Description
Technical field
The present invention relates to astronomical observation instrument and apparatus field, especially a kind of ground seals inflatable horizontal solar telescope.
Background technique
Sun imaging observation data are to carry out Solar Physics research and the most basic observational data of solar activity prediction, and obtain
Taking the most important equipment of sun imaging observation data is exactly ground horizontal solar telescope.According to diffraction limit formula, optical system
Bore gets over senior general and brings higher resolution ratio.Therefore, in order to obtain the solar activity information of smaller scale, the ground sun is looked in the distance
The bore of mirror constantly increases.
Before 2000, horizontal solar telescope bore is mostly at 1 meter or less.In order to protect optical element, telescope has mostly used envelope
Closed type structure, meanwhile, in order to further eliminate optical device overheat bring Mirror thermal distortion and local seeing effect, to mirror
Cylinder carries out vacuumize process, forms vacuum type horizontal solar telescope.2000 so far, as horizontal solar telescope bore breaches rice
Grade, has reached 2 meter levels and 4 meter levels in succession.Since the manufacture of heavy caliber Hermetic window glass is difficult and the influence of piezobirefringence effect, ground
Base heavy caliber horizontal solar telescope gradually abandons vacuum type design, starts using open type design --- i.e. all optical devices are sudden and violent
Reveal in the environment, meanwhile, by carrying out thermal control to devices such as hot diaphragm and primary mirrors, to reduce Mirror thermal distortion and part view rather
Spend effect.

With the defect overcome.
High vacuum degree is required in vacuum type horizontal solar telescope lens barrel confined space, therefore to telescope configuration
Air-tightness proposes very high request, is limited to sealed horizontal, and often telescope needs periodically pumping to remain higher in lens barrel
Vacuum degree (general every 1-2 weeks with regard to needing to carry out pumping maintenance), increases the maintenance and operating cost of telescope；Due to telescope
It is inside and outside there are the pressure difference of a nearly atmosphere, biggish pressure is formd to lens barrel structure, is unfavorable for the stabilization of telescope configuration
Property；Although higher vacuum degree has been inherently eliminated local seeing effect in lens barrel, primary mirror is due to by direct spoke
According to without carrying out effective thermal control, there are biggish Mirror thermal distortions, influence system imaging performance；Further, since bigbore
Hermetic window glass is difficult to manufacture, this also looks in the distance fundamentally limiting vacuum type horizontal solar telescope more heavy caliber sun more than meter level
Application in mirror.
All ray machine parts are directly exposed in environment in open type horizontal solar telescope, directly by extraneous misty rain, sand and dust
Influence, will cause optical surface in short term by dust pollution, need periodically to carry out wiping maintenance to mirror surface；It will make for a long time
Optical surface plated film is corroded, and needs to carry out plated film and adjustment again to optical device.These problems all greatly affected
The operation of open type sun prestige glasses.
Based on background above, the invention proposes a kind of grounds to seal inflatable horizontal solar telescope.The present invention is using sealing
The design of formula lens barrel, this advantage of optical device can preferably be protected by taking full advantage of vacuum type horizontal solar telescope；By being filled with inertia
Gas balances lens barrel internal and external pressure difference, eliminates pressure difference bring structural instability；Meanwhile to hot diaphragm and primary mirror
Thermal control is carried out, the influence of Mirror thermal distortion and local seeing effect is greatly reduced.Existing vacuum has been gathered in the invention
The advantages of formula and open type horizontal solar telescope, and effectively evaded respective defect, there is very strong innovation and practicality.
