The invention relates to the technical field of optical instruments and particularly relates to a secondary total reflection single capillary X-ray focusing lens, an analyzing apparatus and a preparation method of the secondary total reflection single capillary X-ray focusing lens. The secondary total reflection single capillary X-ray focusing lens comprises a main body. The main body is coaxially provided with a truncated ellipsoid portion and a truncated conical portion from left to right. The end surface of the truncated ellipsoid portion far away from the truncated conical portion is an inlet end surface, the other end surface of the truncated ellipsoid portion is the beginning end surface of the truncated conical portion, the other end surface of the truncated conical portion is an outlet end surface and a diameter ratio of the inlet end surface, the beginning end surface to the outlet end surface is 80 to 120: 50 to 70: 1. The secondary total reflection single capillary X-ray focusing lens can converge the conventional laboratory X-ray tube, acquire a small focal spot of less than 10 microns, can be combined with a micro X-ray source, can be processed into a portable X-ray micro-zone analysis apparatus and has a potential application prospect in field on-site operation such as unknown mineral identification and biological sample on-site test.

The invention relates to a positioning device (100) for positioning a light-conducting fibre (206) in a calibration port (208) of a medical device (202) having at least one light source (204) for thelight-conducting fibre (206), wherein the positioning device (100) has an elongated body (102) with two end surfaces (110, 112) and at least one side surface (116). A channel (104) for receiving the light-conducting fibre (206) is formed in the body (102), which extends from a first end surface (110) along a longitudinal axis of the body (102). According to the invention, at least in sections in the region of the channel (104), the body (102) consists of an opaque material and/or is coated with an opaque material, and has at least one opening (113, 118) which extends from a side surface (116)and/or the second end surface (112) of the body (102) to the channel (104), such that radiation emitted from the light-conducting fibre (206) can only pass out of the positioning device (100) unhindered through the at least one opening (113, 118).
