Zusammenfassung: | PROBLEM TO BE SOLVED: To suppress differences in temperature change characteristics between a plurality of optical elements caused by, for example, optical radiation or suppress differences in temperature in one optical element.SOLUTION: The adjusting device 28, for temperature change characteristics of a lens L3, includes: a lens holder 36A that retains the lens L3; temperature control blocks 38A1-38A4 that store a piping section 18B through which temperature-controlled liquid Co passes; and block controllers 50A-50D that adjusts a heat transfer time constant or thermal resistance between the lens holder 36A and the temperature control blocks 38A1-38A4. |
