| 摘要 |
The invention relates to a portable spectromicroscope for in situ carrying out spectrometric and microscopic analysis of an opaque, solid, pulverous or viscous material. According to the invention, the spectromicroscope comprises a probe (S), an electronic unit (E) and a portable computer (C) provided with a specific software, wherein the probe (S) consists of a cylindrical body (2) wherein an optical fibre (3) is divided into twelve fibres (4...4), radially arranged around another optical central fibre (5), from a group of optical focusing lenses (6) provided with a threaded fitting (7) and a blocking nut (8) and also an optical divider (9), and wherein the electronic unit (E) consists of a radiation source (12), a miniature spectrometer (13) with diode-array detector and a miniature video-camera (14). The probe (S) may be provided with a set of extending bodies (16) for the optical fibres (4...4and 5), said bodies (16) being provided at the upper side with an optocoupler (15) and at the lower side either with an optical device (17) having a flooding window (f) and a miniature mirror (18) making possible the spectrophotometering of the solutions directly in containers or chemical and biochemical reactors, at various depths, or with an optical device (19) containing a mirror (20) with a total reflection, the threaded fitting (7) and the group of optical focusing lenses (6), making possible the spectrophotometering and the microscopic examination of the limiting layer between the solution to be analysed and the wall of storage container. |
