Description
Technical field
The utility model is related to a kind of prism, more particularly to a kind of five jiaos of Amici prisms.
Background technology
Pentagonal prism refers to that two reflecting surface angles are 45 °, and incident light accurately realizes 90 ° of prisms of reflection, and it is light beam
Determine one of angle steering device.Pentagonal prism be different from right-angle prism, imaging both without spin or without mirror-reflection, using this
Characteristic can carry out big plane flatness measurement, i.e., pentagonal prism around trunnion axis rotate when emergent ray in vertical plane
A plane is scanned out, otherwise is rotated around vertical axis, then can determine the flatness in horizontal plane, but, current pentagonal prism point
Light effect is poor, and light loss rate is too high, and precision is too low, and stability is poor, and the wavelength band for adapting to light is small.Therefore, it is proposed that one
Plant five jiaos of Amici prisms.
Utility model content
Main purpose of the present utility model is to provide a kind of five jiaos of Amici prisms, and overall structure is simple, novel in design, point

Rate amendment, with good promotional value, in can effectively solving the problems, such as background technology.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of five jiaos of Amici prisms, including mirror body, Part I, exit facet, the plane of incidence and Part II, in the mirror body
It is divided into Part I, exit facet, the plane of incidence and Part II, in 135 degree of angles between the Part I and exit facet, and two
It is provided with photomask between person, the photomask side is provided with depolarization dielectric film and to be arranged on depolarization dielectric film another
The beam splitting coating of side, is provided with the second diffusion barrier and is arranged on the second diffusion barrier between the photomask and depolarization dielectric film
The bright enhancement film at top, the light guiding film that the bright enhancement film top is provided with the first diffusion barrier and is arranged at the top of the first diffusion barrier.
Further, the light guiding film top is provided with reflectance coating.
Further, light beam reaches Part I from the plane of incidence, then reflexes to Part II, is most projected through exit facet afterwards.
Further, the plane of incidence and Part II angle are 135 degree.
Compared with prior art, the utility model has the advantages that：Due to being between Part I and exit facet
135 degree of angles, the plane of incidence and Part II angle are 135 degree, and beam splitting coating are added between Part I and exit facet, is hidden
Light film, depolarization dielectric film, reflectance coating, the first diffusion barrier, the second diffusion barrier, light guiding film and bright enhancement film, spectrophotometric result are good, light
Loss late is substantially reduced, and precision is higher, and stability is high, and the wavelength band for adapting to light is wider, it is not necessary to emittance correction.
