Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing and specific embodiment, be used for explaining the utility model in this illustrative examples of the present utility model and explanation, but not as to restriction of the present utility model.
Shown in Fig. 1-12, present embodiments provide a kind of filtering lens unit with CPL polariscope and adjustable dim light mirror, it comprises: the first eyeglass seat 101, second eyeglass seat 102, first circular polarization eyeglass 201, second circular polarization eyeglass 202, the 3rd circular polarization eyeglass 203, first annular seating 301, second annular seating 302.
For convenience, the present embodiment is with when applying the filtering lens unit of the present embodiment, and enter the direction of filter as a reference with light, with light upstream end for front end, light enters from the rear end of filter out from the front end of filter.
First eyeglass seat 101 is positioned at the front end of the second eyeglass seat 102, be fixed in the first eyeglass seat 101 just over the ground before and after first circular polarization eyeglass 201, second circular polarization eyeglass 202,3rd circular polarization eyeglass 203 is fixed in the second eyeglass seat 102, second eyeglass seat 102 can rotate under the adjustment of user in vertical plane, and the first eyeglass seat 101 can rotate with the second eyeglass seat 102 under the setting of user simultaneously in vertical plane.
Wherein, when the second circular polarization eyeglass 202, the 3rd circular polarization eyeglass 203 rotate (namely deflecting) relatively, second circular polarization eyeglass 202, the 3rd circular polarization eyeglass 203 combination realize ND filter function, and namely now the second circular polarization eyeglass 202, the 3rd circular polarization eyeglass 203 form adjustable N D filter function.
First eyeglass seat 101 is arranged in the second annular seating 302, second eyeglass seat 102 is arranged in the first annular seating 301, second annular seating 302 is fixed on the top of the first annular seating 301, can be, but not limited to be fixedly connected with by screw between first annular seating 301, second annular seating 302, make the first eyeglass seat 101, second eyeglass seat 102 between the first annular seating 301 and the second annular seating 302.
So in use, the front of filtering lens unit can be positioned at by CPL filter function, adjustable N D filter function is positioned at filtering lens unit rear, when applying, user makes the second eyeglass seat 102 can rotate in vertical plane under the adjustment of user by regulating, first eyeglass seat 101 is motionless, even if the second eyeglass seat 102 rotates in vertical plane relative to the first eyeglass seat 101, now the second circular polarization eyeglass 202, 3rd circular polarization eyeglass 203 forms adjustable N D filter function, after the transmittance of adjustable N D filter is adjusted to required degree by user, first eyeglass seat 101 is rotated with the second eyeglass seat 102 simultaneously in vertical plane, second circular polarization eyeglass 202, 3rd circular polarization eyeglass 203 does not form adjustable N D filter function, now lens are CPL filter function, user regulates the CPL filter function of this filtering lens unit, until degree of polarization reaches required degree.
As the signal of the present embodiment, in this filtering lens unit, the front of the first circular polarization eyeglass 201, the 3rd circular polarization eyeglass 203 is all forward, the second circular polarization eyeglass 202 is contrary with the first circular polarization eyeglass 201, and positive backward-facing.
Therefore, adopt the filtering lens unit of the present embodiment that three circular polarization eyeglasses can be adopted can to realize CPL filter function and adjustable N D filter function, user only need buy the present embodiment filtering lens unit can realize CPL filter function and adjustable N D filter function, and the switching only needing by regulating the first eyeglass seat 101, second eyeglass seat 102 can realize CPL filter function and adjustable N D filter function, and without the need to carrying out the dismounting of eyeglass, operation is given long simple, convenient, fast.
As the signal of the present embodiment, the present embodiment can realize adjustment to the first eyeglass seat 101 by the following technical programs, and the first eyeglass seat 101 and the second eyeglass seat 102 integrally regulate jointly, specific as follows:
