  • Abstract
    All-dielectric micromirrors are reported that maintain their shape to within λ/60 at 633 nm over a range of 30 C, limited by the measurement apparatus. In tandem with the experimental results, thermally invariant coating design is discussed along with thermal expansion results from some common dielectric coating materials
