The utility model telescope belongs to Ruland-MAKstutov optical telescopes in the refraction-reflection in telescope, different
In the telescope of other horse card telescopes of in the market, belong to a kind of new modified telescope.The utility model telescope
Coke ratio F/D=6.8, but in the market other telescopes substantially all in F/D=12, F/D=15.
The support that the utility model telescope front end is used adds the structure of eyeglass, unlike other telescopes are used greatly
Lens, so, this can make this telescope it is lightweight a lot.
The utility model telescope reaches 300mm using 2 reflective mirrors and 7 groups of lens compositions, maximum effective aperture, than
The other products bore of in the market is bigger, and precision is higher, and normal others telescope is that 2 reflective mirrors plus 1 lens are constituted, slightly
Miscellaneous structure is made up of 2 reflective mirrors plus 3 lens.The utility model telescope, which is employed, to be reached 7 lens to increase
The optical imagery quality of telescope.Outstanding simultaneous catadioptric design can match in excellence or beauty any professional system.And looked in the distance for astronomy
Catadioptric the utility model telescope of mirror set up a higher standard.
Main reflective mirror is spherical eyeglass, in order to make up the aberration of sphere, it would be desirable to which lens one, lens two carry out corrective lens (eye protection)
Head, photographer needs to be imaged flat field in photography, so we need addition lens three and lens four.
Lens five, six, seven mainly reduce focal length, and focal length is shortened to 2040 from 3000, and it is f/6.8 to reach coke ratio, this
It can be that photographer accomplishes that full frame is photographed that the benefit of sample, which is,（Imaging region is 42 millimeters）, make imaging brighter, more high definition, shorten
The time for exposure of camera, improve rate in blocks.
This patent is a structure for having speculum and telescope of turning back concurrently, but it is different from Newtonian reflective mirror,
The refract-reflect telescope of Schmidt is different from, does not have correcting plate, the only mechanism such as arm-tie and regulating block connection one at its front ferrule
Individual reflective mirror and two lens, are so different from the other optical systems of in the market, and benefit is can to reduce very big weight.This
The advantage for the design structure planted is the reduction of the aberration that correcting plate is likely to result in, aberration, the school of the monoblock of Schmidt telescope
Positive plate also makes whole lens barrel be in closed state so that the constant temperature time of lens barrel is longer.And this structure uses metal just
Arm-tie holds adjustment seat, and whole space is open so that more preferable experience effect can be obtained when user uses and work is imitated
Rate.Have the disadvantage first three piece eyeglass of the system or heavier, hold and be possible with reference to the telescope arm-tie of traditional Newton formula,
But, in use the optics optical axis of whole system may be made to fall partially because of the vibration of generation, user is inconvenient
Debugging, so our centres of three lens in the pre-connection have added the larger spring of an elastic force, for shock-absorbing.Even screw
Loosen, it is very tight that middle elastic mechanism can also draw lens frame, makes the optical axis of lens barrel be unlikely to run away.Improve the qualified of product
Rate.Regulating block and picture frame close-fitting, can be maintained at the optical axis for ensureing three eyeglasses above with six other lens light axis
On one straight line.Governor motion of the present utility model is also very simple, it is only necessary to three regulation spiral shells of light regulating porch
Nail can just collimate the lens barrel.
