Abstract
The utility model provides a filter module comprising a first polariscope, a second polariscope, a first stage regulating ring and a second stage regulating ring; and the first stage regulating ring encircles the periphery of the first polariscope, and the second stage regulating ring encircles the periphery of the second polariscope.
Description
Technical field
The utility model relates to a kind of photographic part, relates in particular to a kind of filter module.
Background technology
Digital camera has been current universal filming apparatus, be easy to export to the relevant devices such as computing machine, wherein filter is one of its photographic part commonly used, often be arranged on the front end of camera lens, in order to filter out the light with special properties, filter comprises ultraviolet filter, infrared filter, dim light mirror, polariscope etc.Wherein the dim light mirror also is middle gray density mirror, neutral gray scale mirror or is called for short gray scale mirror, ND mirror, and its Main Function is to reduce light quantity to enter camera; Polariscope also is polariscope, being called for short the PL mirror, is a kind of color filter, and polariscopic outstanding function is to allow selectively the light of certain direction vibration pass through, in colored and black-and-white photography, be commonly used to eliminate or weaken the reflective by force of nonmetallic surface, thus elimination or alleviate hot spot.The most filter of domestic market is single filter, can not realize the combination of two kinds or two or more filter, realizes two or more filter function simultaneously.
The utility model content
The purpose of this utility model is to provide a kind of filter module, can carry out regulating and controlling to entering light quantity, and the capable of regulating polariscope is realized the effect of subduing of polarized light.
To achieve these goals, the utility model provides a kind of filter module, comprises the first polariscope and the second polariscope, first order regulating ring and second level regulating ring; First order regulating ring is around being arranged at around the first polariscope, and second level regulating ring is around being arranged at around the second polariscope.
According to described filter module, first order regulating ring is the dim light regulating ring, realizes the control into light quantity; Second level regulating ring is the polarized light regulating ring, realizes that polarized light subdues.
According to described filter module, described second level regulating ring comprises the structure housing.
According to described filter module, described first order regulating ring adopts rotational structure to be connected with second level regulating ring; Second level regulating ring adopts rotational structure to be connected with the structure housing; Rotary resistance between second level regulating ring and structure housing is greater than the rotary resistance between first order regulating ring and second level regulating ring.
According to described filter module, comprise the locking device be connected with second level regulating ring, this locking device is for locking the second regulating ring.
According to described filter module, comprise the set collar be connected with second level regulating ring, this set collar is provided with the screw thread bayonet socket be connected with camera lens.
The filter module that the utility model provides, by the first polariscope and the second polariscope being set respectively to entering light quantity and polarized light is regulated, because second level regulating ring is larger with the rotary resistance of second level regulating ring than first order regulating ring with the rotary resistance of structure housing, so can only to the first polariscope, be regulated, be realized the control into light quantity; When rotation second level regulating ring, make first order regulating ring can synchronize and rotate with second level regulating ring, make two polariscopes combination rotation realize that polarized light subdues, obtain the better picture of effect, so just realize that single filter module obtains the effect into light quantity is controlled and polarized light is subdued, simple in structure, handled easily.
The accompanying drawing explanation
Fig. 1 is the structural representation of embodiment filter module.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Shown in Fig. 1, a kind of filter module that the present embodiment provides, comprise the first polariscope and the second polariscope (not shown), first order regulating ring 10 and second level regulating ring 20, first order regulating ring 10 is around being arranged at around the first polariscope, and second level regulating ring 20 is around being arranged at around the second polariscope.Wherein, first order regulating ring 10 is the dim light regulating ring, realizes the control into light quantity; Second level regulating ring 20 is the polarized light regulating ring, realizes that polarized light subdues.
Preferably, described second level regulating ring 20 also comprises structure housing 21, rotates this part, can drive second level regulating ring 20 other parts and be rotated simultaneously, handled easily.
In the present embodiment, described filter module has adopted the two-stage resistance coefficient, between first order regulating ring 10 and second level regulating ring 20, adopts the rotational structure that resistance is little to be connected; Between second level regulating ring 20 and structure housing 21, adopt the rotational structure that resistance is large to be connected.
When regulating the less first order regulating ring 10 of resistance and obtain ideal and enter light quantity, because second level regulating ring 20 is larger with the rotary resistance of second level regulating ring 20 than first order regulating ring 10 with the rotary resistance of structure housing 21, so second level regulating ring 20 can not rotate.When regulating second level regulating ring 20, first order regulating ring 10 can synchronously rotate with second level regulating ring 20 because of inertia, thereby realizes that two polariscopes combinations rotate, and realizes that polarized light subdues effect.
In order to regulate more accurately, also comprise and be arranged on locking device 30 on second level regulating ring 20, this locking device 30 is for locking second level regulating ring 20, when regulating first order regulating ring 10, with locking device 30, second level regulating ring 20 is locked, avoid turning to unintentionally second level regulating ring 20, guarantee only to rotate separately first order regulating ring 10, realize entering the control of light quantity.When needs are subdued polarized light and are regulated, the locking of second level regulating ring 20 is untied, during the regulating ring 20 of the rotation second level, first order regulating ring 10 also can synchronous rotary, thereby realizes two filters combination rotations, realizes that polarized light subdues effect.
Further, this filter module also comprises set collar 40, and this set collar 40 is connected with second level regulating ring 20, is provided with the screw thread bayonet socket be connected with camera lens at this set collar 40.
Filter module of the present utility model, by dim light mirror, polariscope and two regulating rings, realizes that single filter module obtains into the effect that light quantity is controlled and polarized light is subdued, simple in structure, handled easily.
The utility model can also have other various embodiments; in the situation that do not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
