Embodiment Construction

[0017] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] This embodiment proposes a tool for detecting the wedge angle of an optical filter, and the tool includes a guide rail and a stage. The section of the guide rail has a stepped structure, such as figure 1 shown. The stage is placed on the stepped structure of the guide rail and can slide along the guide rail. The stage includes a base 1 and a support 2, such as figure 2 As shown, the base 1 is in contact with the guide rail, the support 2 is embedded in the groove on the upper surface of the base 1 , and the upper surface of the support 2 has a positioning groove 3 for fixing the filter. Wherein, both the guide rail and the base are made of metal material, and the supporting part is made of glass material.

Abstract

The invention belongs to the field of optical component testing, and particularly relates to an optical filter wedge angle testing tool and an optical filter wedge angle testing method for quickly testing an optical filter wedge angle. The optical filter wedge angle testing tool comprises a guiderail and an objective table, wherein the objective table is placed on the guiderail and can slide along the guiderail. The objective table comprises a base and a supporting member. The base contacts with the guiderail. The supporting member is embedded into a trough on the upper surface of the base. The upper surface of the supporting member is provided with a positioning trough for fixing the optical filter. According to the optical filter wedge angle testing tool, a plurality of optical filters are kept at the same reference position; when a comparison goniometer is utilized for testing the wedge angle, repeated image finding can be prevented; and through movement of the objective table on the guiderail, quick measurement on the plurality of optical filters can be finished.

Description

technical field [0001] The invention belongs to the field of optical component detection, and in particular relates to a detection tool and a detection method for rapidly detecting the wedge angle of an optical filter. Background technique [0002] The wedge angle parameter is introduced at the end face of the optical filter, which can effectively suppress the degradation of the reflection spectrum caused by oblique incidence. The wedge angle parameter is closely related to the reflection spectrum stability of the filter. In the prior art, when testing optical components, the wedge angle of the optical filter is measured, and a micrometer is usually used to detect the thickness difference of linear dimensions, and then converted into an angle value detection method. This method will generate a large measurement error, which is likely to cause false detection and affect subsequent use. However, when using a comparison goniometer to directly measure the wedge angle, there is...
