Every mirror listed here has been measured with a full-aperture interferometer before being offered for sale – the report next to each mirror is the real measurement of that particular mirror, not a sample.
In addition to interferometry, our mirrors are also checked with the classical Ronchi and Foucault tests. Ronchi and Foucault images of our mirrors, together with all interferometric test reports we have issued, can be found on the Our Mirror Test Results page.
