the focal point (F) of this focusing element (101) to reflect incoming light rays back to the focusing element (101). Incoming and reflected light rays preferably pass through different parts (101a, 101b) of the focusing element (101), allowing a spatially separated arrangement of an object (3) and its image (I).

摘要： An imaging lens SL mounted in a single lens reflex digital camera 1 is composed of, in order from an object side, a first lens group G1 having negative refractive power, a second lens group G2 having positive refractive power, and a third lens group G3 having negative refractive power. Upon focusing on a near-distance object from an infinitely distant object, a configuration is that at least any one of the first lens group G1 and the second lens group G2 is moved to the object side to vary a distance between the first lens group G1 and the second lens group G2. Accordingly, a downsized imaging lens having a small moving amount upon shooting a close range object, in which various aberrations are well corrected is provided.
