LIGHTWEIGHT SiC MIRRORS
Stable optical structures with reduced moving mass.
Lightweighted silicon-carbide mirror structures combine stiffness, low thermal expansion, wear resistance and precision geometry for optical and positioning equipment.
Application and role
SiC square mirrors support lithography and precision optical systems where structural stability and controlled mass are required.
Lightweight architecture
A weight-reduction pattern is developed around optical face support, stiffness, mounting points and manufacturability rather than removing material uniformly.
Thermal and mechanical stability
Low thermal expansion and high stiffness help reduce surface and alignment change when equipment temperature or motion conditions vary.
Geometric precision
Representative SiC mirror structures achieve flatness and parallelism controlled within 1 μm, supporting optical-surface quality and structural stability.
Information for evaluation
Please provide clear aperture, overall envelope, mounting and datum scheme, allowable mass, surface figure or flatness, coating requirement and environmental temperature range.
