It enables precise 3D shape and 3D surface roughness measurement, making it ideal for advanced surface metrology and micro-topography inspection.\u003c\/p\u003e\n\u003cp\u003eUsing white light interference technology, the system delivers high Z-axis resolution even when using low-magnification objectives, allowing accurate measurement across a wide range of surfaces. Its measurement method is not dependent on the numerical aperture (NA) of the objective lens, enabling reliable measurement of high aspect ratio structures.\u003c\/p\u003e\n\u003cp\u003eThe WLI-Unit-003 offers strong resistance to vibration disturbances, ensuring stable measurement performance in industrial environments. Its compact and lightweight design, combined with compatibility with the WLI Plan Apo objective series, makes it easy to integrate into precision inspection and metrology systems.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eNon-contact surface measurement using white light interferometry\u003c\/p\u003e\n\u003cp\u003eEnables 3D shape and 3D roughness measurement\u003c\/p\u003e\n\u003cp\u003eHigh Z-axis resolution even with low-magnification lenses\u003c\/p\u003e\n\u003cp\u003eSuitable for high aspect ratio shape measurement\u003c\/p\u003e\n\u003cp\u003eMeasurement method not dependent on optical NA\u003c\/p\u003e\n\u003cp\u003eHigh robustness against vibration disturbances\u003c\/p\u003e\n\u003cp\u003eCompact and lightweight design\u003c\/p\u003e\n\u003cp\u003eCompatible with WLI Plan Apo objective lenses\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\u003cp\u003eModel: WLI-Unit-003\u003c\/p\u003e\n\u003cp\u003eApplicable objective lenses: WLI Plan Apo series\u003c\/p\u003e\n\u003cp\u003eTube lens magnification: 1X\u003c\/p\u003e\n\u003cp\u003eFocal range: 100 mm\u003c\/p\u003e\n\u003cp\u003ePower consumption: Max. 20 W\u003c\/p\u003e\n\u003cp\u003eRated voltage: AC 100–240 V \/ 50–60 Hz\u003c\/p\u003e\n\u003cp\u003eCable length: 3 m\u003c\/p\u003e\n\u003cp\u003eMeasurement Performance\u003c\/p\u003e\n\u003cp\u003eZ motion range: 8000 µm\u003c\/p\u003e\n\u003cp\u003eWLI Measurement Z Range\u003c\/p\u003e\n\u003cp\u003eHigh Throughput: 2100 µm\u003c\/p\u003e\n\u003cp\u003eStandard: 1900 µm\u003c\/p\u003e\n\u003cp\u003eHigh Definition: 1700 µm\u003c\/p\u003e\n\u003cp\u003eMeasurement Speed (20 µm range)\u003c\/p\u003e\n\u003cp\u003eHigh Throughput: 3 s\u003c\/p\u003e\n\u003cp\u003eStandard: 4 s\u003c\/p\u003e\n\u003cp\u003eHigh Definition: 6 s\u003c\/p\u003e\n\u003cp\u003eZ resolution: 4 nm\u003c\/p\u003e\n\u003cp\u003eZ repeatability (σ): 40 nm\u003c\/p\u003e\n\u003cp\u003eSystem \u0026amp; Interface\u003c\/p\u003e\n\u003cp\u003eScanning mechanism: Mitutoyo Objective Lens Scanner\u003c\/p\u003e\n\u003cp\u003eInterface: WLI-Unit sensor head terminal \/ stop connector \/ Gigabit Ethernet (2 channels)\u003c\/p\u003e\n\u003cp\u003eSoftware\u003c\/p\u003e\n\u003cp\u003eWLIPAK: WLI-Unit control library (SDK), sample code and GUI\u003c\/p\u003e\n\u003cp\u003eWLI-Unit Calibration Software: Pixel calibration\u003c\/p\u003e\n\u003cp\u003eRecommended analysis software: MCubeMap\u003c\/p\u003e\n\u003cp\u003eMass\u003c\/p\u003e\n\u003cp\u003eSensor head: 1.7 kg\u003c\/p\u003e\n\u003cp\u003eController: 2.3 kg\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56437936259452,"sku":"554-001","price":26271.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo554-001WLI-Unit-003WhiteLightInterferenceOpticalUnit.jpg?v=1772650964","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-554-001-wli-unit-003-white-light-interference-optical-unit","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
