<strong>The</strong> helium enclosure is a<br />

containment unit that houses<br />

helium and an embedded optical<br />

system in order to improve the<br />

wavefront error with the relative<br />

reduction <strong>of</strong> the thermal gradient<br />

that is typically induced by air. <strong>The</strong><br />

final helium enclosure product is<br />

able to perform optical testing<br />

under an effectively eliminated<br />

thermal gradient, enabling a much closer result to theoretical analysis than<br />

before. This project will also verify the effectiveness <strong>of</strong> helium in mitigating thermal<br />

gradients that are normally seen in air.
