Description
Technical field
The present invention relates to a kind of physics facility, be specially a kind of parallel light tube slit light modulator for spectrometer.
Background technology
Spectrometer is a kind of conventional optical experiment instrument.Parallel light tube on spectrometer is for generation of directional light.One end of parallel light tube is object lens, and the other end is broad-adjustable slit arrangement.This slit arrangement, when reality uses, because student frequently regulates, adds undue force, the control hand wheel of slit often can be caused malfunctioning and cannot regulate slit width again, causing slit wide, narrow even completely closed, thus cannot continue experiment.In addition, in adjustment process, the concrete width of slit cannot be known.
Summary of the invention
The object of the invention is to invent a kind of parallel light tube slit light modulator for spectrometer experiment that is not fragile, change slit width easily.
In order to solve the problems of the technologies described above, the present invention by the following technical solutions:
A kind of parallel light tube slit light modulator, comprises pedestal, slit cover, optical filtering upper shield, and enters light pipe for what be flexibly connected with parallel light tube;
Described pedestal is cylindrical, pedestal has the diameter of a vertical base end face to equal into light pipe external diameter through hole near circumference place, described in enter light pipe and penetrate through hole and pedestal fixed connection;
Described slit cover is circular lid, its diameter is slightly larger than pedestal external diameter, slit cover is set on pedestal, slit cover center and base central rotation-coupled, slit cover freely can rotate around base central, along angular separation such as radial directions, the lid end face of slit cover is distributed with that one group of length is equal, width light penetrating slit not etc.;
Described optical filtering upper shield is circular, its diameter is slightly larger than slit cover external diameter, optical filtering upper shield is set on slit cover, the upper shield end face of optical filtering upper shield circumferentially have for generation of the polaroid of polarized light, for making incident light irradiate uniform light guide sheet, for filtering the optical filter of incident light, polaroid, light guide sheet, optical filter are circle, diameter is identical, and polaroid, light guide sheet, filter center to equal on pedestal through hole center to the distance at base end face center to the distance at upper shield end face center.
Described light penetrating slit totally 8, its width is respectively 0.1mm, 0.2mm, 0.3mm, 0.5mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm.
The invention has the beneficial effects as follows: during experiment, by rotating slit cover, the light penetrating slit of different in width can be selected, when needing in testing to use polaroid, light guide sheet, optical filter, putting optical filtering upper shield and rotating selection.The optical filtering of the light penetrating slit of different in width and difference in functionality, leaded light device are combined by the present invention respectively, facilitate experimental implementation, and not fragile, are conducive to experiment control light, improve conventional efficient and effect.
