Designed to integrate seamlessly with the WLI Unit, this objective enables accurate surface profiling and high-resolution interferometric measurement.\u003c\/p\u003e\n\u003cp\u003eIts optical design incorporates a beam splitter and reference mirror directly within the objective, enabling compact interferometric measurements without additional external optical components. An integrated interference fringe adjustment mechanism is included as standard, allowing precise alignment and optimisation during measurement.\u003c\/p\u003e\n\u003cp\u003eThe compact and lightweight construction, combined with a 60 mm parfocal distance, ensures efficient integration into interferometry systems while maintaining a working distance of 8 mm. With a numerical aperture of 0.28, the objective delivers strong resolution while providing a larger inspection field compared with higher magnification interferometric objectives.\u003c\/p\u003e\n\u003cp\u003eOptimised for the visible spectral range, the WLI Plan Apo 5X is ideal for surface metrology, topography measurement, and precision inspection applications.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for white light interferometry (WLI)\u003c\/p\u003e\n\u003cp\u003eBeam splitter and reference mirror integrated inside the objective\u003c\/p\u003e\n\u003cp\u003eInterference fringe adjustment mechanism included as standard\u003c\/p\u003e\n\u003cp\u003eHigh numerical aperture (0.28) for improved measurement resolution\u003c\/p\u003e\n\u003cp\u003eCompact and lightweight design\u003c\/p\u003e\n\u003cp\u003eParfocal distance: 60 mm for compact optical system integration\u003c\/p\u003e\n\u003cp\u003eHigh-quality Plan Apochromat optical design\u003c\/p\u003e\n\u003cp\u003eInfinity corrected\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\u003cp\u003eModel: WLI Plan Apo 5X\u003c\/p\u003e\n\u003cp\u003eMagnification: 5x\u003c\/p\u003e\n\u003cp\u003eWorking distance: 8 mm\u003c\/p\u003e\n\u003cp\u003eNumerical Aperture (N.A.): 0.28\u003c\/p\u003e\n\u003cp\u003eResolving power: 0.98 µm\u003c\/p\u003e\n\u003cp\u003eFocal length (f): 20 mm\u003c\/p\u003e\n\u003cp\u003eParfocal distance (P.D.): 60 mm\u003c\/p\u003e\n\u003cp\u003eApplicable tube lens focal length: 100 mm\u003c\/p\u003e\n\u003cp\u003eField of view (2\/3\" camera): 1.32 × 1.76 mm\u003c\/p\u003e\n\u003cp\u003eField of view (WLI Unit): 1.46 × 1.12 mm\u003c\/p\u003e\n\u003cp\u003eObservation mode: Interferometer\u003c\/p\u003e\n\u003cp\u003eGlass compensation: No\u003c\/p\u003e\n\u003cp\u003eLaser applications: No\u003c\/p\u003e\n\u003cp\u003eSpectral range: Visible (VIS)\u003c\/p\u003e\n\u003cp\u003eMount: RMS (20.32 mm × 36 TP)\u003c\/p\u003e\n\u003cp\u003eOuter diameter: 40 mm\u003c\/p\u003e\n\u003cp\u003eMirror tube length (excluding mounting screws): 52 mm\u003c\/p\u003e\n\u003cp\u003eMass: 210 g\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56437813084540,"sku":"378-005","price":2745.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo378-005WLIPlanApo5xMirauType.jpg?v=1772650486","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-378-005-wli-plan-apo-5x-mirau-type","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
