Avantier’s precision-engineered SWIR hyperspectral lens delivers crisp imaging across 1000–2500 nm, combining high transmittance and thermal stability for reliable, high-resolution analysis.
Category: Freeform Optics
The Freeform Optics case study category highlights how Avantier uses advanced freeform surfaces to solve challenging imaging and packaging problems in modern optical systems. These case studies feature projects such as off-axis four‑mirror space camera designs that deliver ultra‑wide 70° fields of view with excellent image quality from compact sensor formats. Readers can see how freeform mirrors enable tighter packaging, weight reduction, and improved performance for demanding spaceborne and airborne platforms. Each case study explains the full development flow, from optical design and tolerance analysis through precision fabrication, metrology, and system-level integration. Topics include the choice of substrates, machining and polishing strategies, and alignment considerations unique to freeform components. The examples demonstrate how freeform optics help correct complex aberrations and reduce element count compared with traditional symmetric designs. This category is a valuable resource for engineers and program managers exploring freeform technology for Earth observation payloads, compact imaging systems, or other high‑performance applications. By reviewing these real‑world projects, readers gain insight into the trade‑offs, risks, and rewards associated with adopting freeform optics—and how Avantier’s experience can help bring these designs into manufacturable, reliable hardware.
