Vacuum Canister

Improve Frequency Response of Deformable Mirrors!

Our mirrors can be placed under vacuum while operating in our compact, affordable vacuum canister. The canister can be fitted with a plano-plano window or a plano-concave weak lens/window (designed to compensate for the membrane focus at medium stroke settings). The frequency response curves can be seen in these depictions of our results for three of our most popular mirror sizes:

Negative Lens Window

A corrective lens can be strategically placed to counteract the "pull-only" nature of electrostatically-actuated deformable mirrors. Our lenses are made of BK7 with a broadband anti-reflective coating for use at wavelengths of 450nm to 650nm. This item can easily be used in place of the "window" of the AgilOptics Vacuum Canister. The typical focal lengths for our most popular mirror sizes (with lens correction) are as follows:
