Description :

ZT442/532rpc is ultra-flat laser dichroic mirror with dual band wavelength range from 435nm-450nm, 529nm-538nm. The ZT442/532rpc dichroic beamsplitter mirror reflects lasers between 435-450nm and 529-538nm.

Sputtered thin-films exert stress on glass and fused silica substrates and warp them into varying degrees of curvature. Chroma has learned how to control this to a large extent by developing a proprietary manufacturing method which minimizes surface curvature. Another factor which reduces surface curvature is the use of thicker substrates which provide greater stiffness and therefore more resistance to the stress exerted by these coatings. Combining these two elements allows Chroma to specify levels of dichroic surface flatness according to thickness.
