This makes the M Plan Apo NIR series particularly suitable for laser repair and multi-wavelength inspection applications.\u003c\/p\u003e\n\u003cp\u003eAs a High-Resolving Power (HR) model, the 50X features a high numerical aperture of 0.65, delivering an impressive resolving power of 0.4 µm and a shallow depth of field for enhanced surface detail and contrast. Its infinity-corrected plan apochromat design ensures flat-field imaging and strong chromatic correction across the extended spectral range.\u003c\/p\u003e\n\u003cp\u003eDesigned for compatibility with VMU and FS-70 microscope systems, this objective provides precision imaging for advanced industrial and laboratory environments.\u003c\/p\u003e\n\u003cp\u003eNote: When operating above 1100 nm, the focusing position may deviate slightly from that in the visible range due to changes in glass dispersion and refractive index.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eSuitable for bright field inspection and laser-based applications\u003c\/p\u003e\n\u003cp\u003eWavelength correction from 480–1800 nm (Visible to Near-Infrared)\u003c\/p\u003e\n\u003cp\u003eHigh-Resolving Power (HR) design\u003c\/p\u003e\n\u003cp\u003eHigh numerical aperture (0.65) for enhanced detail\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: M Plan Apo NIR HR 50X\u003c\/p\u003e\n\u003cp\u003eMagnification: 50x\u003c\/p\u003e\n\u003cp\u003eWorking distance (in air): 10 mm\u003c\/p\u003e\n\u003cp\u003eNumerical Aperture (N.A.): 0.65\u003c\/p\u003e\n\u003cp\u003eCorrected wavelength range: 480–1800 nm\u003c\/p\u003e\n\u003cp\u003eResolving power: 0.4 µm\u003c\/p\u003e\n\u003cp\u003eDepth of field: 0.7 µm\u003c\/p\u003e\n\u003cp\u003eField of view (ø24 mm eyepiece): ø0.48 mm\u003c\/p\u003e\n\u003cp\u003eField of view (1\/2” camera chip): 0.1 × 0.13 mm\u003c\/p\u003e\n\u003cp\u003eParfocal distance (P.D.): 95 mm\u003c\/p\u003e\n\u003cp\u003eSpectral range: Near-Infrared (NIR)\u003c\/p\u003e\n\u003cp\u003eObservation mode: Brightfield\u003c\/p\u003e\n\u003cp\u003eGlass compensation: No\u003c\/p\u003e\n\u003cp\u003eHigh Resolution: Yes\u003c\/p\u003e\n\u003cp\u003eMass: 450 g\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56428532957564,"sku":"378-863-5","price":7254.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo378-863-5MPlanApoNIRHR50XHighresolutionobjectiveforbright-fieldobservationinnear-infraredrange.jpg?v=1772482868","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-378-863-5-m-plan-apo-nir-hr-50x-high-resolution-objective-for-bright-field-observation-in-near-infrared-range","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
