Project Description: Athermalization Model for a Five-Element Lens Barrel Assembly The goal of this project is to develop a thermal athermalization model for a five-element refractive lens assembly mounted inside a mechanical lens barrel. The model should account for the thermal expansion of the lenses, spacers, barrel sections, lens cells, and detector/image-plane support structure so that the optical performance can be evaluated over temperature.

Hi, I reviewed your project requirements and I can help you develop a practical, production-ready solution—not just a visually complete CAD model. I’m a mechanical engineer with 13+ years of experience in product design, mechanical systems, CAD development, engineering analysis, and multidisciplinary coordination. Depending on the project, I can support concept development, detailed 3D modelling, assemblies, manufacturing drawings, BOMs, technical calculations, simulations, and fabrication-ready files. My focus is always on clear drawings, realistic detailing, manufacturability, and fast communication throughout the project. I work mainly with SolidWorks, AutoCAD, ANSYS, Revit, Fusion 360, and related engineering tools. You can review similar design and engineering work in my profile. Once I see the available drawings, dimensions, and expected deliverables, I can suggest the most efficient way to proceed. Best regards, Gökay Zaralı

Hello, The key challenge is building an accurate thermal model that captures how the five lens elements, spacers, barrel, cells, and detector support shift with temperature and how those mechanical changes affect optical performance. I’d establish the thermo-mechanical model around the material properties, temperature range, mounting constraints, and optical sensitivity, then evaluate focus/image-plane shift and identify an effective athermalization strategy. Do you already have the lens prescriptions, material CTEs, barrel geometry, and operating temperature range available?
