Description

Filter lens for improving astronomical observation and shooting effects

Technical Field

The utility model relates to a light filter technical field specifically is a light filtering lens for promoting astronomical observation and shooting effect.

Background

The filter has the function of filtering light, and plays a role of seasoning in photography creation. If the filter can be flexibly used, the expression effect of the photographic works can be improved. In black and white photography, the filter can change the tone of the scenery, so that the photographed photo is closer to nature. The color filter is used in color photography, so that the color temperature of a light source and the color of a shot object can be changed or special visual effects can be achieved.

At present, most of lenses for astronomical observation and shooting do not have the function of filtering light, so that when the astronomical observation and shooting are carried out, star points are small, the brightness of starlight is low, the sight is not clear, and orange-yellow spectral light generated by artificial light sources in cities causes light pollution to the astronomical observation and shooting, so that the color cast phenomenon appears on pictures to influence the astronomical observation and shooting effect.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Referring to fig. 1-4, a filter lens for improving astronomical observation and shooting effects comprises a lens frame 1, a lens body 2 and a clamping tube 4, wherein the lens body 2 is installed between the lens frame 1 and the clamping tube 4, the lens body 2 comprises a diffuse transmission layer 21, an optical substrate 22 and an optical coating layer 23, the diffuse transmission layer 21 is arranged on one side surface of the optical substrate 22, and the optical coating layer 23 is arranged on one side surface of the optical substrate 22 far away from the diffuse transmission layer 21.

The optical substrate 22 is a lens made of transparent glass.

The optical substrate 22 is a glass lens made of neodymium and praseodymium.

The diffuse transmission layer 21 is a frosted layer formed by roughening the surface of the glass substrate of the optical base material 22, and the transmitted light diffuses when the light passes through the frosted layer having the roughened surface.

Wherein, the optical coating layer 23 is a transparent metal layer.

Wherein, the inside of lens frame 1 is equipped with lens mounting groove 3, is equipped with the thread groove on the inboard cell wall of lens mounting groove 3, is equipped with on the lateral surface of clamp tube 4 with thread groove assorted screw thread protruding.
