Description
Technical field
The utility model is related to astronomical popularization field, more particularly to a kind of spectrograph can be used for shooting solar spectrum.
Background technology
Currently, spectrograph in the market is complicated, and it is at high price, it is higher to the processing request of component, and without special
For the movable spectrograph of astronomical popularization, it is particularly useful for shooting the spectrograph of solar spectrum.
Invention content
The utility model provides a kind of spectrograph for the above-mentioned market demand.
The technical solution of the utility model is such：A kind of spectrograph, including the upper Barlow lens zoom of interconnection are prolonged
Long cylinder and lower Barlow lens zoom extending, the upper Barlow lens zoom extending and lower Barlow lens zoom extending are hollow cavity
Shape；It is equipped in the upper end of the upper Barlow lens zoom extending and subtracts burnt mirror, the upper end for subtracting burnt mirror is set with helical focussing mount, spiral shell
The upper end of rotation focusing mount is provided with slit；Direct-view rib is installed in the lower end hollow cavity of the lower Barlow lens zoom extending
Mirror；The lower end of the lower Barlow lens zoom extending is connected with eyepiece, and the lower end of eyepiece is installed with camera；Lower Barlow lens zoom
The hypomere outer ring of extending and the outer ring of eyepiece are set with photography sleeve.
Preferably, the outside of the slit set is provided with make-up lock screw.
Preferably, being provided with lower tight lock screw on the outside of the photography sleeve.
The utility model has the beneficial effects that：A kind of spectrograph can be used for shooting sunlight, simple in structure, low cost
It is honest and clean, and all components all can be in buying in the market, materials are easy, convenient for promoting.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of spectrograph.
Specific implementation mode
Specific embodiment of the present utility model is described in detail below in conjunction with Fig. 1.
As shown in Figure 1, the assembling mode of the structure and its building block of a kind of spectrograph, each component is：By direct vision prism 6
Subtract burnt mirror 3 with 0.5X to be separately mounted on 1.25 inches of lower Barlow lens zoom extendings 2 prolong with 1.25 inches of upper Barlow lens zooms
On long cylinder 1；Upper Barlow lens zoom extending 1 is connected with lower Barlow lens zoom extending 2, then descends Barlow lens zoom extending
2 are connected with PL25 eyepieces 7, screw on ASI174MC cameras 8；Lower Barlow lens zoom extending 2 is connected with photography sleeve 9, will even
The eyepiece 7 connected and lower Barlow lens zoom extending 2 penetrate among photography sleeve 9, and make lower Barlow lens zoom extending 2 with
Sleeve 9 of photographing connects；The upper end of upper Barlow lens zoom extending 1 is injected in helical focussing mount 4, then slit 5 is fixed on spiral shell
In the M42 screw threads for revolving focusing mount 4；Screw on ASI174MC cameras 8.
It as deduction, is connected on telescope if necessary, then can add T, adjustable slit 5 is connected on T cylinders.
As deduction, other different size models with the same function may be used in the specifications and models of above-mentioned building block
Part replacement.
The debugging process of the spectrograph is：Spectrograph is fixed on three feet using the screw thread of 8 behind of ASI174MC cameras
On frame, slit 5 is directed at energy-saving lamp, it is ensured that camera 8 is successfully connected computer；After opening energy-saving lamp, it can be shown on screen energy saving
The spectrum of lamp, adjustment spectrograph is mainly using the mercury two-wire of energy-saving lamp as target；If image is not rectangle, unscrew make-up lock spiral shell
Silk 41 rotates helical focussing mount 4, and image is made to become rectangular, then tightens make-up lock screw 41；If image tilts, unscrew lower tight
Screw 91 is locked, helical focussing mount 4 is rotated, makes image rotation to suitable position, then tighten lower tight lock screw 91；If image mould
Paste unscrews lower tight lock screw 91, pulls helical focussing mount 4, changes between camera CMOS chip and 7 lens group of PL25mm eyepieces
Distance.If it is fine tuning, then the focusing ring of rotatable helical focussing mount 4, change slit 5 and 0.5X subtract burnt mirror 3 away from
From；When image direction is horizontal, and mercury two-wire is clearly seen, spectrograph adjustment is completed, and spectrograph can be used for shooting at this time
Target light source spectrum.
The utility model is simple in structure, cheap, is very suitable for astronomical popularization activity and is used.
It these are only the preferred embodiment of the utility model, the substitute equivalents done according to above-described embodiment or deduction,
The covering scope of the utility model should be belonged to.
