    Should every lens receive a functional optical test?<\/h3>\n

    Not necessarily. A capable process may use validated dimensional or metrology proxies plus scheduled functional checks. Safety-critical or extremely sensitive optics may require more extensive screening.<\/p>\n

    When should insert correction begin?<\/h3>\n

    After the molding process and measurement method are stable and the same directional error repeats across sufficient samples. Correcting steel before that point can compensate for noise rather than the mold.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"

    A molded lens can meet its diameter and center-thickness dimensions and still miss its optical target. In lens injection molding, form error, decenter, surface replication, residual stress and assembly load all influence the final beam. The practical question is therefore not simply whether plastic can reproduce the CAD model, but whether the molded and assembled […]<\/p>\n","protected":false},"author":1,"featured_media":3758,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3724","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts\/3724","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/comments?post=3724"}],"version-history":[{"count":0,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/posts\/3724\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/media\/3758"}],"wp:attachment":[{"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/media?parent=3724"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/categories?post=3724"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jcinjectionmolding.com\/vi\/wp-json\/wp\/v2\/tags?post=3724"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
