Abstract
The invention discloses a filter lens. The filter lens comprises a lens. The filter lens is characterized in that a lens surface of one side of the lens is plated with a filter coating. The other lens surface of the lens also can be plated with an antireflection film. The filter coating can be a broadband band-pass filter coating or a narrow-band band-pass filter coating or a front cut-off filter coating or a rear cut-off filter coating. By means of the filter lens, the filter coating can be arranged on different surfaces of the lens. The filter lens has the function of the lens and the function of a light filter, and the biggest advantage is that the functions normally achieved through two lenses can be achieved by one optical lens. By the combination of the lens function and the light filter function, cost is reduced, the structure is simplified, and the lens can be more miniaturized.
Description
Technical field
The present invention relates to a kind of optical lens, particularly a kind of filter lens.
Background technology
Present optical lens is all without filter coating, as a camera lens, often all filter set is combined in camera lens in the time will realizing filtering functions, realize the effect that not only filters but also focus on, but this structure is difficult to make camera lens microminiaturized, and has also brought complicated structural relation.
Summary of the invention
The objective of the invention is to provide in order to solve above-mentioned the deficiencies in the prior art a kind of simple in structure, easy to use, the filter lens that can simplify lens construction.
To achieve these goals, the filter lens that the present invention is designed comprises lens, it is characterized in that being coated with filter coating on the mirror surface of lens one side.Also can be coated with antireflecting film on another mirror surface of lens.All can be coated with filter coating on the mirror surface of the both sides of lens.Described filter coating can be broadband bandpass filters, arrowband bandpass filters, front cut-off light filtering films, rear cut-off light filtering films.Be provided with antireflecting film and can reduce reflection on lens, improve the transmitance of light, and realize simultaneously focusing on.
Filter lens provided by the invention, filter coating can be arranged on the not coplanar of lens.Plate various functional membranes at lens, can see through selectively required light, shield other unwanted light, reach the purpose of accurate detection.
Filter lens provided by the invention, have outside the function that lens have, also possesses the function that optical filter has, maximum benefit is the function that routine needs two arrangement of mirrors heads to realize can be realized on an optical lens, the combination of lens function and optical filter function, reduced cost, simplified the structure, made more miniaturization of camera lens.
Description of drawings
Fig. 1 is the structural representation of embodiment 1;
Fig. 2 is the structural representation of lens one side mirror face plating filter coating opposite side minute surface coated with antireflection film.
In figure: lens 1, filter coating 2, antireflecting film 3.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Embodiment 1:
As shown in Figure 1, the filter lens that the present embodiment provides comprises lens 1, is coated with filter coating 2 on the mirror surface of lens 1 one sides, and described filter coating can be broadband bandpass filters, arrowband bandpass filters, front cut-off light filtering films or rear cut-off light filtering films.
Embodiment 2:
As shown in Figure 2, the filter lens that the present embodiment provides comprises lens 1, is coated with filter coating 2 on the mirror surface of lens 1 one sides, is coated with antireflecting film on another mirror surface of lens 1, further improves the transmitance of light, reduces reflection, and realizes simultaneously focusing on.
Embodiment 3:
The filter lens that the present embodiment is described can all be coated with filter coating on the mirror surface of the both sides of lens 1.Plate the broadband bandpass filters as a side, opposite side plating cut-off light filtering films.
