Máquina pulidora de óptica de germanio: El paso final para lentes IR listas para producción
A germanium lens can pass every upstream check — correct radius, right thickness, clean edges — and still get rejected at final inspection. The reason is almost always surface finish. If the polished surface doesn’t reach Ra < 5 nm, IR transmission drops at 8–12 μm, and for thermal imaging applications, that means a rejected […]
