With wavelength correction from 480–1800 nm, this objective is ideal for multi-wavelength inspection and NIR laser repair environments.\u003c\/p\u003e\n\u003cp\u003eEngineered with an infinity-corrected optical system, the M Plan Apo NIR 5X maintains image focus within the depth of field even when switching between visible and near-infrared illumination. This makes it particularly suitable for inspection processes where multiple wavelengths are used.\u003c\/p\u003e\n\u003cp\u003eIts extended 37.5 mm working distance provides excellent clearance for larger components and uneven surfaces while maintaining reliable optical performance. 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\u003eExtra-long 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 5X\u003c\/p\u003e\n\u003cp\u003eMagnification: 5x\u003c\/p\u003e\n\u003cp\u003eWorking distance (in air): 37.5 mm\u003c\/p\u003e\n\u003cp\u003eNumerical Aperture (N.A.): 0.14\u003c\/p\u003e\n\u003cp\u003eCorrected wavelength range: 480–1800 nm\u003c\/p\u003e\n\u003cp\u003eResolving power: 2 µm\u003c\/p\u003e\n\u003cp\u003eDepth of field: 14 µm\u003c\/p\u003e\n\u003cp\u003eField of view (ø24 mm eyepiece): ø4.8 mm\u003c\/p\u003e\n\u003cp\u003eField of view (1\/2” camera chip): 0.96 × 1.28 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: 220 g\u003c\/p\u003e","brand":"Mitutoyo","offers":[{"title":"Default Title","offer_id":56428530008444,"sku":"378-822-5","price":763.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0724\/9428\/5114\/files\/Mitutoyo_378-822-5_M_Plan_Apo_NIR_5X_Objective_for_bright-field_observation_in_near-infrared_range.jpg?v=1772481499","url":"https:\/\/www.hroberts-di.com\/products\/mitutoyo-378-822-5-m-plan-apo-nir-5x-objective-for-bright-field-observation-in-near-infrared-range","provider":"H Roberts \u0026 Sons","version":"1.0","type":"link"}
