摘要： A freeform surface imaging spectrometer system including a primary mirror, a secondary mirror, a tertiary mirror, and a detector is provided. The secondary mirror is a grating having a freeform surface shape, and the grating having the freeform surface shape is obtained by intersecting a set of equally spaced parallel planes with a freeform surface. A plurality of feature rays exiting from a light source is successively reflected by the primary mirror, the secondary mirror and the tertiary mirror to form an image on an image sensor. A reflective surface of each of the primary mirror, the tertiary mirror surface and the tertiary mirror is an xy polynomial freeform surface.

摘要： A monolithic optical element and system is used for collimating or focusing laser light from or to optical fibers. The optical fiber terminates in a tip that directly abuts against the first surface of the optical element. The optical element may provide a collimation or focusing function depending upon whether the abutting fiber delivers light for collimation or receives focused light from a collimated beam. The optical element may be a standard or modified barrel or drum lens, with the first and second surfaces being convex curved surfaces having the same or different radii of curvature. The end of the optical element to which the fiber abuts may have a diameter to match the inner diameter of a ferrule for positioning the fiber. A pair of the elements may be used for collimation and focusing in a Raman probehead or other optical detection system.

摘要： A spectrometer (100) and an optical input portion (32) thereof are disclosed. The optical input portion (32) comprises an assembly structure (322), and the assembly structure (322) is formed at a hole wall (321) of a through hole (3211) of the optical input portion (32). A light (L1) is incident into a dispersing element (2) of the spectrometer (100) along an optical path (13) after passing through the through hole (3211), and is dispersed by the dispersing element (2). The assembly structure (322) is used to be detachably assembled with an optical element (200). When the optical element (200) is assembled with the assembly structure (322), an optical axis of the optical element (200) is linked to the optical path (13). As a result, the light (L1) passing through the optical element (200) is incident to the dispersing element (2) along the optical axis and the optical path (13).

摘要： In a measuring probe (40) according to the present invention, measuring light is split into a two or more through a split optical system (12), and, when each split light is received by a light-receiving sensor (13B, 13B, 15B) through an interference filter (13A, 14A, 15A) serving as a color filter, the split light is introduced into the interference filter (13A, 14A, 15A) through a collecting lens group (123C, 14C, 15C) formed as a substantially bilateral telecentric system. The interference filter (13A, 14A, 15A) is formed to obtain a transmittance characteristic corresponding to a measurement parameter, depending on a condition of an intensity distribution with respect to incidents angles of light incident on the interference filter (13A, 14A, 15A). Thus, the measuring probe (40) according to the present invention can reduce an influence of a deviation in the transmittance characteristic due to incident angles, even using the interference filter (13A, 14A, 15A).
