{"product_id":"borg-2591-90fl-objective-lens-bk","title":"BORG 2591 90FL Objective Lens BK","description":"\u003ch2\u003eBORG 2591 90FL Objective Lens BK | A clearly identified objective for a planned optical build\u003c\/h2\u003e\n\u003cp\u003eA complete lens is usually chosen by looking at the finished camera system; this listing is for an objective lens, a component selected as part of an optical design. The BORG 2591 90FL Objective Lens BK is aimed at someone who already has a defined build or replacement requirement, rather than someone simply looking for a general-purpose lens. An objective lens forms an image from incoming light, so its role is central to the instrument it’s specified for. The useful thing here is the exact BORG identification: it gives you a named part to work from when checking a design note, parts record or repair plan. If you’re building, establish the objective’s place in the optical layout first; if you’re replacing a part, match the designation in your documentation before proceeding. This is a specialist component, and its value is in being the specified part—not in broad performance claims.\u003c\/p\u003e\n\u003cdiv class=\"specialist-note\"\u003e\n\u003ch3\u003eSpecialist Note\u003c\/h3\u003e\n\u003cp\u003eThere’s a real limit here: this is a named objective component, not a broad lens recommendation. That’s precisely why it makes sense when your optical plan calls for the BORG 2591 90FL. I’d use “2591” as the part reference against your build sheet or repair record, keeping the selection tied to the exact component rather than a loose description. Keep “90FL” with that reference too; using the full designation makes it easier to follow the part named in your plan. It suits a careful builder or someone maintaining an established optical instrument. For a build, follow the layout; for a replacement, match the written designation before fitting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: BORG\u003c\/li\u003e\n\u003cli\u003eModel: 2591\u003c\/li\u003e\n\u003cli\u003eDesignation: 90FL\u003c\/li\u003e\n\u003cli\u003eProduct type: Objective lens\u003c\/li\u003e\n\u003cli\u003eProduct code: BK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BORG","offers":[{"title":"Default Title","offer_id":57563652129108,"sku":"BG-2591","price":2281.67,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/2493\/3716\/files\/BG-2591_01.jpg?v=1791804910","url":"https:\/\/www.htf-store.com\/de\/products\/borg-2591-90fl-objective-lens-bk","provider":"Hard to Find Camera Store","version":"1.0","type":"link"}
