Description
Technical field
The utility model belongs to optical experiment instrument field, relates to a kind of spectrometer parts, is specially a kind of parallel light tube of automatic light source.
Background technology
Parallel light tube is a critical piece of spectrometer, and its general external light source produces the directional light of experiment.Spectrometer adjustment, with the student experimenting used, has in a usual laboratory that multiple light source is lighted simultaneously, multiple stage spectrometer is tested simultaneously.Because indoor parasitic light is more, comparatively strong, be easy to each other in experimentation produce light disturbance, affect the observation of experimental phenomena, and bring very big inconvenience to experiment measuring.
Summary of the invention
The purpose of this utility model, is the parallel light tube improving spectrometer, develops a kind of parallel light tube of automatic light source, to overcome the light disturbance in spectrometer experiment, improves the experiment effect of spectrometer.
In order to solve the problems of the technologies described above, the utility model by the following technical solutions:
A parallel light tube for automatic light source, comprises hollow cylinder pipe shaft, is fixed on the lens of pipe shaft one end, also comprise the seam light supply apparatus being plugged on the pipe shaft other end, and seam light supply apparatus comprises slit plate, the adapter of hollow garden cylindricality, light source cylinder, light source; The adapter of slit plate side fixed connection, slit plate opposite side rotation-coupled light source cylinder, taking-over activity to be inserted in pipe shaft and by being located at adapter lock-screw on pipe shaft and pipe shaft is fixed; Slit plate is provided with broad-adjustable slit; Light source is fixed on light source cylinder inwall just to the position of slit.
Described lens are convex lens, and its focal length is not less than pipe shaft length.
Described light source is LED, or is sodium vapor lamp, or is mercury lamp.
The beneficial effects of the utility model are: due to parallel light tube automatic light source, the illuminance of slit and the sharpness of imaging can be guaranteed, be advantageously used in spectrometer adjustment and measure the experiments such as prism drift angle, light disturbance can not be produced to other spectrometers, avoid the light in spectrometer experiment to judge by accident, be conducive to accurate observation and the measurement of experimental phenomena.
