Embodiment Construction

[0018] A lens for narrow-band imaging observation of space environment according to the present invention will be described in detail below with reference to the drawings and embodiments.

[0019] Such as figure 1 As shown, a lens for narrow-band imaging observation of a space environment according to the present invention includes: a first lens group 1 , a narrow-band filter 3 , a diaphragm 4 , a second lens group 2 and a lens barrel 6 . The first lens group 1 , the narrow-band filter 3 , the diaphragm 4 , and the second lens group 2 are sequentially arranged in parallel in the lens barrel 6 along the incident direction of the light path. The first lens group 1 is used to adjust the incident light angle in the space environment, so that when the light enters the narrow-band filter 3, it meets the requirements of the incident angle, and cooperates with the narrow-band filter 3 to realize Narrow-band filtering: the second lens group 2 is used for re-imaging the light emitted b...

Abstract

The invention provides a camera lens for space environment narrow-band imaging observation. The camera lens comprises a lens cone (6), a first lens set (1), a second lens set (2), a narrow-band filer plate (3) and a diaphragm (4), wherein the first lens set (1), the narrow-band filter plate (3), the diaphragm (4) and the second lens set (2) are successively arranged in the lens cone (6) in parallel in an incidence direction of a light path; the first lens set (1) is used for regulating an angle of light which comes into the space environment, so that the light is adaptive to an incidence angle requirements while coming into the narrow-band filer plate (3), and is matched with the narrow-band filer plate (3) to realize narrow-band filtering; the second lens set (2) is used for performing re-imaging processing on light which comes out of the narrow-band filter plate (3) to correct lens aberration errors to obtain low distortion imaging effects. The camera lens is suitable for performing TDI (Time Delay and Integration) imaging on a faint light source with bandwidth of several nanometers in the space environment.

Description

technical field [0001] The invention relates to the field of imaging technology, in particular to a lens for narrow-band imaging observation of space environment. Background technique [0002] In the field of space science exploration and application, when carrying out TDI (time delay integration) imaging observations on weak light sources with a bandwidth of several nanometers in the space environment, it is necessary to be able to adapt to the space environment and withstand radiation, and to be able to filter and image light of several nanometers low distortion lens. At present, there is no lens design that can be directly applied to this occasion in the prior art. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the existing imaging lens cannot be directly used in the space environment to carry out TDI imaging on a weak light source with a bandwidth of several nanometers. The present invention provides a lens for nar...
