Description
Technical field
The utility model relates to a kind of optical imagery part, particularly relates to a kind of anti-dazzling screen.
Background technology
Anti-dazzling screen is used for being the optical element for regulating and controlling light quantity in optical system, when extraneous light enters camera lens, can stop that unwanted light enters via the anti-dazzling screen put between the lenses.Though but in optical system, use anti-dazzling screen to reach the effect controlling light, but when light is radiated at the section of anti-dazzling screen perforation, it is from the light of fault plane reflection and diffusion, also interference is caused to optical system, such as at photographic lens, these parasitic lights create the unnecessary image such as ghost or credit light on lens imaging face.Early stage Lens is larger, anti-dazzling screen section thickness is more than lens length hour, the impact of these parasitic lights is not remarkable, but when lens length reduces, when anti-dazzling screen thickness accounting improves, when being particularly used in thin type cell phone camera lens, the ghost of imaging surface and credit optical phenomenon just remarkable especially, therefore how to process anti-dazzling screen section just very important.
The parasitic light process invention of relevant anti-dazzling screen reflection, in the patent of patent No. TWI235103 on the 1st July in 2005, disclose a kind of method eliminating parasitic light outside effective aperture, namely the method forms uneven surface in the upper and lower surface of anti-dazzling screen on the film benevolence surface of ejection formation.
January in 2010 patent No. TWI402608 on the 1st patent in disclose and use stainless steel material as the method for anti-dazzling screen, have employed stainless steel feature more on-deformable than plastic materials such as polyester (Polyester), by anti-dazzling screen slimming, namely this invention makes reduction processing to reduce the reflected light of anti-dazzling screen section for anti-dazzling screen thickness.
The patent TWI400551 that on November 1st, 2011 is open, the process on inclined-plane is then done for the end face at anti-dazzling screen center bore edge, this invention is pressed into inclined-plane at the material near anti-dazzling screen endoporus place, also be thinned anti-dazzling screen edge end face simultaneously, make the thinning reflected light reduced from the generation of anti-dazzling screen section of end surface thickness.
The patented claim that on February 16th, 2011 is open, application number TW201106037, then direct when optical mirror slip ejection formation, the related eyeglass upper limb in injection, in camera lens optical axis center position structure laciniation, reflex to eliminate parasitic light the ghost or light of shining that eyeglass causes accordingly, but the method is for being attached on eyeglass, construct with ejection forming method, not as aforementioned techniques directly improves from anti-dazzling screen body.
