Embodiment Construction

[0033] The present invention will be further elaborated below by describing a preferred specific example in detail in conjunction with the accompanying drawings.

[0034] like figure 1 As shown, it is a schematic diagram of the debugging device of the present invention; the part inside the dotted line box is the Karl Fischer optical assembly 10 . The debugging equipment includes an infrared collimator 21 and a detection system capable of measuring the size of the spot and the diameter of the scanning circle, which can display the conditions of the spot and the scanning circle in real time. Among them, the spot 31 is formed by the infrared energy detected by the Karl Fischer optical component 10, and the scanning circle 32 is formed by the rotation of the Karl Fischer optical component 10 around the central axis. Both are detected by the detection system and displayed on the screen.

[0035] Specifically, the Karl Fischer optical assembly 10 receives the infrared parallel ligh...

Abstract

The invention relates to a Cartesian optical assembly assembling and tuning method. A Cartesian optical assembly comprises a main reflective mirror and a secondary reflective mirror to be assembled and tuned. The method comprises: providing a secondary reflective mirror assembly including a plurality of secondary reflective mirrors with different inclination angles; selecting any one of the secondary reflective mirrors in the secondary reflective mirror assembly to match the main reflective mirror; aligning the generatrix of the main reflective mirror with the generatrix of the secondary reflective mirror, and determining whether the diameter of a detected scanning circle of the Cartesian optical assembly satisfies a preset threshold when using the current secondary reflective mirror; and selecting another secondary reflective mirror from the secondary reflective mirror assembly to match the main reflective mirror if the diameter of the scanning circle does not satisfy the preset threshold, and re-conducting the generatrix alignment and the threshold determination of the diameter of the scanning circle, until the secondary reflective mirror with the diameter of the scanning circle satisfying the preset threshold is selected. The method is simple in operation and improves the precision of batch assembling and tuning under the premise of ensuring that the imaging of the Cartesian optical assembly satisfies requirements.

Description

technical field [0001] The invention belongs to the assembly and adjustment technology of Karl's optical components, and relates to the assembly and adjustment technology of conical scanning like Karl's optical system components. Background technique [0002] The Karl Fischer optical system is simple in structure, but requires high adjustment accuracy. At present, there are computer-aided adjustment, turning centering adjustment, center-biased auxiliary adjustment and other methods. However, these methods are suitable for the research-type adjustment of a single component. For efficient batch assembly and adjustment, it is obviously necessary to adopt a specific assembly method in order to improve the efficiency of batch assembly and adjustment while ensuring that the imaging of the optical system meets the requirements. precision. Contents of the invention [0003] The purpose of the present invention is to provide a method for assembling and adjusting the Karl Fischer ...
