This is achieved by attaching a large number of piezoelectric elements symmetrically on both sides of the mirror substrate.<br> A deformable mirror with 18 piezoelectric elements can be deformed into the shape of a sine curve. Up to 9 cycles and surface shape deformation tens of micrometers deep is possible.<br> In a conventional optical system with mirrors of fixed shape, it is impossible to change the focusing size without changing the arrangement of the mirror and sample position (focal position). Using a deformable mirror, the focal area can be changed freely under the diffraction limit without changing the experimental setup of the optical system.<br> Deformable mirrors are also used for wavefront compensation. In the focusing experiment by SPring-8, the world&#8217;s smallest focus size (7 nm) was achieved using a wavefront compensation optical system with a deformable mirror for conventional mirror focusing of the optical system. <\/p>\n<\/div>\n<div class=\"c-col2 -half  u-mb40\">\n    <div class=\"col\">\n        <div class=\"c-image      u-text-center\">  \n            <img src=\"\/assets\/img\/optical\/optical-products\/variable-shape-mirror01.webp\" alt=\"\">\n        <\/div>\n        <div class=\"c-text u-mt10\">\n            <p class=\"u-text-center\">Deformable mirror<\/p>\n        <\/div>\n    <\/div>\n    <div class=\"col\">\n        <div class=\"c-image      u-text-center\">\n            <img src=\"\/assets\/img\/optical\/optical-products\/variable-shape-mirror02.webp\" alt=\"\">\n        <\/div>\n        <div class=\"c-text u-mt10\">\n            <p class=\"u-text-center\">Free shape deformation  by controlling the PZT elements<\/p>\n        <\/div>\n    <\/div>\n<\/div>\n<div class=\"c-col2 -half u-mb40\">\n    <div class=\"col\">\n        <div class=\"c-image      u-text-center\">\n            <img src=\"\/assets\/img\/optical\/optical-products\/variable-shape-mirror03.webp\" alt=\"\">\n        <\/div>\n        <div class=\"c-text u-mt10\">\n            <p class=\"u-text-center\">Deformable mirror focusing system<\/p>\n        <\/div>\n    <\/div>\n<div class=\"col\">\n    \n        <div class=\"c-image      u-text-center\">\n            <img src=\"\/assets\/img\/optical\/optical-products\/variable-shape-mirror04_en.webp\" alt=\"\">\n<\/div><div class=\"c-text u-mt10\">\n    <p class=\"u-text-center\">Controlling focal size using deformable mirror focusing system<\/p>\n<\/div>\n    <\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Product IntroductionDeformable Mirror Deformable mirrors were developed to enable arbitrary deformation of the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":4837,"menu_order":19,"comment_status":"closed","ping_status":"closed","template":"page-optical-detail.php","meta":[],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/pages\/4861"}],"collection":[{"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/comments?post=4861"}],"version-history":[{"count":2,"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/pages\/4861\/revisions"}],"predecessor-version":[{"id":7687,"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/pages\/4861\/revisions\/7687"}],"up":[{"embeddable":true,"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/pages\/4837"}],"wp:attachment":[{"href":"https:\/\/www.j-tec.co.jp\/english\/wp-json\/wp\/v2\/media?parent=4861"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
