range.<\/p>\n<p>These anti-reflection films are designed for an incident range of 0 to 30 degrees (0.5NA).<\/p>\n<p>For optical systems intended for large incidence angles, conventional coatings optimized for 45\u00b0 can be considered, and these AR films are effective from 25\u00b0 to 52\u00b0.<\/p>\n<p>The left diagram shows the properties of these standard coatings as a function of the wavelength. The broadband coating has a typical absorption of 0.25%, which is not indicated on the reflectance curve.<\/p>\n\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\n\t\n\n\n<style>\n#row-1801875116 > .col > .col-inner {\n  padding: 20px 0px 0px 0px;\n}\n<\/style>\n<\/div>\n\n\t\t<\/div>\n\n\t\t\n<style>\n#section_330117398 {\n  padding-top: 30px;\n  padding-bottom: 30px;\n}\n#section_330117398 .ux-shape-divider--top svg {\n  height: 150px;\n  --divider-top-width: 100%;\n}\n#section_330117398 .ux-shape-divider--top .ux-shape-fill {\n  fill: rgb(249, 249, 249);\n}\n<\/style>\n\t<\/section>\n\t\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>PCV074, Plano-Concave Lenses, coated SWIR AR Coating, 1050-1700nm, made from H-K9L (BK7) optical glass compliant RoHS<\/li>\n<li>This Plano-concave lens with a diameter of 50.80mm, has different focal lengths for you to choose from, f-75mm, f-100mm, f-150mm.<\/li>\n<\/ul>\n","protected":false},"featured_media":3716,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[37,40,66,73],"product_tag":[],"class_list":{"0":"post-4250","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-lenses","7":"product_cat-plano-concave-pcvlenses","8":"product_cat-k9-plano-concave-lenses","9":"product_cat-swir-ar-coating-1000-1650nm-k9-plano-concave-lenses","11":"first","12":"instock","13":"shipping-taxable","14":"purchasable","15":"product-type-variable"},"_links":{"self":[{"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/product\/4250","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/comments?post=4250"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/media\/3716"}],"wp:attachment":[{"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/media?parent=4250"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/product_brand?post=4250"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/product_cat?post=4250"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.etaoptics.com\/ko\/wp-json\/wp\/v2\/product_tag?post=4250"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
