{"product_id":"zeiss-10x-triplet-loupe","title":"Zeiss 10X Triplet Loupe","description":"\u003cp\u003eThe Zeiss 10X Triplet Loupe is a professional-grade magnifier engineered to deliver an exceptionally large field of view with outstanding optical clarity. Designed and manufactured by Carl Zeiss, this loupe is built for jewelers, gemologists, and precision craftspeople who demand the highest standard in optical performance. The model reference is Einschlaglupe D 40, part number 205171-9200.000 057L09.\u003c\/p\u003e\u003cp\u003eAt the heart of this loupe is a 13mm diameter glass lens with a field of view that spans nearly the entire 13mm aperture — a distinction that sets it apart from competing triplets that may offer larger lenses but cannot match this usable field of view. The lens features an anti-reflection coating to reduce glare and improve contrast, ensuring clean, accurate color rendition during stone grading, hallmark reading, or detail inspection.\u003c\/p\u003e\u003cp\u003eThe aplanatic-achromatic lens system design eliminates distortion and chromatic aberration across the full field of view, including the peripheral zones — the result of Carl Zeiss's advanced optical research. As noted in the included owner's manual: \u003cem\u003e\"The field of view is therefore exceptionally large for the magnification power… the aplanatic-achromatic design of the lens systems provides you with a field of view which is practically free of distortion and chromatic aberrations right into the peripheral zones.\"\u003c\/em\u003e\u003c\/p\u003e\u003cp\u003eThe optical assembly is housed in a durable plastic casing that provides protection against accidental drops, making it a reliable companion at the bench or in the field. When folded, the loupe measures a compact 25mm × 38mm × 15.5mm, fitting easily in a pocket or tool roll. A 2.5mm hole through the rivet allows the loupe to be hung from a chain for convenient wear or storage.\u003c\/p\u003e\u003cp\u003eThis is the only 10X triplet offered by Otto Frei that includes an owner's manual — a reflection of the confidence Carl Zeiss places in this instrument as a high-performance optical product.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e10X magnification with aplanatic-achromatic triplet lens system\u003c\/li\u003e\n\u003cli\u003e13mm diameter glass lens with field of view spanning nearly the full 13mm aperture\u003c\/li\u003e\n\u003cli\u003eAnti-reflection coating for reduced glare and improved contrast\u003c\/li\u003e\n\u003cli\u003eDistortion-free and chromatic aberration-free performance to the peripheral zones\u003c\/li\u003e\n\u003cli\u003eDurable plastic casing for protection against accidental impact\u003c\/li\u003e\n\u003cli\u003eCompact folded dimensions: 25mm × 38mm × 15.5mm\u003c\/li\u003e\n\u003cli\u003e2.5mm rivet hole for chain suspension\u003c\/li\u003e\n\u003cli\u003eIncludes owner's manual — unique among 10X triplets in this catalog\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eCarl Zeiss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eModel Reference\u003c\/th\u003e\n\u003ctd\u003eEinschlaglupe D 40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003e205171-9200.000 057L09\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMagnification\u003c\/th\u003e\n\u003ctd\u003e10X\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens Diameter\u003c\/th\u003e\n\u003ctd\u003e13mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLens Type\u003c\/th\u003e\n\u003ctd\u003eTriplet, aplanatic-achromatic, anti-reflection coated glass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHousing Material\u003c\/th\u003e\n\u003ctd\u003ePlastic\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFolded Dimensions\u003c\/th\u003e\n\u003ctd\u003e25mm × 38mm × 15.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRivet Hole Diameter\u003c\/th\u003e\n\u003ctd\u003e2.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Carl Zeiss","offers":[{"title":"Default Title","offer_id":43579703427286,"sku":"129.709","price":135.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/zeiss-10x-triplet-loupe-otto-frei.jpg?v=1719958500","url":"https:\/\/www.ottofrei.com\/ja\/products\/zeiss-10x-triplet-loupe","provider":"Otto Frei","version":"1.0","type":"link"}
