These lenses stand up well to harsh environments and we offer the most popular sizes with Anti-Reflection Coatings. Germanium is subject to thermal runaway, meaning that the transmission decreases as temperature increases. As such, these lenses should be used at temperatures below 100\u00b0C. Germanium\u2019s high density (5.33 g\/cm3) should be considered when designing for weight-sensitive systems. The Knoop Hardness of Germanium is 780, making it ideal for IR applications requiring rugged optics.<\/p>\n<p>GERMANIUM LENSES<\/p>\n<ul>\n<li>High Index of Refraction<\/li>\n<li>Minimal Chromatic Aberration Due to Low Dispersion<\/li>\n<li>Perfect for Rugged IR Applications<\/li>\n<li>Popular Sizes Available with AR Coating from 3-12\u03bcm<\/li>\n<\/ul>\n<p>Factory Standard\u2013 Contact us for manufacturing limit or custom specifications<\/p>\n<ul>\n<li>Substrate Material: Ge (Germanium)<\/li>\n<li>Diameter: \u00a05mm-350mm<\/li>\n<li>Shape: Spherical Plano-Concave, P-Convex, Concave-Convex or Aspheric<\/li>\n<li>Focal length: +\/-1%<\/li>\n<li>Surface Quality: 20-10(after coating)<\/li>\n<li>Surface figure: l\/4 @ 633nm<\/li>\n<li>Clear Aperture: &gt;85% of central dimension<\/li>\n<li>Antireflection Coating: @ 3-12 um<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Our Germanium lenses are perfect for Mid-Infrared  &hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[2],"tags":[36],"_links":{"self":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts\/147"}],"collection":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/comments?post=147"}],"version-history":[{"count":0,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/posts\/147\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/media?parent=147"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/categories?post=147"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.shalomeo.com\/blog\/wp-json\/wp\/v2\/tags?post=147"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
