Abstract
The utility model discloses a magnifier used for an image sensor of a digital camera which belongs to the field of apparatus cleaning and is suitable for observing the dust on the lens surface of an apparatus, in particular to observing the dust on the surface and in the cavity of the image sensor of a digital single lens reflex camera. The utility model aims at eliminating the halo disturbances generated on the surface of the CCD/CMOS surface of the digital camera and more clearly observes the dust and cleaning degree on the surface of the image sensor of the digital single lens reflex camera. The technical scheme that a magnifier is provided with double layers of flat convex lenses to be matched with a light source is adopted. The magnifier is characterized in that the magnifier lens is a combined lens formed by two flat convex lens with different curves; when the planes of the two flat convex lenses are opposite, the amplifying times of the combined lens are more than or equal to 5; the light guide part of the light source is a foggy LED(6); the diameter of the LED is more than or equal to 5mm. The magnifier is simple in structure and effectively eliminates the halo disturbances generated on the surface of the CCD/CMOS surface of the digital camera.
Description
Technical field:
The magnifier that a kind of digital camera image sensor is used belongs to the instrument cleaning applications, is applicable to the dust on the optical viewer minute surface, is applicable to especially to observe dust in digital slr camera image sensor surface and the chamber.
Background technology:
Digital camera record image is not with traditional photosensitive material film, but with the sensor of opto-electronic conversion, CCD or CMOS.Digital slr camera is brought dust in air into fuselage interior easily when changing camera lens, and is attached to the image sensor surface, and dust can cause the fleck of imaging, destroys image quality.Owing to do not observe the micronic dust dust with eyes, so existing inspection method is to differentiate to observe the image of taking, such way is not easy accurately, in time to find dust, and the shortcoming that can not find the image sensor surface dirt.Though can be by initiatively light source magnifier observation dust be arranged, because the special construction of image sensor, light can produce halation on its surface and can't see clearly, can not effectively observe.
Summary of the invention:
The utility model proposes the magnifier that a kind of digital camera image sensor is used, its objective is and eliminate the halation that digital camera CCD/CMOS surface produces, more the dust and the clean level on the digital slr camera image sensor of clear view surface.
The technical solution adopted in the utility model is: magnifier has the cooperation of double-deck plano-convex lens sheet and light source.
The magnifier that a kind of digital camera image sensor is used, comprise enlarging lens, light source, visor and housing, enlarging lens, light source and visor are fixed on the housing, it is characterized in that: the compounded plate that described enlarging lens is made up of small curve plano-convex lens sheet and deep camber plano-convex lens sheet, the plane of two plano-convex lens sheets is relative, the enlargement factor of compounded plate is more than or equal to 5 times, the light guide of described light source is vaporific LED, the diameter of LED is greater than or equals 5 millimeters, led light source is fixed on the housing of enlarging lens front end, and the edge of close camera lens interface.
The magnifier that above-mentioned a kind of digital camera image sensor is used, the enlargement factor that it is characterized in that described compounded plate is 5 times, and the diameter of vaporific LED is 5 millimeters.
The magnifier that aforesaid a kind of digital camera image sensor is used is characterized in that the deep camber plano-convex lens sheet of described compounded plate and the enlargement factor of small curve plano-convex lens sheet are respectively 2 times and 3 times.
The magnifier that above-mentioned a kind of digital camera image sensor is used is characterized in that the plano-convex lens sheet of described deep camber can move.
The magnifier that above-mentioned a kind of digital camera image sensor is used is characterized in that described light source is 1-4 vaporific LED.
The magnifier that above-described a kind of digital camera image sensor is used is characterized in that the end face of described housing has ring groove to cooperate with the flange of digital camera lens interface surface.
The utility model is simple in structure, has eliminated halation, and the big plano-convex lens sheet of curvature can move, and when making magnifier be used as the cleaning light source, enough spaces is arranged.Reached the purpose of the digital slr camera image sensor of clear view surface cleaning degree.
Description of drawings:
Fig. 1 is the front view of magnifier.
Fig. 2 is the upward view of magnifier.
Fig. 3 is that magnifier cooperates figure with the flange of digital camera lens interface surface.
Specific embodiments:
Fig. 1-3 has shown the structure of the magnifier that a kind of digital camera image sensor is used and the relation of protecting mutually between the part.It mainly comprises enlarging lens group, active light source, front end ring groove structure;
Five times enlarging lens group is combined by two plano-convex lens sheets (3,5), and the enlargement factor of small curve plano-convex lens sheet 3 is 3 times, and deep camber plano-convex lens sheet 5 enlargement factors are 2 times, and the plano-convex lens sheet 5 that its mean curvature is big can take out from mobile hole 4;
Initiatively light source is the complete vaporific highlighted led light source 6 of 5MM by 4 diameters, and is equipped with corresponding power supply formation;
The ring groove 7 and the digital camera 8 lens interface place metal outward flange sizes of housing 2 front ends cooperatively interact, to determine the relative position of magnifier and digital camera.
The magnifier that this is routine simple in structure, by enlarging lens, initiatively light source structure and with the cooperation position of digital camera interface, eliminated the halation that digital camera CCD/CMOS surface produces effectively.Reached the purpose of the digital slr camera image sensor of clear view surface cleaning degree; In addition, the plano-convex lens sheet 5 that curvature is big removable vacateed the space for remove image sensor surface dust with cleaning rod, and the observation that people can be by visor 1 and small curve plano-convex lens sheet 3 at this moment is the operation cleaning rod down.
