Description
Technical field
The utility model is related to image/the wide-angle lens of camera technique field, especially anti-dazzle.
Background technology
The feature of wide-angle lens maximum is exactly that can shoot wide range, is had distance perspective exaggerationization, focusing range
It is wide to wait shootings feature.Object at the moment can be put to obtain bigger using when wide-angle, the object of distant place is contracted to obtain smaller, the image of surrounding
It is also its a big feature to be easy distortion.Wide-angle can also be such that any point in image all adjusts to optimal focal length so that
Picture is more clear, and can also be referred to as fully automated focusing.The lens focus of wide-angle digital camera is very short, and visual angle is wider, and
The depth of field is but very deep, is relatively suitble to shooting compared with the photo of large scene, such as building, landscape subject matter.
Wide-angle lens is made of more pieces of eyeglasses, when light enters camera lens, due in wide-angle lens sensitive chip and
Filter glass (including glass on the glass and PLCC on sensitive chip) reflective secondary reflection that can cause light, thus will
It is bad to generate the imaging such as dazzle and ghost.
The utility model is made by adding the method for oblique angle (angle at oblique angle is determined according to actual light path) in lens barrel bottom
The two of sensitive chip and filter glass (including glass on the glass and PLCC on sensitive chip) reflective generation of wide-angle lens
The light of secondary reflection is directly entered on the oblique angle that lens barrel bottom adds, prevent wide-angle lens sensitive chip and filter glass (including
The glass on glass and PLCC on sensitive chip) reflective generation secondary reflection, it is bad to generate the imaging such as dazzle and ghost.
Utility model content
The purpose of this utility model is to provide the wide-angle lens of anti-dazzle, adds oblique angle in lens barrel bottom, makes wide-angle lens
The light of sensitive chip and the secondary reflection of the reflective generation of glass of color filter is directly entered on the oblique angle that lens barrel bottom adds, and is prevented wide
It is bad to generate the imaging such as dazzle and ghost for the secondary reflection of the reflective generation of sensitive chip and glass of color filter of angle mirror head.It is based on
The purpose, the technical solution adopted in the utility model are as follows：
The wide-angle lens of anti-dazzle, including lens barrel, the lens set being installed in lens barrel, optical filter and sensitive chip, it is described
Lens barrel includes outer lens barrel, the first inner lens cone, the second inner lens cone, and eyeglass, the trim ring are fixed with by trim ring on the outer lens barrel
One side close to eyeglass is taper surface；Eyeglass is fixed with by trim ring in first inner lens cone and the second inner lens cone；It is described
The outer port part of outer lens barrel is equipped with upper cover, and the bottom end inner wall of first inner lens cone and the second inner lens cone is equipped with oblique angle, described
The angle of oblique angle and lens barrel center line is acute angle, and the opening direction at the oblique angle is towards the side of optical filter.Trim ring is used for fixing
Eyeglass.To prevent trim ring from blocking the light of intake eyeglass, trim ring makes taper surface on one side close to lens.In the bottom end of lens barrel
Wall is equipped with oblique angle, and incident ray enters optical filter and sensitive chip by oblique angle, reduces reflection, and reflected light is avoided to reach photosensitive core
Piece.
Further, the lens set includes multiple eyeglasses.Due to optical reasons, the imaging of single eyeglass is inevitable
There are some row Aberration Problems of aberration, spherical aberration, coma, astigmatism etc., and especially in marginal portion, imaging is very poor.Multiple eyeglasses
Combination can aberration correction to a certain extent.Secondly, if lens zoom needs multiple eyeglasses to change spacing to realize.And
Become defocused, aberration can change, thus zoom lens generally needs more eyeglasses that could complete zoom and the picture of different focal length
Difference correction.Again, the focusing of many camera lenses is also to change to realize by lens position.
Further, the eyeglass is glass lens and/or glass lens.Sheet glass optical property is superior, and translucency is good,
It is not easy scratching.Glass lens are light, non-breakable, processing and forming is convenient.User can select as needed.
Further, it is detachably connected between the upper cover 5 and outer lens barrel 11.5 waterproof of upper cover, it is dust-proof, it can effectively protect
Goggle head is injury-free, and lens cap is by screw thread or snaps connection on outer lens barrel.
Further, the optical filter is glass filter.The translucency of glass is good, and light is had excellent performance.
Further, the bottom of first inner lens cone, 12 and second inner lens cone 13 is equipped with optical filter mounting groove.It filters
Piece is mounted in entire lens barrel bottom, and optical filter mounting groove fixes optical filter.
Further, first inner lens cone and the second inner lens cone are fixed on by trim ring in outer lens barrel.Inner lens cone group
In outer lens barrel, the first inner lens cone and the second inner lens cone relative position can change, and trim ring, which is fixed, to be dismantled, is easy to adjust.
The advantageous effect that the utility model obtains is：The utility model in lens barrel bottom by adding the oblique angle (angle at oblique angle
Determined according to actual light path) method, make the sensitive chip and filter glass (including the glass on sensitive chip of wide-angle lens
With the glass on PLCC) light of the secondary reflection of reflective generation is emitted directly toward oblique angle (the angle root at oblique angle that lens barrel bottom adds
Determine according to actual light path) on, prevent wide-angle lens sensitive chip and filter glass (including the glass on sensitive chip and
Glass on PLCC) light of the secondary reflection surface reflection that is emitted directly toward each piece of eyeglass of reflective generation can be in camera lens and camera
Multiple reflection inside causes the imaging such as dazzle and ghost bad.
