{"product_id":"zwo-uv-ir-blocking-filter-2","title":"ZWO UV\/IR Blocking Filter - 2\"","description":"\u003cp\u003eThis filter blocks out ultraviolet and infrared light which improves the imaging and viewing on many telescopes. This is especially useful for camera sensor chips that have no UV protective AR glass and are sensitive to UV and IR light.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003eThe filter is used for luminance imaging and for Moon and Planet images. Infrared or IR light is invisible to the human eye, and so even though most telescopes are not designed to focus IR light, it does not matter when you are using your telescope visually.\u003c\/p\u003e\n\u003cp\u003eHowever, when you add a camera to the mix, its a whole other story! Unlike the human eye, a silicon sensor is very sensitive to light in the infrared portion of the spectrum, and that is a problem and can cause blurring in your images. That means your nice, sharp visual light image is degraded by the addition of the infrared layer. This problem can easily be solved by blocking the infrared, and the ZWO IR-Cut filter will do just that.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003cstrong\u003eSpecs:\u003c\/strong\u003e\u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFilter type: UV\/IR Cut Filter\u003c\/li\u003e\n\u003cli\u003eFilter thickness: 2 mm glass thickness\u003c\/li\u003e\n\u003cli\u003eConnection: 1.85\" filter thread (outside)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003col\u003e\u003c\/ol\u003e","brand":"ZWO","offers":[{"title":"Default Title","offer_id":40748809978051,"sku":"ZWOIRC2","price":75.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0596\/1924\/6275\/products\/ZWOUVIRFilter2_2.jpg?v=1632411417","url":"https:\/\/www.horizonastronomy.ie\/en-mc\/products\/zwo-uv-ir-blocking-filter-2","provider":"Horizon Astronomy • Telescope Center","version":"1.0","type":"link"}
