Abstract

This utility model discloses a lens replacement structure and a light source device, belonging to the field of optical equipment technology. It includes a support frame with a fixing frame bolted to the top. The device comprises a bracket, an attenuator frame, a lens attenuator, a pressure ring, and a mounting cavity. By squeezing the handle, the attenuator frame is aligned with the mounting cavity inside the bracket, and then smoothly pushed into the cavity. The position of the attenuator frame is adjusted to achieve a stable connection between the attenuator frame and the bracket. Simultaneously, the pressure ring provides compression protection for the lens attenuator, ensuring coaxial alignment between the lens attenuator and the plano-convex lens, preventing misalignment. This allows for the installation or replacement of the lens attenuator, ensuring the accuracy and stability of infrared optical experiments. The replacement of the lens attenuator requires no complex tools, significantly simplifying the process and improving maintenance efficiency. Furthermore, the compatibility with various lens attenuator models allows the light source device to flexibly handle different light intensity scenarios.
