Abstract
The invention discloses a fixed wavelength measuring device for a continuous light source. The fixed wavelength measuring device comprises a light source, a spectroscope, a flow cell, a slit slab, a concave grating, a plane mirror and a photocell array. Light emitted by the light source enters the flow cell through the spectroscope, the light going out from the flow cell irradiates to the concave grating after passing through the slit slab, the concave grating reflects the light to the plane mirror, and the light is reflected by the plane mirror to the photocell array. According to the fixed wavelength measuring device for the continuous light source, a tritium lamp can be used as the measurement light source, optical information is finally reflected into the photocell array after the light source passes through the flow cell, and finally the wavelength of the continuous light source is figured out through a computer processing system. The fixed wavelength measuring device is simple in structure, accurate in measurement result, convenient to operate and suitable for wavelength measurement of most continuous light sources.
Description
Technical field
The present invention relates to optical source wavelength pick-up unit, particularly a kind of continuous light source fixed wave length pick-up unit.
Background technology
Visible ray is the appreciable part of human eye in electromagnetic wave spectrum, and visible spectrum does not have accurate scope; The appreciable electromagnetic wavelength of eyes of common people between 400 to 800 nanometers, but also has some can perceive the electromagnetic wave of wavelength greatly between 380 to 780 nanometers.Optical wavelength measurement is the technical field grown up along with optical fiber communication, it is inseparable with the development level of optical fiber communication. the height of optical wavelength measurement technology is one of key factor determining optical communication state of development, therefore, to the research of optical wavelength measurement technology, there is great practical value and theory significance.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of can the continuous light source fixed wave length pick-up unit of Quick Measurement.
The present invention in order to the technical scheme solving its technical matters and adopt is: a kind of continuous light source fixed wave length pick-up unit, comprise light source, spectroscope, flow cell, narrow slit flat-plate, concave grating, level crossing and photovoltaic cell arrays, the light that described light source sends circulates pond after spectroscope, expose to after narrow slit flat-plate concave grating from flow cell light out, light is reflexed to level crossing by described concave grating, then by flat mirror reflects in photovoltaic cell arrays.
As a further improvement on the present invention, described light source is tritium lamp.
The invention has the beneficial effects as follows: continuous light source fixed wave length pick-up unit of the present invention can utilize tritium lamp as measurement light source, optical information is finally reflexed in photovoltaic cell arrays by light source after flow cell, the wavelength of continuous light source is calculated eventually through computer processing system, apparatus structure of the present invention is simple, measurement result is accurate, easy to operate, be applicable to the wavelength measurement of most continuous light source.
