In each episode, we talk about a different topic and try to answer the most common questions we receive about it. Today, we are going to talk about the term fogproof.<\/p>\n<p align=\"LEFT\">Fogging occurs when optics experience a rapid change of temperature. If there&#8217;s air on the inside of the optics that contains moisture, internal condensation will occur. The moisture starts forming small fog droplets inside the optics. So if the optics aren&#8217;t fogproof, they will not be usable in winter or in other situations where they would encounter substantial temperature differences.<\/p>\n<p align=\"LEFT\">Fogproof optics contain no moisture that could cause fogging. This is usually achieved by replacing the air with argon or nitrogen.<\/p>\n<p align=\"LEFT\">All premium <a href=\"https:\/\/www.optics-trade.eu\/en\/riflescopes.html\">riflescopes<\/a>, <a href=\"https:\/\/www.optics-trade.eu\/en\/dot-sights\/tube-dot-sights.html\">tube red dot sights<\/a>, <a href=\"https:\/\/www.optics-trade.eu\/en\/binoculars.html\">binoculars<\/a>, and <a href=\"https:\/\/www.optics-trade.eu\/en\/monoculars.html\">monoculars<\/a> are fogproof. Nitrogen is used in most cases and the use of argon is quite rare. All optical products that are fogproof are also waterproof.<\/p>\n<p align=\"LEFT\">The only types of optics that can&#8217;t be made fogproof are extendable monoculars and spotting scopes.<\/p>\n<p align=\"LEFT\">Argon atoms are bigger than nitrogen molecules, so it&#8217;s harder for them to escape. If there is a normal sized leak, both gasses would escape and air would replace them. Both work the same and there isn&#8217;t a \u201ebetter\u201c one, because they don&#8217;t affect optical properties.<\/p>\n<p align=\"LEFT\">We would like to thank you for your time.

To prevent the formation of\u00a0<strong>inside fogging<\/strong>\u00a0they\u2019re often filled with\u00a0<strong>dry gas<\/strong>\u00a0\u2013 either nitrogen or argon which contain no moisture.<\/em><\/p>\n<p style=\"text-align: center; padding-left: 30px;\"><em>To keep the gas intact on the inside, the optics have to be\u00a0<strong>properly sealed<\/strong>, which is why all <\/em>fogproof<em> optical products are also\u00a0<strong>waterproof<\/strong>.<\/em><\/p>\n<p style=\"text-align: center; padding-left: 30px;\"><em>It\u2019s important to keep in mind that <\/em>fogproof<em> means that it\u2019s to prevent fogging on the inside of the optics, not on the outside. If your outside surface of the lenses fogs up due to temperature differences or humidity just allow them to adjust back \u2013 do not wipe the condensation off as it can be damaging to the glass surface and its coatings.<\/em><\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.podbean.com\/media\/player\/6g58s-950479-pb?from=share&amp;skin=1&amp;share=1&amp;fonts=Helvetica&amp;download=0&amp;skin=1&amp;btn-skin=107\" width=\"100%\" height=\"100\" frameborder=\"0\" scrolling=\"no\" data-name=\"pb-iframe-player\"><\/iframe><\/p>\n<p><strong>Products mentioned:<\/strong><br \/>\nFogproof riflescopes: <a href=\"https:\/\/www.optics-trade.eu\/en\/riflescopes\/shopby\/special_features-fogproof.html\">https:\/\/www.optics-trade.eu\/en\/riflescopes\/shopby\/special_features-fogproof.html<\/a><br \/>\nFogproof binoculars: <a href=\"https:\/\/www.optics-trade.eu\/en\/binoculars\/shopby\/special_features-fogproof.html\">https:\/\/www.optics-trade.eu\/en\/binoculars\/shopby\/special_features-fogproof.html<\/a><br \/>\nFogproof spotting scopes: <a href=\"https:\/\/www.optics-trade.eu\/en\/spotting-scopes\/shopby\/special_features-fogproof.html\">https:\/\/www.optics-trade.eu\/en\/spotting-scopes\/shopby\/special_features-fogproof.html<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Welcome to Optics Trade debates.
