A special-shaped copper block (SSCB) cooling method is proposed, using eutectic indium-gallium alloy as heat transfer medium. The SSCB cooling technology can keep a 550mm-length mirror slope error of 0.2 ¿rad (RMS) under 230 W absorp-tion heat power, showing great advantages in the accura-cy and flexibility for thermal deformation minimization when compared with the traditional ones.
