Numerical study on thermal deformation characteristic of water-cooled mirror with interdigitated channels

Fabrication of silica glass microchannel reflectors by 3D printing and UV-curing

“…Consequently, maintaining the mirror temperature within a specific range is crucial. Water-cooling emerges as the most effective and widely adopted approach to mitigate thermal deformation, offering advantages such as high heat dissipation rate, affordability, and environmental friendliness [4][5][6]. However, the fabrication of water-cooling reflectors with internal micro-channels is challenging, especially for silica glass, which is characterized by high brittleness and low fracture toughness.…”
