Description
Technical field
The utility model relates to spectral detection instrument field, specifically, relates to a kind of switching device of optical fiber.
Background technology
Spectroscopic analysis methods, as a kind of important analysis means, all plays effect greatly in scientific research, production, Quality Control etc.No matter be penetrate absorption spectrum, or fluorescence spectrum, Raman spectrum, obtaining Single wavelength radiation is indispensable means.Because modern monochromator can have very wide spectral region (UV-IR), high spectral resolution (0.001nm), auto-wave long scan, complete conputer controlled function, very easily coordinate for high-performance Auto-Test System with other peripheral equipment, use the many grating spectrographs of computer automatic scan to become the first-selection of spectral investigation.
In spectroscopy applications, obtaining Single wavelength radiation is indispensable means.Except with except monochromatic source (as spectrum lamp, laser instrument, light emitting diode), coloured glass and interferometric filter, scanning is mostly used to select the monochromator of wavelength.Especially the current grating monochromator of application scanning more, selects narrow spectrum (monochromatic or Single wavelength) radiation in the wide wave-length coverage of continuous print (white light).Namely tradition switching device shifter is, by the screw mandrel of stepper motor and screw relative motion, motor axially-movable is become linear movement, because switching device shifter requires that moving displacement is larger, screw mandrel is necessarily required to want long enough, screw mandrel can produce distortion, make bumpy motion, and can produce sample measurement inaccuracy, and this device volume often affects comparatively greatly the appearance and size of equipment.
