This makes the M Plan Apo NIR series particularly suitable for laser repair and multi-wavelength inspection applications.\u003c\/p\u003e\n\u003cp\u003eIts infinity-corrected optical design ensures flat-field imaging and reliable chromatic correction across the extended spectral range. With a 12 mm working distance and a numerical aperture of 0.50, the objective delivers a resolving power of 0.6 µm, providing high-detail imaging at maximum magnification. A High-Resolving Power (HR) version is available within the M Plan Apo NIR range for applications requiring enhanced resolution.\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\u003eDesigned to maintain focus when switching between visible and NIR wavelengths\u003c\/p\u003e\n\u003cp\u003eHigh-quality Plan Apochromat optical design\u003c\/p\u003e\n\u003cp\u003eLong working distance design\u003c\/p\u003e\n\u003cp\u003eInfinity corrected\u003c\/p\u003e\n\u003cp\u003eHR (High-Resolving Power) type available\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003c\/p\u003e\n\u003cp\u003eModel: M Plan Apo NIR 100X\u003c\/p\u003e\n\u003cp\u003eMagnification: 100x\u003c\/p\u003e\n\u003cp\u003eWorking distance (in air): 12 mm\u003c\/p\u003e\n\u003cp\u003eNumerical Aperture (N.A.): 0.50\u003c\/p\u003e\n\u003cp\u003eCorrected wavelength range: 480–1800 nm\u003c\/p\u003e\n\u003cp\u003eResolving power: 0.6 µm\u003c\/p\u003e\n\u003cp\u003eDepth of field: 1.1 µm\u003c\/p\u003e\n\u003cp\u003eField of view (ø24 mm eyepiece): ø0.24 mm\u003c\/p\u003e\n\u003cp\u003eField of view (1\/2” camera chip): 0.05 × 0.06 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: No (HR version available)\u003c\/p\u003e\n\u003cp\u003eMass: 335 g\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56428532826492,"sku":"378-826-15","price":2763.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo378-826-15MPlanApoNIR100XObjectiveforbright-fieldobservationinnear-infraredrange.jpg?v=1772482224","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-378-826-15-m-plan-apo-nir-100x-objective-for-bright-field-observation-in-near-infrared-range","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
