Description
Technical field
The invention belongs to field of optical device technology, and in particular to a kind of polarizing film lens cap.
Background technology
Polarizing film refers to the optical element that natural light can be made to become polarised light, the work(for having masking to incident light and penetrating
Can, there are black and white and colored two classes, can be divided into transmission, transflector again by application and counter transmit three classes.Polarizing film has incident light
Masking and the function of penetrating, can make longitudinal light or a kind of transmission of lateral light, a kind of masking.It is by polarizing coating, inner protection film, pressure
Composite material made of quick glue-line and the lamination of outer protective film.
In recent years, people carry out the shooting of personage and landscape when amusement and travel commonly using camera, and camera is in people
Life in using more and more common, and the service life of camera and shooting effect are in addition to the quality of hardware factor by itself
Outside, the maintenance and maintenance of camera also function to certain effect, therefore for the maintenance of phase machine part also increasingly by people
Attention.The minute surface of camera lens and internal light sensitive device are easier to be damaged in phase machine part, and camera is in unused shape
When state, camera lens generally use lens cap to protect camera lens, prevent external dust, dust storm or sleet etc. from damaging camera lens, have simultaneously
Evil light can not damage the light sensitive device of camera internal, but there are problems that lens cap is easily lost；In use state, phase
Machine generally uses hood to reduce influence of the harmful light for imaging, but camera lens is constantly exposed to sunlight in the process
Under, exposed time length can influence the service life of camera internal sensor devices, while camera lens be also subject to dust, dust storm,
The invasion of sleet be easy to cause the damage of lens wearer；The use process of camera, which is roughly divided into, finds a view and shoots two stages, such as
What can reduce camera using when camera lens exposure duration extend camera service life be very important project.
Application No. is a kind of collapsible lens cap with hood function of the patent disclosure of CN201720682859.4,
Including camera lens connection ring, pedestal, upper cover, lower cover, left and right side cap, fold line, magnetic-suction buckle, iron plate.Although this patent is convenient for people
Equipment camera lens can either be protected well when using camera, and it will not be made to be easy to lose or cause other inconvenient,
The opening and closing operation of the collapsible lens cap is all very easy to be easy, no matter in opening and closing shape after being connect with camera lens
It is all not necessarily to take off from camera lens under state, to protect camera lens from accident collision, additionally it is possible to cover dust, blocking sleet well
It splashes on camera lens, and has the function of hood.But this patent still can not cover ash when people image and find a view
Dirt, blocking sleet splashes on camera lens and shading.
Application No. is a kind of difunctional lens caps of full shot of the patent disclosure of CN201120542607.4, including this
Lens cap is hollow garden platform shape, has connection screw thread on the inside of lid mouth, which can be with the Hemispheric panoramic imaging system of full shot
External screw thread matching connection；Lens cap both sides inclined-plane is equipped with the veiling glare screw thread that disappears.Although this patent can realize lens cap effectively
Prevent the function of piping and druming and the dust entrance of dust storm；It can realize that hood is effectively prevented non-imaged light, scattering light and interference again
Light enters the function of camera lens, but this patent still can not prevent dust storm and dust when people's camera shooting is found a view, and also can not
Reduce damage of the light for camera internal sensor devices.
Therefore, development is a kind of has the function of blocking dust, dust storm, sleet, harmful light, extends the mirror of camera service life
Skull is very important.
Invention content
In view of the problems of the existing technology, the purpose of the present invention is to provide a kind of polarizing film lens caps.The present invention one
Kind polarizing film lens cap has blocks dust, dust storm, sleet when finding a view；Lens cap exposure duration is reduced, light pair is reduced
In the damage of camera internal sensor devices the advantages that.
In order to solve the above technical problems, the technical solution adopted by the present invention is.
A kind of polarizing film lens cap, including first layer connector, second layer connector and third layer connector are removable successively
