We introduce a passive, spring-suspended optics bench for use inside a tabletop vacuum tank. The isolator uses four initially flat cantilever blade springs, loaded to a constant radius of curvature, to attenuate vertical motion. This type of constant curvature blade spring has the advantage of minimizing horizontal\u2013vertical cross coupling around its suspension resonance frequency compared to other blade springs. We use finite element modeling to optimize the geometry of the constant radius blade spring toward maximizing its vertical isolation. We validate our modeled constant curvature blade results using an experimental shaker table setup, with geophone sensing. Our suspension bench achieves a vertical attenuation bandwidth of 3\u201390\u00a0Hz with horizontal\u2013vertical cross coupling below \u221250 dB in the frequency range of 7\u201390\u00a0Hz. Using our model, we found that the cross coupling of the constant curvature blade spring is outperformed at higher frequencies by a pre-bent blade spring, which is flat at its operating point.<\/jats:p>","DOI":"10.1063\/5.0333474","type":"journal-article","created":{"date-parts":[[2026,7,2]],"date-time":"2026-07-02T15:34:13Z","timestamp":1783006453000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Constant radius blade spring suspended bench for vibration isolation"],"prefix":"10.1063","volume":"97","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8957-3662","authenticated-orcid":false,"given":"Koh A.","family":"Baker","sequence":"first","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-8539-7536","authenticated-orcid":false,"given":"John","family":"Winterflood","sequence":"additional","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4566-6888","authenticated-orcid":false,"given":"Carl","family":"Blair","sequence":"additional","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2693-6769","authenticated-orcid":false,"given":"Chiara","family":"Di Fronzo","sequence":"additional","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7951-4295","authenticated-orcid":false,"given":"Li","family":"Ju","sequence":"additional","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5825-2401","authenticated-orcid":false,"given":"Chunnong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Australian Research Council Centre of Excellence for Gravitational Wave Discovery (OzGrav), University of Western Australia , Perth, Western Australia,","place":["Australia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2026,7,2]]},"reference":[{"key":"2026070208464419300_c1","doi-asserted-by":"publisher","first-page":"1639","DOI":"10.1088\/0264-9381\/19\/7\/355","article-title":"Using euler buckling springs for vibration isolation","volume":"19","year":"2002","journal-title":"Classical Quantum Gravity"},{"key":"2026070208464419300_c2","doi-asserted-by":"publisher","first-page":"2407","DOI":"10.1088\/0264-9381\/10\/11\/023","article-title":"Vibration isolation for gravitational wave detection","volume":"10","year":"1993","journal-title":"Classical Quantum Gravity"},{"key":"2026070208464419300_c3","doi-asserted-by":"publisher","first-page":"235004","DOI":"10.1088\/0264-9381\/29\/23\/235004","article-title":"Update on quadruple suspension design for advanced ligo","volume":"29","year":"2012","journal-title":"Classical Quantum Gravity"},{"key":"2026070208464419300_c4","doi-asserted-by":"publisher","first-page":"1631","DOI":"10.1088\/0264-9381\/19\/7\/354","article-title":"The inertial damping of the VIRGO superattenuator and the residual motion of the mirror","volume":"19","author":"The VIRGO Collaboration (Presented by Giovanni Losurdo)","year":"2002","journal-title":"Classical Quantum Gravity"},{"key":"2026070208464419300_c5","doi-asserted-by":"publisher","first-page":"114504","DOI":"10.1063\/1.4967716","article-title":"Small optic suspensions for advanced LIGO input optics and other precision optical experiments","volume":"87","year":"2016","journal-title":"Rev.
