Our company can offer variety reflective film devices which are low-scattering, low-absorption and ultra-high laser damage threshold. The devices can work in the wide area of the wave length within 248nm and 3000nm and the size can achieve meter degree maximumly. The damage threshold of the small-aperture devices can be more than  60J/cm2（1064nm ,3ns） and 30J/cm2（1064nm ,3ns）for the big-aperture devices. For those devices whose aperture under φ150mm, the accuracy of reflector shape can be controlled within λ/10 (λ=632.8nm). For those devices whose aperture about Φ400mm, the accuracy of reflector shape can be controlled within λ/4 (λ=632.8nm).
