Be the surface of bullet, the plane of incidence and exit facet to be parallel to each other and perpendicular to incident light direction, the bullet
Plating is provided with highly reflecting films on the conical surface.
Further, the conical surface of the bullet is circular conical surface or pyramidal surface.
Preferably, the pyramidal surface is triangular prism method, rectangular pyramid face, pentagonal pyramid face or N pyramidal surfaces, wherein N ＞ 5.
Further, described bullet is provided with the pyramidal structure of bellmouth orifice, the loudspeaker for solid cone shaped structure or center
The both ends in hole extend respectively to the plane of incidence and exit facet.
Further, plating is provided with anti-reflection film on the described plane of incidence and exit facet.
Preferably, when described bullet center offers bellmouth orifice, the material of the bullet is glass, crystal, gold
Category or high polymer material.
Preferably, when described bullet is solid cone shaped structure, the material of the bullet for can thang-kng glass, crystalline substance
Body or high polymer material.
Wherein, the plane of incidence size on bullet can be processed according to the requirement of actual optical system, and bullet
When center offers bellmouth orifice, the pyramidal structure of the bullet for the pyramidal structure with certain wall thickness or is thin-wall conical knot
Structure.
Using above-mentioned technical scheme, the utility model compared to existing technologies, its have the advantage that for：Profit
With the principle of reflection, the incident light being blocked is carried out by reflection by the conical surface of bullet and causes a deviation from primary optical axis, makes diaphragm not
Incident light energy can be absorbed, avoids damaging caused by diaphragm temperature is too high, so as to improve the use reliability of diaphragm and use
Life-span.
