There are no refractive lenses, only reflective components to the design. For IR application, reflective coatings are a protected gold that gives better than 98% reflectivity from .65 micron (650nm) to 5 micron (5000nm). This design is ideal for infrared astronomy or LIDAR applications. UV-optimized coatings can be provided as well, so please reach out to our technical sales team to discuss UV optimization.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003eIRDK17 is a 17-inch infrared-optimized optical tube with fused silica mirrors\u003c\/li\u003e\n\u003cli\u003eFocal length of 2,939 mm (f\/6.8)\u003c\/li\u003e\n\u003cli\u003eDall-Kirkham optical design with coatings that are optimized to transmit in infrared wavelengths (ultraviolet optimization available)\u003c\/li\u003e\n\u003cli\u003eReady for Delta-T dew prevention\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\nPlaneWave IRDK17 Infrared Optimized\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cbr\u003e\n\u003ch3\u003eManuals \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/istronomyplus.com\/pages\/planewave-warranty\" target=\"_blank\"\u003ePlanewave Warranty (1\u003cspan data-mce-fragment=\"1\"\u003e year for optical coatings and 2 years mechanics and electronics from the date of delivery)\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Planewave","offers":[{"title":"Default Title","offer_id":44152230707429,"sku":"PW-170120Q","price":44020.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/6245\/2965\/files\/planewave-irdk17-infrared-optimized-170120q-astronomy-plus.webp?v=1690492144","url":"https:\/\/istronomyplus.com\/products\/planewave-irdk17-infrared-optimized-170120q","provider":"Astronomy Plus – Telescopes \u0026 Astrophotography Canada","version":"1.0","type":"link"}
