These lenses aim to reduce the need for immersion oil by providing a dry image that claims to be 95% as sharp as an oil-based image.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eAdvantages\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThere are a few obvious advantages to a dry 100x lens.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe main advantage is efficiency. If you don’t have to prepare slides with oil or to clean your equipment after use, you’ll save a lot of time that can be spent more productively.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eYou’ll be able to swap slides much faster too, allowing you to get faster results.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eMaintenance\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWhen you’re working without oil, there’s no longer a risk of oil-related damage, always a hazard if your equipment is improperly cleaned or maintained.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIt’s also common for people to accidentally dunk their 40x non-oil lens into the immersion oil, which can cause lasting harm and require professional servicing.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eSo dry lenses can help keep repair and replacement costs to a minimum.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eSave $$ on oil\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eIt’s obvious, but you won’t need to buy immersion oil. Over time, this could be a cost-effective option.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eDisadvantages\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThere are some downsides to dry 100x objectives too.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eLower resolution\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe most important consideration is the lower resolution of dry lenses.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThey have a lower numerical aperture value (NA) than their oil-based equivalents, with a maximum NA of 0.95.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eNA is a measure of the ability of a lens to resolve fine detail – lower values mean a lens is less capable of seeing detail at higher magnifications. Essentially, it’s the resolution of the lens.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eWhen working at higher magnifications, such as 1000x, resolution is important. If your lens doesn’t have enough resolution, your image will be blurry and distorted.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eAs a rule of thumb, the NA of a lens multiplied by 1000 gives you the maximum magnification of that lens, beyond which you’ll get lower visual quality.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e \u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e100x dry lenses often have an NA of 0.85, which means their image quality starts to degrade beyond 850x magnification. At 1000x magnification, the image is not as clear and detailed as it could be.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eOil lenses with an NA of 1 or above would have the resolution to see the detail in that last 150x magnification.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThe image quality of a dry lens is still good, but not as good as it could be. Whether that’s an issue comes down to your circumstances and preferences.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003e\u003cb\u003eConclusion\u003c\/b\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eThere’s no substitute for the resolution of an oil lens. If image quality is paramount, you shouldn’t consider a 100x dry lens.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\"\u003eHowever, if your purpose allows for lower quality images, dry lenses could save you a lot of time and mess. The potential productivity gains are huge, and you can say goodbye to the ever-present worry of oil damage.\u003c\/p\u003e","brand":"animaldirectgroup","offers":[{"title":"Default Title","offer_id":47711934382267,"sku":"V1CLINIC100D","price":442.2,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0713\/7466\/7963\/files\/Microscope_52ffefdd-ed12-41ca-a98f-40e4b174a5b1.png?v=1776394754","url":"https:\/\/animaldirectgroup.com\/products\/v1-clinic-microscope-100x-semiplain-dry-objective","provider":"animaldirectgroup","version":"1.0","type":"link"}
