Kubilay S.
Senior Optical Design Engineer | 17 years Zemax, IR & Zoom Lens Expert
I am a Senior Optical Design Engineer with 16+ years of professional experience developing high-performance optical and electro-optical systems, most recently serving as Head Optical Design Engineer at ASELSAN. Throughout my career, I have personally designed and successfully transitioned 100+ electro-optical systems into production, including optical systems for more than 8 airborne targeting and imaging gimbals. My experience covers VIS, SWIR, MWIR and LWIR systems, continuous-zoom and fixed-focus objectives, common-aperture systems, EOTS, IRST, targeting pods, laser designators, LRF/LST optics, beam expanders, seekers, weapon sights, telescopes, collimators and other demanding optical systems. With nearly 17 years of extensive Zemax OpticStudio experience, I can confidently undertake virtually any optical design challenge—from initial concept and architecture through detailed optimization and final production-ready design. I can also review and improve existing optical designs, identify performance or design issues, and determine whether a design is realistically manufacturable. A particular strength is practical tolerance analysis: rather than applying theoretical tolerances, I evaluate designs using realistic manufacturing, assembly and alignment capabilities to achieve the best balance between optical performance, production yield and cost. My support can include: • Complete optical design from specifications to production-ready solution • Review, optimization and troubleshooting of existing optical designs • Realistic tolerance analysis and manufacturability assessment • Athermalization and environmental performance analysis • Stray-light analysis • Optical drawings and manufacturing documentation • Optical supplier evaluation and manufacturing support • Independent design reviews and technical consultancy Having worked directly with optical manufacturers for many years, I approach optical design not only from a simulation perspective, but also with a strong understanding of how optics are actually fabricated, coated, measured, assembled and tested. Whether you need a complete new optical system, an independent expert review of an existing design, or help turning a promising optical concept into a manufacturable product, I can provide senior-level support from concept through production.
