It is particularly suited for detecting surface defects such as scratches, concavity, convexity, and fine irregularities, making it ideal for precision surface analysis.\u003c\/p\u003e\n\u003cp\u003eWith an infinity-corrected optical design and correction across the visible wavelength range (436–656 nm), this objective delivers sharp, high-contrast imaging in both bright and dark field modes. The long 34 mm working distance provides excellent clearance, enabling inspection of larger components or uneven surfaces with ease.\u003c\/p\u003e\n\u003cp\u003eDesigned for use with MF-U and Hyper MF-U microscope systems, the BD Plan Apo 7.5X offers reliable performance for industrial and laboratory inspection tasks.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eSuitable for Bright Field and Dark Field inspection\u003c\/p\u003e\n\u003cp\u003eIdeal for detecting scratches, concavity, and convexity on surfaces\u003c\/p\u003e\n\u003cp\u003eHigh-quality Plan Apochromat optical design\u003c\/p\u003e\n\u003cp\u003eInfinity corrected\u003c\/p\u003e\n\u003cp\u003eLong working distance design\u003c\/p\u003e\n\u003cp\u003eOptimised for visible wavelength range (436–656 nm)\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\u003cp\u003eModel: BD Plan Apo 7.5X\u003c\/p\u003e\n\u003cp\u003eMagnification: 7.5x\u003c\/p\u003e\n\u003cp\u003eWorking distance (in air): 34 mm\u003c\/p\u003e\n\u003cp\u003eNumerical Aperture (N.A.): 0.21\u003c\/p\u003e\n\u003cp\u003eCorrected wavelength range: 436–656 nm\u003c\/p\u003e\n\u003cp\u003eResolving power: 1.3 µm\u003c\/p\u003e\n\u003cp\u003eDepth of field: 6.2 µm\u003c\/p\u003e\n\u003cp\u003eField of view (ø24 mm eyepiece): ø3.6 mm\u003c\/p\u003e\n\u003cp\u003eField of view (1\/2” camera chip): 0.64 × 0.85 mm\u003c\/p\u003e\n\u003cp\u003eSpectral range: VIS\u003c\/p\u003e\n\u003cp\u003eObservation mode: Brightfield \/ Darkfield\u003c\/p\u003e\n\u003cp\u003eGlass compensation: No\u003c\/p\u003e\n\u003cp\u003eLaser applications: No\u003c\/p\u003e\n\u003cp\u003eMass: 350 g\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56428527223164,"sku":"378-830-7","price":1296.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo378-830-7BDPlanApo7.5XObjectiveforbright_dark-fieldobservationinvisiblerange.jpg?v=1772481221","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-378-830-7-bd-plan-apo-7-5x-objective-for-bright-dark-field-observation-in-visible-range","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
