AI Technical Summary

Technical Problem

Traditional filter switching devices are slow and difficult to adapt to dynamic scenes. Frequent manual operation can easily introduce positioning deviations, leading to increased light intensity test errors. Existing devices mostly only support single-dimensional adjustment, making it difficult to adapt to complex optical paths.

Method used

An adjustable light intensity optical filter switching device was designed. Through the combination of support components and switching components, the filter can be flexibly adjusted in three-dimensional space, including the rotation of the support platform, the extension rod extension and retraction, and the rotation of the connecting rod. Combined with the locking mechanism of positioning blocks and fastening bolts, the filter can be quickly loaded and unloaded and accurately positioned.

Benefits of technology

It shortens filter switching time, improves the efficiency of alternating multi-filter testing, adapts to the optical path requirements of different light sources and testing equipment, simplifies the testing process, and is especially suitable for rapid on-site verification.
