MIC TECH offers high precision aspheric surface (1/50λ RMS, λ is 12nm) is hard to meet the requirements of many application scenarios (such as laser communication, X-ray focused imaging, etc.), and the market is in urgent need of ultra-high precision aspheric surfaces (such as less than 1/100λ RMS, λ is 632nm). Through the process optimization, magnetorheological parameter compensation and other processing methods, assisted by high-precision interference detection and distortion correction technology, the development of ultra-high precision aspheric mirror less than 1/100λ RMS is stably achieved, and the maximum reaches 1/128λ RMS, quickly gain recognition from high-end users.
